Overview: In the ever-evolving landscape of the digital world driven by innovation, catering to the new requirements is vital for modern application scalability, adaptability, and longevity. Multi-port support refers to the capability of a system to handle and manage multiple application ports simultaneously. This flexibility is particularly important in scenarios where a single device needs to serve diverse services. Multi-port support is essential for various reasons, including some of the below: Parallel Processing: It allows the system to process multiple app streams concurrently, enhancing efficiency and reducing latency. Diverse Services: Different applications or services often require dedicated ports to function. Multi-port support enables a system to accommodate a variety of services simultaneously. Load Balancing: Distributing application traffic across multiple ports helps balance the load, preventing bottlenecks and optimizing resource utilization. Security: Sometimes SecOps want to have testing ports opened, which allow access to applications for testing, scanning, monitoring, and addressing potential security vulnerabilities. Flexibility: Systems with multi-port support are adaptable to modern micro-service-based architectures, supporting a diverse range of applications and services. IP limitations: Since IP’s are limited, customers don’t want to use a different IP for each user, so instead they want to reserve a single IP and want to distribute load on different ports. Note: For today’s demonstration, we have deployed multiple demo applications like JuiceShop, DVWA, NGINX, F5 Air asmicro-serviceson multiple systems/ports to showcase the capabilities of multi-port support and their deployment steps are out of scope in this article. Let’s unravel three below real-world use cases of multi-port support and how it can be implemented in F5 Distributed Cloud (F5 XC) in easy-to-follow steps. Use case I – Multiple Ports In this use case, let’s assume the customer already has onboarded his backend application as an origin pool in XC. Next, the customer wants to access the same application using multiple ports, either for genuine access or for testing. For achieving this use case, follow below steps: Login to F5 XC console and navigate to “Distributed Apps” --> “Manage Load balancer” section For this use case, create a HTTP load balancer with your backend application, needed ports in csv format, type as HTTP, name, domain name as shown below. NOTE: Provide only unused ports or you will run into port conflict errors. Also configure DNS records as per your setup. Once load balancer is created successfully, validate your application is accessible on the configured port and LB domain name Use case II – Port Range In this scenario, customers have the requirement to access an application in a range of ports either for parallel processing or load balancing. For configuration, follow below steps: Login to F5 XC console and navigate to “Distributed Apps” section For this use case, create a HTTPS load balancer with your backend application, needed port range and domain name as shown below. NOTE: Provide only unused port range to avoid port conflict error. Validate your application is accessible on configured ports just like below Use case III – Origin Pool Dynamic port In this requirement, the backend application port should be dynamic and is dependent on the load balancer access port number. Let’s say a customer has multiple services running on multiple ports and wants users to access these services using a single TCP load balancer. To meet this solution, follow steps below: Login to F5 XC console and navigate to “Distributed Apps” section Next, move to “Origin Pool” section and onboard your basic backend application details and select the "origin server port" option as the "loadbalancer port" (as shown below). We can also configure health checks to LB ports instead of endpoints for better visibility. We are halfway there!!. Move to “TCP Load balancer” section and create a TCP load balancer with required port ranges and your application origin pool. Your configuration will look something like below Finally for the fun part: Once load balancer comes to a READY state, open a browser and make sure different services are accessible on configured domain name and ports shown below NOTE: For above solution to work,multiple services should be running on the configured ports of backend system and this port range should be unused by other services on the XC platform We have just scratched the surface of the the wide range of use cases of multi-port and there is a lot of demand in the market for many scenarios combining different functionalities of HTTP/HTTPS/TCP, single/multi services on same system or multiple backend systems and can also be routed to appropriate backends using port range filters in routes. As percustomer requirements, appropriate configurations can be done on F5 XC for seamless integration and to leverage the pervasive WAAP security ecosystem. Conclusion: Winding up, this article pondered the market demand for the support of multi-port range in HTTP/TCP load balancers and then we took you on a roller coaster ride of different use cases. Finally, we also demonstrated how F5 XC can foster in shaping and optimizing your application versatile multi-port requirements.

Overview This article is a continuation of the series of articles on OWASP API Security vulnerabilities and demonstrates a scenario for mitigating API Security Misconfiguration using F5 Distributed Cloud Platform. See F5 Distributed Cloud API Security dynamically discover and automatically protect API endpoints. Introduction to OWASP API Security Misconfiguration APIs are the backbone of the modern application development model and because of their heavy usage they often become victim of attacks. Sometimes these vulnerabilities arise if security best practices are missed and are not followed properly in application development life cycle. Below are a few scenarios which fall under API Security Misconfiguration category: Latest security patches are not applied. Unnecessary HTTP verbs are enabled exposing APIs to get accessed by them. Improper implementation of CORS policy. Missing repeatable security hardening process. Exposing detailed stack trace error messages or sensitive information. Problem Statement There are many ways an attacker can take advantage of security misconfigurations by utilizing readily available automation tools. In the demonstration below we will cover a scenario where the application is vulnerable for exposing stack trace information and will see how F5 Distributed Cloud WAAP can help in identifying and mitigating such threats. What is Stack Trace? Stack Trace is a system defined error message which occurs when program under execution gets abnormally terminated. This information is normally used for debugging purposes. Application throwing stack trace information gives the attacker a picture of active subroutines at that point during its execution and may help him to find flaws in the system which eventually may lead to some harmful implications. For the demonstration, we have already deployed a Load Balancer (LB) in the Distributed Cloud Console and attached the origin server to the LB. For configuration steps please follow the documentation As you can see from the above screenshot, a specific API Endpoint in our application is throwing Internal server error message along with stack trace information. F5 Distributed Cloud WAF engine can help in detecting such threats. For that you need to create a WAF policy with default configuration, enable WAF and attach theWAF policy to the LB. Configuration steps are covered in the documentation In the above screenshot you can see that Distributed Cloud WAF engine has successfully identified security misconfiguration in the API Endpoint. Prevention From the suite of security solutions offered by F5 Distributed Cloud WAAP, here we have chosen to create an ‘API Protection Rule’ to restrict the access of API Endpoint throwing stack trace information. Step1: Select Load Balancer service tile from Distributed Cloud console homepage. Step2: On the right side of your LB click on three dots (ellipsis) and select ‘Manage Configuration’ as an action, click on ‘Edit Configuration’. Step3: Scroll down, in ‘API Protection’, click ‘Configure’ API Protection Rules. Step4: In ‘API Endpoints’, click ‘Add item’, Enter a name and configure a rule to deny access to the API Endpoint ‘/test’, Click ‘Apply’ then ‘Save and Exit’. Step5: Re-visit the same API Endpoint, throwing stack trace information. In the above screenshot you can see access to the vulnerable API Endpoint is restricted successfully. Conclusion As demonstrated, the F5 Distributed Cloud WAF engine can successfully detect security misconfiguration event and optionally applying API Protection Rule on top of it can add a layer of security, safeguarding application against potential threats.

Introduction: The Introductory article covered a brief overview of OWASP Top 10 API Security risk/vulnerability. This article is a continuation of the series and shows mitigating API Vulnerability Unsafe Consumption of API using F5 Distributed Cloud (F5 XC) WAAP. See F5 Distributed Cloud API Security in action. Problem Description: The Digital transformation and modernization of Apps is accelerating to meet the market demands, which results in proliferation of architecture in data center, private/public cloud and across multi cloud which results in organizations to scramble and to gain the competitive edge. As Apps modernization involves API-based systems, those endpoints are now distributed across multiple environments, including third-party services. These third-party APIs are exposing new security risks due to interaction with them. These endpoints are trusted and not verified due to. Developers tend to adopt weaker security standards for authentication/authorization, input validation and sanitization, thereby making these APIs attractive to attackers. Solution from F5 XC: F5 XC delivers a broad approach to API security with a combination of management, monitoring/visibility, and enforcement functionalities. This allows organizations to discover third-party API endpoints, their request/response schemas, sensitive data, authentication state easily and effectively. F5 XC helps in monitoring and securing these API endpoints by performing continuous learning and inspection to provide protection against malicious users. This article aims to demonstrate validation and sanitization of data received from the third-party integrated API before processing further. Preventing unsafe consumption of API vulnerabilities using F5 XC SaaS console configs: Below are the steps that are being followed to access valid API data from the third-party Integrated API, Upload the modified swagger file Configure API Protection for Endpoints Step 1: Uploading the modified swagger file We are updating the swagger file to define API groups and set rules to control access to APIs, enabling granular API access control ability. This ensurestraffic from a third-party API complies with the specified schema. If the traffic does not conform to the API schema of third-party services, you can enable action to block the traffic, ensuring the security and integrity of your API. Note: In this case, Endpoints and expected data associated to it in the Swagger file is validated properly by the developers before uploading in F5 XC console. Login to F5 XC console and click on Multi-cloud App Connect. Select the HTTP Load Balancer by selecting “…” > Manage configuration for your load balancer to which API Protection to be enabled. Select Edit Configuration on the manage configuration screen. Go to API Protection section, From the API definition menu, select Enable to use an API definition. From the API Definition menu, select the API definition. Click “Add Item” to create a new definition. Enter name in metadata section. In Swagger Specs section, click on the drop-down menu and select “Upload Swagger file”. Enter the name in Metadata section of Swagger File. Click on Upload File button in Swagger Upload section to upload the swagger file. A sample swagger file shown below validates the email address returned by the third-party server. Once the file is uploaded, click on Continue. Select the swagger file created above from the Swagger Specs drop-down and click on Continue and page will be redirected to LB configuration page. Step 2: Configuring API Protection for Endpoints From Validation drop-down, select “All Endpoints” to enable validation for all the endpoints specified in the swagger file. In the “All endpoints” validation section, From the OpenAPI Validation Response Processing Mode menu, select validate. From the Response Validation Enforcement Type menu, select the type of enforcement as Block. From the Response Validation Properties menu, select HTTP Headers, Content-type, HTTP Body, and Response Code. Enable Show Advanced Fields button on the top right corner of the section and select Property Validation Settings to Custom and select “Disallow” for Allow/Disallow additional query parameters in Request. Click on Apply. Click on Save and Exit. In this scenario, below is the data sent by the third-party API to store the details in the database server If the third-party service returns data, which includes malicious SQL injection/payload that causes harm to the database servers during the process of transport security, authentication/authorization. In this attack scenario, a third-party API returns data consisting of 'Admin' OR 1=1--' which tries to compromise the system. This is instantly identified, cautioned, and mitigated by F5 XC. Json data logs for respective security analytics. Conclusion: With F5 XC things become easier to manage, monitor andenforce security to API services. F5 XC provides the feasibility of continuous discovery of APIs and inspectingdata received from the third-party services when configured appropriately in the Load Balancer. This helps in secure and manage APIs with the modern App and API deployment with necessary management and protection against threats.

Introduction to API An Application Programming Interface (API) is a component that enables communication between two different systems by following certain rules. It also adds a layer of abstraction between the two systems where the requester does not know how the other system has derived the result and responded back. Over the past few years, developers have started relying more on APIs as it helps them to meet the needs of today’s rapid application deployment model. As the APIs started getting a wider acceptance it is highly critical to safeguard them by thoroughly testing their behavior and following best securitypractices. Learn API Security Best Practices. Overview of OWASP API Security The OWASP API Security project aims to help the organizations by providing a guide with a list of the latest top 10 most critical API vulnerabilities and steps to mitigate them. As part of updating the old OWASP API Security risk categories of 2019, recently OWASP API Security Top 10 2023 is released. What’s new in OWASP API Sec 2023? List of vulnerabilities: API1:2023 Broken Object Level Authorization Broken Object Level Authorization (BOLA) is a vulnerability that occurs when there is a failure in validation of user’s permissions to perform a specific task over an object which may eventually lead to leakage, updation or destruction of data. To prevent this vulnerability,proper authorization mechanism should be followed, proper checks should be made to validate user’s action on a certain record and security tests should be performedbefore deploying any production grade changes. API2:2023 Broken Authentication Broken Authentication is a critical vulnerability that occurs when application’s authentication endpoints fail to detect attackers impersonating someone else’s identity and allow partial or full control over the account. To prevent this vulnerability,observability and understanding of all possible authentication API endpoints is needed, re-authentication should be performed for any confidential changes, multi-factor authentication, captcha-challenge and effective security solutions should be appliedto detect &mitigate credential stuffing, dictionary and brute force type of attacks. API3:2023 Broken Object Property Level Authorization Broken Object Property Level Authorization is one of the new risk categories of OWASP API Security Top 10 2023 RC. This vulnerability occurs when a user is allowed to access an object’s property without validating his access permissions. Excessive Data Exposure and Mass Assignment which were a part of OWASP APISec 2019 are now part of this new vulnerability. To prevent this vulnerability, access privileges of users requesting for a specific object's propertyshould be scrutinized before exposureby the API endpoints. Use of generic methods &automatically binding client inputs to internal objects or code variables should be avoided and schema-based validation should be enforced. API4:2023 Unrestricted Resource Consumption Unrestricted Resource Consumption vulnerability occurs when the system’s resources are being unnecessarily consumed which could eventually lead to degradation of services and performance latency issues.Although the name has changed,the vulnerability is still the same asthat of Lack of Resources & Rate Limiting. To prevent this vulnerability, rate-limiting, maximum size forinput payload/parameters and server-side validations of requests should be enforced. API5:2023 Broken Function Level Authorization Broken Function Level Authorization occurs when vulnerable API endpoints allow normal users to perform administrative actions or user from one group is allowed to access a function specific to users of another group. To prevent this vulnerability, access control policies and administrative authorization checks based on user’s group/roles should be implemented. API6:2023Unrestricted Access to Sensitive Business Flows Unrestricted Access to Sensitive Business Flows is also a new addition to the list of API vulnerabilities. While writing API endpoints it is extremely critical for the developers to have a clear understanding of the business flows getting exposed by it. To avoid exposing any sensitive business flow and limit its excessive usage which if not considered, might eventually lead to exploitation by the attackers and cause some serious harm to the business. This also includes securing and limiting access to B2B APIs that are consumed directly and often integrated with minimal protection mechanism. By keeping automation to work, now-a-days attackers can bypass traditional protection mechanisms. APIs inefficiency in detecting automated bot attacks not only causes business loss but also it can adversely impact the services for real users as well. To overcome this vulnerability, enterprises need to have a platform to identify whether the request is from a real user or an automated tool by analyzing and tracking patterns of usage. Device fingerprinting, Integrating Captcha solution, blocking Tor requests, are a few methods which can help to minimize the impact of such automated attacks. For more details on automated threats, you can visit OWASP Automated Threats to Web Applications Note: Although the vulnerability is new but it contains some references ofAPI10:2019 Insufficient Logging & Monitoring API7:2023 Server-Side Request Forgery After finding a place in OWASP Top 10 web application vulnerabilities of 2021, SSRF has now been included in OWASP API Security Top 10 2023 RC list as well, showing the severity of this vulnerability. Server-Side Request Forgery (SSRF) vulnerability occurs when an API fetches an internal server resource without validating the URL from the user. Attackers exploit this vulnerability by manipulating the URL, which in turn helps them to retrieve sensitive data from the internal servers. To overcome this vulnerability, Input data validations should be implemented to ensure that the client supplied input dataobeys the expected format. Allow lists should be maintained so thatonly trusted requests/calls will be processed, andHTTP redirections should be disabled. API8:2023 Security Misconfiguration Security Misconfiguration is a vulnerability that may arise when security best practices are overlooked. Unwanted exposure of debug logs, unnecessary enabled HTTP Verbs, unapplied latest security patches, missing repeatable security hardening process, improper implementation of CORS policy etc. are a few examples of security misconfiguration. To prevent this vulnerability, systems and entire API stack should be maintained up to date without missing any security patches. Continuous security hardening and configurations tracking process should be carried out. Make sure all API communications take place over a secure channel (TLS) and all servers in HTTP server chain process incoming requests. Cross-Origin Resource Sharing (CORS) policy should be set up properly. Unnecessary HTTP verbs should be disabled. API9:2023 Improper Inventory Management Improper Inventory Management vulnerability occurs when organizations don’t have much clarity on their own APIs as well as third-party APIs that they use and lack proper documentation. Unawareness with regards to current API version, environment, access control policies, data shared with the third-party etc. can lead to serious business repercussions. Clear understanding and proper documentation arethe keyto overcome this vulnerability.All the details related to API hosts, API environment, Network access, API version, Integrated services, redirections, rate limiting, CORS policy should be documented correctly and maintained up to date.Documenting every minor detail is advisable and authorized access should be given to these documents. Exposed API versions should be secured along with the production version. A risk analysis is recommended whenever newer versions of APIs are available. API10:2023 Unsafe Consumption of APIs Unsafe Consumption of APIs is again a newly added vulnerability covering a portion of API8:2019 Injectionvulnerability. This occurs when developers tend to apply very little or no sanitization on the data received from third-party APIs. To overcome this, we should make sure that API interactions take place over an encrypted channel. API data evaluation and sanitization should be carried out before using the data further. Precautionary actions should be taken to avoid unnecessary redirections by using Allow lists. How F5 XC can help?

Introduction: In this OWASP Automated Threat Article we'll be highlighting OAT-008 Credentials Stuffing with some basic threat information as well as a recorded demo to dive into the concepts deeper. In our demo we'll show how Credential Stuffing works with Automation Tools to validate lists of stolen credentials leading to manual Account Takeover and Fraud. We'll wrap it up by highlightingF5 Bot Defenseto show how we solve this problem for our customers. Credential Stuffing Description: Lists of authentication credentials stolen from elsewhere are tested against the application’s authentication mechanisms to identify whether users have re-used the same login credentials. The stolen usernames (often email addresses) and password pairs could have been sourced directly from another application by the attacker, purchased in a criminal marketplace, or obtained from publicly available breach data dumps. Unlike OAT-007 Credential Cracking, Credential Stuffing does not involve any bruteforcing or guessing of values; instead credentials used in other applications are being tested for validity Likelihood & Severity Credential stuffing is one of the most common techniques used to take-over user accounts. Credential stuffing is dangerous to both consumers and enterprises because of the ripple effects of these breaches. Anatomy of Attack The attacker acquires usernames and passwords from a website breach, phishing attack, password dump site. The attacker uses automated tools to test the stolen credentials against many websites (for instance, social media sites, online marketplaces, or web apps). If the login is successful, the attacker knows they have a set of valid credentials. Now the attacker knows they have access to an account. Potential next steps include: Draining stolen accounts of stored value or making purchases. Accessing sensitive information such as credit card numbers, private messages, pictures, or documents. Using the account to send phishing messages or spam. Selling known-valid credentials to one or more of the compromised sites for other attackers to use. OWASP Automated Threat (OAT) Identity Number OAT-008 Threat Event Name Credential Stuffing Summary Defining Characteristics Mass log in attempts used to verify the validity of stolen username/password pairs. OAT-008 Attack Demographics: Sectors Targeted Parties Affected Data Commonly Misused Other Names and Examples Possible Symptoms Entertainment Many Users Authentication Credentials Account Checker Attack Sequential login attempts with different credentials from the same HTTP client (based on IP, User Agent, device, fingerprint, patterns in HTTP headers, etc.) Financial Application Owner Account Checking High number of failed login attempts Government Account Takeover Increased customer complaints of account hijacking through help center or social media outlets Retail Login Stuffing Social Networking Password List Attack Password re-use Use of Stolen Credentials Credential Stuffing Demo: In this demo we will be showing how attackers leverage automation tools with increasing sophistication to execute credential stuffing against the sign in page of a web application. We'll then have a look at the same attack with F5 Distributed Cloud Bot Defense protecting the application. In Conclusion: A common truism in the security industry says that there are two types of companies—those that have been breached, and those that just don’t know it yet. As of 2022, we should be updating that to something like “There are two types of companies—those that acknowledge the threat of credential stuffing and those that will be its victims.” Credential stuffing will be a threat so long as we require users to log in to accounts online. The most comprehensive way to prevent credential stuffing is to use an anti-automation platform.

Introduction Many of us have heard of OWASP in the context of the OWASP Top 10. In this article series we will take a look at another very important threat classification list called the OWASP Automated Threats (OAT) Project and provide a foundational overview. The terms Malicious Bot and Automated Threat can be used interchangeably throughout. In future articles we'll dive deeper into individual key threats called OATs and demonstrate how these attacks work and how to defend against them. Why should we care about the OWASP Automated Threats Project? Web security is no longer constrained to inadvertent vulnerabilities and attackers are abusing inherent functionality to conduct Automated and Manual Fraud. Existing technologies are not capable of detecting advancedautomated abuse, fraud teams can’t keep up with new fraud mechanisms,while web users are increasingly adverse to encountering Authentication Friction created by legacy or traditional bot defenses like CAPTCHAs. From its original release in 2015, the OWASP Automated Threat Handbook has now become a de facto industry standard in classifying Bots and better understanding all aspects of Malicious Web Automation. What OATs Are Not - Not another vulnerability list - Not an OWASP Top N List - Not threat modelling - Not attack trees - Not non web - Not non application What Are OATs (aka Malicous Bots)? In order to quantify these threats, it is necessary to be able to name them. OAT stands for OWASP Automated Threat and there are currently 21 attack vectors defined. Currently OAT codes 001 to 021 are used. Within each OAT the Threat definition contains a description, the sectors targeted, parties affected, the data commonly misused, and external cross mappings to other lists like CAPEC Category, possible symptoms, suggested countermeasures, etc... Here is the Full List of OATs ordered by ascending name: Identifier OAT Name Summary Defining Characteristics OAT-020 Account Aggregation Use by an intermediary application that collects together multiple accounts and interacts on their behalf OAT-019 Account Creation Create multiple accounts for subsequent misuse OAT-003 Ad Fraud False clicks and fraudulent display of web-placed advertisements OAT-009 CAPTCHA Defeat Solve anti-automation tests OAT-010 Card Cracking Identify missing start/expiry dates and security codes for stolen payment card data by trying different values OAT-001 Carding Multiple payment authorisation attempts used to verify the validity of bulk stolen payment card data OAT-012 Cashing Out Buy goods or obtain cash utilising validated stolen payment card or other user account data OAT-007 Credential Cracking Identify valid login credentials by trying different values for usernames and/or passwords OAT-008 Credential Stuffing Mass log in attempts used to verify the validity of stolen username/password pairs OAT-021 Denial of Inventory Deplete goods or services stock without ever completing the purchase or committing to the transaction OAT-015 Denial of Service Target resources of the application and database servers, or individual user accounts, to achieve denial of service (DoS) OAT-006 Expediting Perform actions to hasten progress of usually slow, tedious or time-consuming actions OAT-004 Fingerprinting Elicit information about the supporting software and framework types and versions OAT-018 Footprinting Probe and explore application to identify its constituents and properties OAT-005 Scalping Obtain limited-availability and/or preferred goods/services by unfair methods OAT-011 Scraping Collect application content and/or other data for use elsewhere OAT-016 Skewing Repeated link clicks, page requests or form submissions intended to alter some metric OAT-013 Sniping Last minute bid or offer for goods or services OAT-017 Spamming Malicious or questionable information addition that appears in public or private content, databases or user messages OAT-002 Token Cracking Mass enumeration of coupon numbers, voucher codes, discount tokens, etc OAT-014 Vulnerability Scanning Crawl and fuzz application to identify weaknesses and possible vulnerabilities Automated Threats Breakdown By Industry Within each OAT definition there is a section for the Sectors Targeted for that particular attack vector. For example, a Carding Attack would be seen on ecommerce and retail type of sites with payment card processing. Here they would be able to validate a list of stolen credit card numbers to identify the working ones from non working. Example: OAT-001 Carding Attack example highlighting "Sectors Targeted" for this type of attack. This exists for each attack definition. OWASP Defined Countermeasures Countermeasure Classes: The technology and vendor agnostic countermeasure classes attempt to group together the types of design, development and operational controls identified from research that are being used to partially or fully mitigate the likelihood and/or impact of automated threats to web applications. In all applications, builder-defender collaboration is key in controlling and mitigating automated threats – the best protected applications do not rely solely upon standalone external operational protections, but also have integrated protection built into the design. Similarly to other types of application security threat, it is important to build consideration of automated threats into multiple phases of a secure software development lifecycle (S-SDLC). 14 Countermeasure Classes: Value Authentication Requirements Rate Testing Monitoring Capacity Instrumentation Obfuscation Contract Fingerprinting Response Reputation Sharing Countermeasure Controls Countermeasures are controls that attempt to mitigate the identified automated threats in three ways: Prevent - Controls to reduce the susceptibility to automated threats Detect - Controls to identify whether a user is an automated process rather than a human, and/or to identify if an automated attack is occurring, or occurred in the past Recover - Controls to assist response to incidents caused by automated threats, including to mitigate the impact of the attack, and to to assist return of the application to its normal state. Cross References Other Threat Mappings Each OAT Threat is cross referenced with other external threat lists to provide and understanding of how this OAT Handbook can be integrated with other works.
