Bypass "Bad unescape" in Body POST (ASM, POST, JSON)
Here the Block. As you can see is "%" is detected without encoding meaning. This is normal since the "%" is in the Body of the post as JSON data (see below) Of course if I disable the "Bad unescape" in " Learning and Blocking Settings" it works, but my Goal is to bypass using rule on parameter or similar, till now without success. Does anyone have a solution ? ======= JSON on POST Dody Request =======================
5 Years Later: OpenAJAX Who?
Five years ago the OpenAjax Alliance was founded with the intention of providing interoperability between what was quickly becoming a morass of AJAX-based libraries and APIs. Where is it today, and why has it failed to achieve more prominence? I stumbled recently over a nearly five year old article I wrote in 2006 for Network Computing on the OpenAjax initiative. Remember, AJAX and Web 2.0 were just coming of age then, and mentions of Web 2.0 or AJAX were much like that of “cloud” today. You couldn’t turn around without hearing someone promoting their solution by associating with Web 2.0 or AJAX. After reading the opening paragraph I remembered clearly writing the article and being skeptical, even then, of what impact such an alliance would have on the industry. Being a developer by trade I’m well aware of how impactful “standards” and “specifications” really are in the real world, but the problem – interoperability across a growing field of JavaScript libraries – seemed at the time real and imminent, so there was a need for someone to address it before it completely got out of hand. With the OpenAjax Alliance comes the possibility for a unified language, as well as a set of APIs, on which developers could easily implement dynamic Web applications. A unifiedtoolkit would offer consistency in a market that has myriad Ajax-based technologies in play, providing the enterprise with a broader pool of developers able to offer long term support for applications and a stable base on which to build applications. As is the case with many fledgling technologies, one toolkit will become the standard—whether through a standards body or by de facto adoption—and Dojo is one of the favored entrants in the race to become that standard. -- AJAX-based Dojo Toolkit , Network Computing, Oct 2006 The goal was simple: interoperability. The way in which the alliance went about achieving that goal, however, may have something to do with its lackluster performance lo these past five years and its descent into obscurity. 5 YEAR ACCOMPLISHMENTS of the OPENAJAX ALLIANCE The OpenAjax Alliance members have not been idle. They have published several very complete and well-defined specifications including one “industry standard”: OpenAjax Metadata. OpenAjax Hub The OpenAjax Hub is a set of standard JavaScript functionality defined by the OpenAjax Alliance that addresses key interoperability and security issues that arise when multiple Ajax libraries and/or components are used within the same web page. (OpenAjax Hub 2.0 Specification) OpenAjax Metadata OpenAjax Metadata represents a set of industry-standard metadata defined by the OpenAjax Alliance that enhances interoperability across Ajax toolkits and Ajax products (OpenAjax Metadata 1.0 Specification) OpenAjax Metadata defines Ajax industry standards for an XML format that describes the JavaScript APIs and widgets found within Ajax toolkits. (OpenAjax Alliance Recent News) It is interesting to see the calling out of XML as the format of choice on the OpenAjax Metadata (OAM) specification given the recent rise to ascendancy of JSON as the preferred format for developers for APIs. Granted, when the alliance was formed XML was all the rage and it was believed it would be the dominant format for quite some time given the popularity of similar technological models such as SOA, but still – the reliance on XML while the plurality of developers race to JSON may provide some insight on why OpenAjax has received very little notice since its inception. Ignoring the XML factor (which undoubtedly is a fairly impactful one) there is still the matter of how the alliance chose to address run-time interoperability with OpenAjax Hub (OAH) – a hub. A publish-subscribe hub, to be more precise, in which OAH mediates for various toolkits on the same page. Don summed it up nicely during a discussion on the topic: it’s page-level integration. This is a very different approach to the problem than it first appeared the alliance would take. The article on the alliance and its intended purpose five years ago clearly indicate where I thought this was going – and where it should go: an industry standard model and/or set of APIs to which other toolkit developers would design and write such that the interface (the method calls) would be unified across all toolkits while the implementation would remain whatever the toolkit designers desired. I was clearly under the influence of SOA and its decouple everything premise. Come to think of it, I still am, because interoperability assumes such a model – always has, likely always will. Even in the network, at the IP layer, we have standardized interfaces with vendor implementation being decoupled and completely different at the code base. An Ethernet header is always in a specified format, and it is that standardized interface that makes the Net go over, under, around and through the various routers and switches and components that make up the Internets with alacrity. Routing problems today are caused by human error in configuration or failure – never incompatibility in form or function. Neither specification has really taken that direction. OAM – as previously noted – standardizes on XML and is primarily used to describe APIs and components - it isn’t an API or model itself. The Alliance wiki describes the specification: “The primary target consumers of OpenAjax Metadata 1.0 are software products, particularly Web page developer tools targeting Ajax developers.” Very few software products have implemented support for OAM. IBM, a key player in the Alliance, leverages the OpenAjax Hub for secure mashup development and also implements OAM in several of its products, including Rational Application Developer (RAD) and IBM Mashup Center. Eclipse also includes support for OAM, as does Adobe Dreamweaver CS4. The IDE working group has developed an open source set of tools based on OAM, but what appears to be missing is adoption of OAM by producers of favored toolkits such as jQuery, Prototype and MooTools. Doing so would certainly make development of AJAX-based applications within development environments much simpler and more consistent, but it does not appear to gaining widespread support or mindshare despite IBM’s efforts. The focus of the OpenAjax interoperability efforts appears to be on a hub / integration method of interoperability, one that is certainly not in line with reality. While certainly developers may at times combine JavaScript libraries to build the rich, interactive interfaces demanded by consumers of a Web 2.0 application, this is the exception and not the rule and the pub/sub basis of OpenAjax which implements a secondary event-driven framework seems overkill. Conflicts between libraries, performance issues with load-times dragged down by the inclusion of multiple files and simplicity tend to drive developers to a single library when possible (which is most of the time). It appears, simply, that the OpenAJAX Alliance – driven perhaps by active members for whom solutions providing integration and hub-based interoperability is typical (IBM, BEA (now Oracle), Microsoft and other enterprise heavyweights – has chosen a target in another field; one on which developers today are just not playing. It appears OpenAjax tried to bring an enterprise application integration (EAI) solution to a problem that didn’t – and likely won’t ever – exist. So it’s no surprise to discover that references to and activity from OpenAjax are nearly zero since 2009. Given the statistics showing the rise of JQuery – both as a percentage of site usage and developer usage – to the top of the JavaScript library heap, it appears that at least the prediction that “one toolkit will become the standard—whether through a standards body or by de facto adoption” was accurate. Of course, since that’s always the way it works in technology, it was kind of a sure bet, wasn’t it? WHY INFRASTRUCTURE SERVICE PROVIDERS and VENDORS CARE ABOUT DEVELOPER STANDARDS You might notice in the list of members of the OpenAJAX alliance several infrastructure vendors. Folks who produce application delivery controllers, switches and routers and security-focused solutions. This is not uncommon nor should it seem odd to the casual observer. All data flows, ultimately, through the network and thus, every component that might need to act in some way upon that data needs to be aware of and knowledgeable regarding the methods used by developers to perform such data exchanges. In the age of hyper-scalability and über security, it behooves infrastructure vendors – and increasingly cloud computing providers that offer infrastructure services – to be very aware of the methods and toolkits being used by developers to build applications. Applying security policies to JSON-encoded data, for example, requires very different techniques and skills than would be the case for XML-formatted data. AJAX-based applications, a.k.a. Web 2.0, requires different scalability patterns to achieve maximum performance and utilization of resources than is the case for traditional form-based, HTML applications. The type of content as well as the usage patterns for applications can dramatically impact the application delivery policies necessary to achieve operational and business objectives for that application. As developers standardize through selection and implementation of toolkits, vendors and providers can then begin to focus solutions specifically for those choices. Templates and policies geared toward optimizing and accelerating JQuery, for example, is possible and probable. Being able to provide pre-developed and tested security profiles specifically for JQuery, for example, reduces the time to deploy such applications in a production environment by eliminating the test and tweak cycle that occurs when applications are tossed over the wall to operations by developers. For example, the jQuery.ajax() documentation states: By default, Ajax requests are sent using the GET HTTP method. If the POST method is required, the method can be specified by setting a value for the type option. This option affects how the contents of the data option are sent to the server. POST data will always be transmitted to the server using UTF-8 charset, per the W3C XMLHTTPRequest standard. The data option can contain either a query string of the form key1=value1&key2=value2 , or a map of the form {key1: 'value1', key2: 'value2'} . If the latter form is used, the data is converted into a query string using jQuery.param() before it is sent. This processing can be circumvented by setting processData to false . The processing might be undesirable if you wish to send an XML object to the server; in this case, change the contentType option from application/x-www-form-urlencoded to a more appropriate MIME type. Web application firewalls that may be configured to detect exploitation of such data – attempts at SQL injection, for example – must be able to parse this data in order to make a determination regarding the legitimacy of the input. Similarly, application delivery controllers and load balancing services configured to perform application layer switching based on data values or submission URI will also need to be able to parse and act upon that data. That requires an understanding of how jQuery formats its data and what to expect, such that it can be parsed, interpreted and processed. By understanding jQuery – and other developer toolkits and standards used to exchange data – infrastructure service providers and vendors can more readily provide security and delivery policies tailored to those formats natively, which greatly reduces the impact of intermediate processing on performance while ensuring the secure, healthy delivery of applications.Disable buffer overflow in json parameters
Hi In a file upload using api we allow the file name in base64 encoding. However this triggers the Generic buffer overflow attempt 1 . As of this post it seems signature at json parameter level cannot be disabled. https://devcentral.f5.com/questions/disable-attack-signature-on-particular-json-parametercomment77010 Has there been any change in this? I am using v12? In my json content profile I do not see the buffer overflow sig at all on filtering with the name.
HTTPS Monitor: JSON File behind login page
Hello, we've already a https monitor that reads the contents of a json file, it looks like this: send string: GET /intern/api/v1/health/portal-status HTTP/1.1\r\nHost: host.company.com\r\n\r\n receive strimg: \"portalStatus\":\"AVAILABLE\" this works fine. but now I need a similar monitor, but the json file is passwort protectet, when I add username/password to the monitor, it doesn't work. when I do a curl: curl -sku monitor:<pw> -H "Content-Type: application/json" -X GET https://host.company.int/monitor/wga/widgets/health.json I get the logon-page for the username/pw I tried some other parameter for curl, but I don't get the content of the json-file. Any ideas? thanks in advance
ASM JSON/XML payload detection & Automatically detect advanced protocols
Hello team, I have a question regarding the learning suggestions, I want to know if it is possible for the ASM to suggest the association of an XML profile to a specific URL. In other words, is there a way to configure the ASM so that when XML traffic passes through it then a learning suggestion rises saying "you have to associate an XML for this URL" In this article : https://support.f5.com/kb/en-us/products/big-ip_asm/manuals/product/asm-getting-started-12-1-0/3.html The Policy Builder builds the security policy as follows: Examines application content and creates XML or JSON profiles as needed (if the policy includes JSON/XML payload detection) ...etc we can read explicitly that it is possible IF we enable the "JSON/XML payload detection" then the answer to my question is "Yes" . The problem is that I can't find this "JSON/XML payload detection" option in the GUI. Could you please help on this ? Many thanks, KarimIs there ressources to mock iControlREST?
Hello all, Is there a huge zip file somewhere with a complete dump of a "classic" F5 installation with virtual servers, policies, etc. I want to mock a iControlREST for unit testing and integration testing of one of our service that use iControl REST but not with production data that can be sensitive and doesn’t belong in a CI/CD chain. Thank you!
Authorization Header Defined as Unparsable by F5_ASM
One of our development teams is adding a new OAUTH token feature to an application. Sending the JSON call with the Authorization header creates an error within F5_ASM (ver 15.13): HTTP ValidationUnparsable request content Details Unparsable authorization header value I also see that the Authorization header's data is masked, though there's no settings for the Authorization header in the policy. What are my best options for troubleshooting this issue?F5 SSLO Unified Configuration API Quick Introduction
Introduction Prior to the introduction of BIG-IQ 8.0, you had to use the BIG-IQ graphical user interface (GUI) to configure F5 SSL Orchestrator (SSLO) Topologies and their dependencies. Starting with BIG-IQ 8.0, a new REST unified, supported and documented REST API endpoint was created to simplify SSLO configuration workflows. The aim is to simplify the configuration of F5 SSLO using standardized API calls.You are now able to store the configuration in your versioning tool (Git, SVN, etc.), and easily integrate the configuration of F5 SSLO in your automation and pipeline tools. For more information about F5 SSLO, please refer to this introductory video.An overview of F5 SSL Orchestrator is provided in K1174564. As a reminder the BIG-IQ API reference documentation can be found here.Documentation for the Access Simplified Workflow can be found here. The figure below shows a possible use for the SSLO Unified API. A few shortcuts are taken in the figure above as it is meant to illustrate the advantage of the simplified workflow. Example Configuration For the configuration the administrator needs to: -Create a JSON blurb or payload that will be sent to the BIG-IQ API -Authenticate to the BIG-IQ API -Send the payload to the BIG-IQ -Ensure that the workflow completes successfully The following aims to provide a step-by-step configuration of SSLO leveraging the API.In practice, the steps may be automated and may be included in the pipeline used to deploy the application leveraging the enterprise tooling and processes in place. 1.- Authenticate to the API API interactions with the BIG-IQ API requires the use of a token.The initial REST call should look like the following: REST Endpoint : /mgmt/shared/authn/login HTTP Method: POST Headers: -content-type: application/json Content: { "username": "", "password": "", "loginProviderName": "" } Example: POST https://10.0.0.1/mgmt/shared/authn/login HTTP/1.1 Headers: content-type: application/json Content: { "username": "username", "password": "complicatedPassword!", "loginProviderName": "RadiusServer" } The call above will authenticate the user “bob” to the API.The result of a successful authentication is the response from the BIG-IQ API with a token. 2.- Push the configuration to BIG-IQ The headers and HTTP request should look like the following: URI: mgmt/cm/sslo/api/topology HTTP Method: POST Headers: -content-type: application/json -X-F5-Auth-Token: [token obtained from the authentication process above] To send the configuration to the BIG-IQ you will need to send the following payload - the blurb is cut up in smaller pieces for readability. The JSON blurb is divided in multiple parts - the full concatenated text is available in the file in attachment. Start by defining an new topology with the following characteristics: Name: "sslo_NewTopology" Listening on the "/Common/VLAN_TRAP" VLAN The topology is of type "topology_l3_outbound" The SSL settings defined below named: "ssloT_NewSsl_Dec" The policy is called: "ssloP_NewPolicy_Dec" The JSON payload starts with the following: { "template": { "TOPOLOGY": { "name": "sslo_NewTopology ", "ingressNetwork": { "vlans": [ { "name": "/Common/VLAN_TAP" } ] }, "type": "topology_l3_outbound", "sslSetting": "ssloT_NewSsl_Dec", "securityPolicy": "ssloP_NewPolicy_Dec" }, The SSL settings used above are defined in the following JSON that creates a new profile with default values: "SSL_SETTINGS": { "name": "ssloT_NewSsl_Dec" }, The security policy is configured as follows: name: ssloP_NewPolicy_Dec function: introduces a pinning policy doing a policy lookup - matching requests are bypassed (no ssl decryp) with the associated service chain "ssloSC_NewServiceChain_Dec" that is defined further down below. "SECURITY_POLICY": { "name": "ssloP_NewPolicy_Dec", "rules": [ { "mode": "edit", "name": "Pinners_Rule", "action": "allow", "operation": "AND", "conditions": [ { "type": "SNI Category Lookup", "options": { "category": [ "Pinners" ] } }, { "type": "SSL Check", "options": { "ssl": true } } ], "actionOptions": { "ssl": "bypass", "serviceChain": "ssloSC_NewServiceChain_Dec" } }, { "mode": "edit", "name": "All Traffic", "action": "allow", "isDefault": true, "operation": "AND", "actionOptions": { "ssl": "intercept" } } ] }, The service chain configuration is defined below to forward the traffic to the "ssloS_ICAP_Dec" service. this is done with the following JSON: "SERVICE_CHAIN": { "ssloSC_NewServiceChain_Declarative": { "name": "ssloSC_NewServiceChain_Dec", "orderedServiceList": [ { "name":"ssloS_ICAP_Dec" } ] } }, The "ssloS_ICAP_Dec" service is defined with the JSON below with IP 3.3.3.3 on port 1344 "SERVICE": { "ssloS_ICAP_Declarative": { "name": "ssloS_ICAP_Dec", "customService": { "name": "ssloS_ICAP_Dec", "serviceType": "icap", "loadBalancing": { "devices": [ { "ip": "3.3.3.3", "port": "1344" } ] } } } } }, The configuration will be deployed to the target defined below: "targetList": [ { "type": "DEVICE", "name": "my.bigip.internal" } ] } After the HTTP POST, the BIG-IQ will respond with a transaction id.A sample of what looks like is given below: { […] "id":"edc17b06-8d97-47e1-9a78-3d47d2db70a6", "status":"STARTED", […] } You can check on the status of the deployment task by submitting a request as follows: -HTTP GET Method -Authenticated with the use of the custom authentication header X-F5-Auth-Token -Sent to the BIG-IQ to URI GET mgmt/cm/sslo/tasks/api/{{status_id}} HTTP/1.1 -With Content-Type header set to: Application/JSON Once the status of the task changes to FINISHED.The configuration is successfully completed.You can now check the F5 SSLO interface to make sure the new topology has been created.The BIG-IQ interface will show the new topology as depicted in the example below: The new topology has been deployed to the BIG-IP automatically.You can connect to the BIG-IP to verify, the interface should like the one depicted below: Congratulations, you now have successfully deployed a fully functional topology that your users can start using. Note that, you can also use the BIG-IQ REST API to delete the items that were just created.This is done by sending HTTP DELETE to the different API endpoints for the topology, service, security profile etc. For example, for the example above, you would be sending HTTP DELETE requests to the following URI’s: -For the topology: /mgmt/cm/sslo/api/topology/sslo_NewTopology_Dec -For the service chain: /mgmt/cm/sslo/api/service-chain/ssloSC_NewServiceChain_Dec -For the ICAP service: /mgmt/cm/sslo/api/ssl/ssloT_NewSsl_Dec All the requests listed above need to be sent to the BIG-IQ system to its management IP address with the following 2 headers: -content-type: application/json -X-F5-Auth-Token: [value of the authentication token obtained during authentication] Conclusion BIG-IQ makes it easier to manage SSLO Topologies thanks to its REST API.You can now make supported, standardized API calls to the BIG-IQ to create and modify topologies and deploy the changes directly to BIG-IP.

JMESPath and json_query JMESPath (JSON Matching Expression paths) is a query language for searching JSON documents. It allows you to declaratively extract elements from a JSON document. Have a look at this tutorial to learn more. The json_query filter lets you query a complex JSON structure and iterate over it using a loop structure.This filter is built upon jmespath, and you can use the same syntax as jmespath. Click here to learn more about the json_query filter and how it is used in Ansible. In this article we are going to use the bigip_device_info module to get various facts from the BIG-IP and then use the json_query filter to parse the output to extract relevant information. Ansible bigip_device_info module Playbook to query the BIG-IP and gather system based information. - name: "Get BIG-IP Facts" hosts: bigip gather_facts: false connection: local tasks: - name: Query BIG-IP facts bigip_device_info: provider: validate_certs: False server: "xxx.xxx.xxx.xxx" user: "*****" password: "*****" gather_subset: - system-info register: bigip_facts - set_fact: facts: '{{bigip_facts.system_info}}' - name: debug debug: msg="{{facts}}" To view the output on a different subset, below are a few examples to change the gather_subset and set_fact values in the above playbook from gather_subset: system-info, facts: bigip_facts.system_info to any of the below: gather_subset: vlans , facts: bigip_facts.vlans gather_subset: self-ips, facts: bigip_facts.self_ips gather_subset: nodes. facts: bigip_facts.nodes gather_subset: software-volumes, facts: bigip_facts.software_volumes gather_subset: virtual-servers, facts: bigip_facts.virtual_servers gather_subset: system-info, facts: bigip_facts.system_info gather_subset: ltm-pools, facts: bigip_facts.ltm_pools Click here to view all the information that can be obtained from the BIG-IP using this module. Parse the JSON output Once we have the output lets take a look at how to parse the output. As mentioned above the jmespath syntax can be used by the json_query filter. Step 1: We will get the jmespath syntax for the information we want to extract Step 2: We will see how the jmespath syntax and then be used with json_query in an Ansible playbook The website used in this article to try out the below syntax: https://jmespath.org/ Some BIG-IP sample outputs are attached to this article as well (Check the attachments section after the References). The attachment file is a combined output of a few configuration subsets.Copy paste the relevant information from the attachment to test the below examples if you do not have a BIG-IP. System information The output for this section is obtained with above playbook using parameters: gather_subset: system-info, facts: bigip_facts.system_info Once the above playbook is run against your BIG-IP or if you are using the sample configuration attached, copy the output and paste it in the relevant text box.
