Description The remote Advanced Message Queuing Protocol (AMQP) service supports one or more authentication mechanisms that allow credentials to be sent in the clear. Solution Disable cleartext authentication mechanisms in the AMQP configuration in ubuntu or centos machines disable unencrypted access in the configuration file. >> unencrypted" here refers to client connections. https://www.rabbitmq.com/ssl.html Steps of disabling the AMQP: https://liquidwarelabs.zendesk.com/hc/en-us/articles/360019562832-Disable-cleartext-authentication-option-in-RabbitMQ The above link used for windows vulnerability.

I have started a POC for the BIG-IP Azure deployments, which deployed successfully and I have accessed and set the password. I've deployed the helm chart for CIS, but the pod fails to start. I've tested connectivity to the Azure BIG-IP deployment from a separate pod in the same namespace and it authenticates and returns correct info. I've validated the Azure BIG-IP creds are properly formatted in a secret and that secret is getting mounted in the CIS pod. Here is the pod log with logging level set to debug: 2021/10/04 21:21:39 [DEBUG] No url in credentials directory, falling back to CLI argument 2021/10/04 21:21:39 [INFO] [INIT] Starting: Container Ingress Services - Version: 2.5.0, BuildInfo: azure-465-1952a80a2165b7fc2d3561795ad09d1eb8615136 2021/10/04 21:21:39 [INFO]TeemServer:product.apis.f5.com 2021/10/04 21:21:39 teemClient:{{CIS-Ecosystem CIS/v2.5.0 df103609-7748-43e4-95a4-6631030e67d0} mmhJU2sCd63BznXAXDh4kxLIyfIMm3Ar product.apis.f5.com} 2021/10/04 21:21:39 [DEBUG] digitalAssetId:950e75d5-7fe0-88bc-eb3c-d654ebb4de47 2021/10/04 21:21:39 [DEBUG] telemetryDatalist:[{"Agent":"as3","ConfigmapsCount":0,"DateOfCISDeploy":"2021-10-04T21:21:39.452535893Z","ExternalDNSCount":0,"IPAMSvcLBCount":0,"IPAMTransportServerCount":0,"IPAMVirtualServerCount":0,"IngressCount":0,"IngressLinkCount":0,"Mode":"cluster","PlatformInfo":"CIS/v2.5.0 K8S/v1.19.11","RoutesCount":0,"RunningInDocker":false,"SDNType":"calico","TransportServerCount":0,"VirtualServerCount":0}] 2021/10/04 21:21:39 [DEBUG] ControllerAsDocker:#{docker} 2021/10/04 21:21:40 Resp Code:204 Status:204 No Content 2021/10/04 21:21:40 [INFO] ConfigWriter started: 0xc000284570 2021/10/04 21:21:40 [DEBUG] [CCCL] ConfigWriter (0xc000284570) writing section name global 2021/10/04 21:21:40 [DEBUG] [CCCL] ConfigWriter (0xc000284570) successfully wrote section (global) 2021/10/04 21:21:40 [DEBUG] [CCCL] ConfigWriter (0xc000284570) writing section name bigip 2021/10/04 21:21:40 [DEBUG] [CCCL] ConfigWriter (0xc000284570) successfully wrote section (bigip) 2021/10/04 21:21:40 [INFO] Started config driver sub-process at pid: 21 2021/10/04 21:21:40 [DEBUG] [INIT] Invalid trusted-certs-cfgmap option provided. 2021/10/04 21:21:40 [INFO] [INIT] Creating Agent for as3 2021/10/04 21:21:40 [DEBUG] [CORE] Agent Response Worker started and blocked on channel 0xc0004e04e0 2021/10/04 21:21:40 [INFO] [AS3] Initializing AS3 Agent 2021/10/04 21:21:41 [DEBUG] [AS3] No certs appended, using only system certs 2021/10/04 21:21:41 [DEBUG] [AS3] Validating AS3 schema with as3-schema-3.28.0-3-cis.json 2021/10/04 21:21:41 [DEBUG] [AS3] posting GET BIGIP AS3 Version request on https://10.2.0.7:8443/mgmt/shared/appsvcs/info 2021/10/04 21:21:43 [ERROR] [AS3] Response body unmarshal failed: invalid character '<' looking for beginning of value 2021/10/04 21:21:43 [ERROR] [AS3] Internal Error 2021/10/04 21:21:43 [CRITICAL] [INIT] Failed to initialize as3 agent, Internal ErrorSolved2.5KViews0likes3CommentsSSL Anonymous Cipher Suites Supported
The remote host supports the use of SSL/TLS ciphers that offer no authentication at all. Solution: Reconfigure the affected application, if possible to avoid the use of anonymous ciphers. openssl ciphers -v ssl-disable-anon-ciphers What is the proper solution for the affected load balancer Haproxy linux server ?2.1KViews0likes3CommentsRedis Server Unprotected by Password Authentication

Hello I'm not sure if this is a question for AWS support or F5 but I'll start with F5support. We recently enabled 2 sets of rules on a AWS WAFv2 from F5 (F5-CVE_Managed and F5-OWASP_Managed). Once we did we started seeing a false positive for an API call with the following rule... F5#OWASP_Managed#rule_div_tag__behavior__Parameter__AllQueryArguments_Body After some further investigation we discovered the rule is tripped when we make a request which contains embeded HTML in the body and this HTML contains a div tag with a base64 encoded image. Can you give us more background information on exactly what this rule is doing and how we should go about avoiding this false positive? Andy915Views1like4CommentsSetting up a tcpdump filter

Hi, I have setup an app in Essential App Protect and want to restrict my firewall to only allow traffic from the F5 Cloud Services instance. What are the IPs/Ranges that I need to use? I have tried the ones published for DNS but it looks like IP's outside of those ranges are hitting the firewall. Thanks807Views0likes3Comments
