In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and WebSafe software version 13.0.0 and 12.1.0 - 12.1.2, malicious requests made to virtual servers with an HTTP profile can cause the TMM to restart. The issue is exposed with BIG-IP APM profiles, regardless of settings. The issue is also exposed with the non-default "normalize URI" configuration options used in iRules and/or BIG-IP LTM policies.

Security readout for executives and security teams

CVE-2017-6138 is a denial-of-service issue in specific F5 BIG-IP versions. Malicious HTTP requests to affected virtual servers can restart the Traffic Management Microkernel, potentially interrupting application delivery through the device. Organizations running the listed BIG-IP versions with HTTP-profile virtual servers are the main exposure group. APM profile use increases concern because the source says exposure exists regardless of settings. Treat this as a service availability risk for F5-managed applications. Prioritize validation on internet-facing or business-critical virtual servers, then follow F5 guidance for remediation. Mitigation focus: Inventory BIG-IP versions and modules against the affected 13.0.0 and 12.1.x ranges.; Review F5 advisory K34514540 for vendor-approved fixes or mitigations.; Prioritize externally reachable virtual servers using HTTP profiles or APM profiles..
