On BIG-IP (ASM) 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, and 12.1.0-12.1.4, Application logic abuse of ASM REST endpoints can lead to instability of BIG-IP system. Exploitation of this issue causes excessive memory consumption which results in the Linux kernel triggering OOM killer on arbitrary processes. The attack requires an authenticated user with role of "Guest" or greater privilege. Note: "No Access" cannot login so technically it's a role but a user with this access role cannot perform the attack.

Security readout for executives and security teams

CVE-2019-6637 is an authenticated denial-of-service risk in F5 BIG-IP ASM. A low-privileged logged-in user can abuse ASM REST endpoints enough to exhaust memory, causing Linux to terminate arbitrary processes and destabilize the BIG-IP system. Exposure is limited to organizations running the listed BIG-IP ASM versions with authenticated users able to access relevant ASM REST functionality. Risk increases where management access is broadly reachable or low-privileged accounts are widely issued. Treat as a bounded but real availability risk. Prioritize remediation for internet-facing or business-critical BIG-IP ASM appliances, especially where many administrators or delegated users have low-privileged access. Mitigation focus: Check F5 advisory K29149494 for vendor-confirmed fixes or workarounds.; Inventory BIG-IP ASM versions against the affected ranges.; Restrict BIG-IP management and REST access to trusted networks..
