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 its a role but a user with this access role cannot perform the attack.
