F5: Security Vulnerabilities
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.

On BIG-IP (AFM, PEM) 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, 12.1.0-12.1.4, 11.6.1-11.6.3.4, and 11.5.1-11.5.8, an undisclosed TMUI pages for AFM and PEM Subscriber management are vulnerable to a stored cross-site scripting (XSS) issue. This is a control plane issue only and is not accessible from the data plane. The attack requires a malicious resource administrator to store the XSS.
