Summary

On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, 12.1.x before 12.1.5.3, and 11.6.x before 11.6.5.3, a malicious HTTP response to an Advanced WAF/BIG-IP ASM virtual server with Login Page configured in its policy may trigger a buffer overflow, resulting in a DoS attack. In certain situations, it may allow remote code execution (RCE), leading to complete system compromise. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
