Description

On BIG-IP FPS, ASM, and Advanced WAF versions 16.1.x before 16.1.1, 15.1.x before 15.1.4, and 14.1.x before 14.1.4.4, an XML External Entity (XXE) vulnerability exists in an undisclosed page of the F5 Advanced Web Application Firewall (Advanced WAF) and BIG-IP ASM Traffic Management User Interface (TMUI), also referred to as the Configuration utility, that allows an authenticated high-privileged attacker to read local files and force BIG-IP to send HTTP requests. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
