Technical details

A directory traversal vulnerability (CWE-35) exists in an undisclosed iControl REST endpoint within F5 BIG-IP. The vulnerability is specifically present when the device is running in 'Appliance mode'. An authenticated attacker with administrator-level privileges can exploit this flaw via the network to traverse the file system and delete arbitrary files. This allows the attacker to cross a security boundary that should normally restrict such file operations in Appliance mode. The issue affects multiple BIG-IP modules including LTM, APM, and AFM across versions 16.1.x, 17.5.x, and 21.0.0.
