Missing Release of Memory after Effective Lifetime
On BIG-IP 15.0.0-15.0.1, 14.1.0-188.8.131.52, 14.0.0-14.0.1, and 13.1.0-184.108.40.206, when a virtual server is configured with HTTP explicit proxy and has an attached HTTP_PROXY_REQUEST iRule, POST requests sent to the virtual server cause an xdata memory leak.
CWE-401 - Missing release of memory after effective lifetime (memory leak)
'Missing release of memory after effective lifetime (memory leak)' is a weakness that occurs when software doesn't effectively release allocated memory after it is used. If not addressed, this enables attackers to launch denial of service attacks (by crashing or hanging the program) or take advantage of other unexpected behavior resulting from low memory conditions.
