HTTP: Tinyproxy HTTP Connection Headers Use-After-Free
This signature detects attempts to exploit a known vulnerability against Tinyproxy. A successful attack can lead to arbitrary code execution.
Extended Description
A use-after-free vulnerability exists in the HTTP Connection Headers parsing in Tinyproxy 1.11.1 and Tinyproxy 1.10.0. A specially crafted HTTP header can trigger reuse of previously freed memory, which leads to memory corruption and could lead to remote code execution. An attacker needs to make an unauthenticated HTTP request to trigger this vulnerability.
