What is CVE-2021-42342?
An identified issue in the GoAhead web server versions 4.x and 5.x prior to 5.1.5 allows user form variables to be passed to CGI scripts without proper prefixing. This oversight enables attackers to tunnel untrusted environment variables into affected CGI scripts, potentially leading to unauthorized access and exploitation of the server's functionality.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
