What is CVE-2023-50094?

The vulnerability in reNgine, prior to version 2.1.2, permits OS Command Injection due to improper handling of user input within the application. When an attacker with a valid session ID manipulates the API endpoint at api/tools/waf_detector/?url=, they can insert shell metacharacters, which leads to arbitrary command execution with root privileges. This flaw exposes systems to potential severe consequences, as it allows unauthorized commands to be executed via subprocess.check_output, thereby compromising system integrity and security.

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.
