This blog post details a critical pre-authentication Remote Code Execution (RCE) vulnerability impacting CyberPanel versions up to 2.3.6 and the unpatched 2.3.7.
Vulnerability Analysis
The flaw resides in the `upgrademysqlstatus` function within `databases/views.py`. It allows attackers to bypass authentication and execute arbitrary commands as root due to the following factors:
– Security Middleware Bypass: The `secMiddleware` meant to protect against unauthorized access only functions for POST requests. This vulnerability leverages a GET request.
– Shell Metacharacter Injection: The attacker can inject shell metacharacters into the `statusfile` property to achieve code execution.
Exploitation and Impact
This vulnerability was actively exploited in October 2024 by the PSAUX ransomware group, potentially compromising a significant number of servers.
