eScan 5.5-2 Web Management Console Command Injection

Vulnerability Description

A command injection vulnerability exists in the eScan Web Management Console version 5.5-2. The application fails to properly sanitize the 'pass' parameter when processing login requests to login.php, allowing an authenticated attacker with a valid username to inject arbitrary commands via a specially crafted password value. Successful exploitation results in remote code execution. Privilege escalation to root is possible by abusing the runasroot utility with mwconf-level privileges.
