CVE-2021-4466

EIP tracks 1 public exploit for CVE-2021-4466. PoCs published by Mücahit Saratar.

AI-analyzed exploit summary This exploit leverages command injection in IPCop 2.1.9's email.cgi by embedding a command in the EMAIL_PW parameter, which is executed when a test email is sent. It requires authentication and sends two POST requests: one to save settings and another to trigger the command execution.

IPCop versions up to and including 2.1.9 contain an authenticated remote code execution vulnerability within the web-based administration interface. The email configuration component inserts user-controlled values, including the EMAIL_PW parameter, directly into system-level operations without proper input sanitation. By modifying the email password field to include shell metacharacters and issuing a save-and-test-mail action, an authenticated attacker can execute arbitrary operating system commands with the privileges of the web interface, resulting in full system compromise.
