Assigner: VulnCheck

Description
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.

Executive Summary

IPCop versions up to and including 2.1.9 have an authenticated remote code execution vulnerability in their web-based administration interface. Specifically, the email configuration component improperly handles user input in the EMAIL_PW parameter by inserting it directly into system-level commands without sanitization. An authenticated attacker can exploit this by including shell metacharacters in the email password field and triggering a save-and-test-mail action, allowing them to execute arbitrary operating system commands with the privileges of the web interface, potentially leading to full system compromise.

Impact Analysis

This vulnerability can allow an authenticated attacker to execute arbitrary operating system commands on the affected IPCop system with the privileges of the web interface. This can lead to full system compromise, including unauthorized access, data theft, system manipulation, or disruption of services.
