Description

IPFire versions prior to 2.29 (Core Update 198) contain a command injection vulnerability that allows an authenticated attacker to execute arbitrary commands as the 'nobody' user via the BE_NAME parameter when installing a blacklist. When a blacklist is installed the application issues an HTTP POST to /cgi-bin/urlfilter.cgi and interpolates the value of BE_NAME directly into a shell invocation without appropriate sanitation. Crafted input can inject shell metacharacters, leading to arbitrary command execution in the context of the 'nobody' user.

Attack-Flow Graph

Executive Summary

This vulnerability is a command injection flaw in IPFire versions prior to 2.29 (Core Update 198). An authenticated attacker can exploit the BE_NAME parameter when installing a blacklist. The application uses the BE_NAME value directly in a shell command without proper sanitization, allowing the attacker to inject shell metacharacters and execute arbitrary commands as the 'nobody' user.

Impact Analysis

An attacker who successfully exploits this vulnerability can execute arbitrary commands on the affected system with the privileges of the 'nobody' user. This can lead to unauthorized actions, potential system compromise, and disruption of services.
