Description

IPFire versions prior to 2.29 (Core Update 198) contain a stored cross-site scripting (XSS) vulnerability that allows an authenticated attacker to inject arbitrary JavaScript code through the SRC, DST, and COMMENT parameters when creating a time constraint rule. When a user adds a time constraint rule the application issues an HTTP POST request to /cgi-bin/urlfilter.cgi with the MODE parameter set to TIMECONSTRAINT and the source hostnames/IPs, destination, and remark provided in the SRC, DST, and COMMENT parameters respectively. The values of these parameters are stored and later rendered in the web interface without proper sanitation or encoding, allowing injected scripts to execute in the context of other users who view the affected time constraint entry.

Attack-Flow Graph

Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in IPFire versions prior to 2.29 (Core Update 198). An authenticated attacker can inject arbitrary JavaScript code through the SRC, DST, and COMMENT parameters when creating a time constraint rule. These parameters are stored and later displayed in the web interface without proper sanitization or encoding, allowing the injected scripts to execute in the context of other users who view the affected time constraint entry.

Impact Analysis

The vulnerability can allow an attacker to execute arbitrary JavaScript code in the context of other users who view the affected time constraint entries. This can lead to unauthorized actions performed on behalf of those users, theft of sensitive information such as session tokens, or other malicious activities within the web interface.
