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 IGNORE_ENTRY_REMARK parameter when adding a whitelisted host. When a whitelisted host is added, an HTTP POST request is sent to the Request-URI /cgi-bin/ids.cgi and the remark for the entry is provided in the IGNORE_ENTRY_REMARK parameter. The value of this parameter is stored and later rendered in the web interface without proper sanitization or encoding, allowing injected scripts to execute in the context of other users who view the affected whitelist entry.

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 via the IGNORE_ENTRY_REMARK parameter when adding a whitelisted host. The injected script is stored and later displayed in the web interface without proper sanitization, allowing the script to execute in the context of other users who view the affected whitelist entry.

Impact Analysis

The vulnerability can allow an attacker to execute malicious JavaScript code in the browsers of other users who view the affected whitelist entry. This can lead to session hijacking, unauthorized actions performed on behalf of users, or theft of sensitive information accessible through the web interface.
