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 pienumber parameter when updating the default firewall IP search values. When a user updates these defaults, the application issues an HTTP POST request to /cgi-bin/logs.cgi/firewalllogip.dat with the default number of IPs in the pienumber parameter. The value of this parameter is 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 page.

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 via the 'pienumber' parameter when updating the default firewall IP search values. The injected script is stored and later executed in the web interface when other users view the affected page, due to lack of proper input sanitization or encoding.

Impact Analysis

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