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 TLS_HOSTNAME parameter when adding a new DNS entry. When a user adds a DNS entry, the application issues an HTTP POST request to /cgi-bin/dns.cgi and the TLS hostname is provided in the TLS_HOSTNAME 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 DNS configuration.

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 TLS_HOSTNAME parameter when adding a new DNS entry. The injected script is stored and later executed in the web interface when other users view the affected DNS configuration, because the application does not properly sanitize or encode the TLS_HOSTNAME parameter.

Impact Analysis

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