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, UPSTREAM_USER, UPSTREAM_PASSWORD, ADMIN_MAIL_ADDRESS, and ADMIN_PASSWORD parameters 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 these values are provided in the corresponding parameters. The values 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 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 certain parameters (TLS_HOSTNAME, UPSTREAM_USER, UPSTREAM_PASSWORD, ADMIN_MAIL_ADDRESS, and ADMIN_PASSWORD) when adding a new DNS entry. The injected code is stored and later executed in the web interface when other users view the affected DNS configuration, potentially compromising their session or data.

Impact Analysis

This vulnerability can allow an attacker to execute malicious JavaScript code in the context of other users who view the affected 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.
