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 SERVICE, LOGIN, and PASSWORD parameters when creating or editing a Dynamic DNS host. When a new Dynamic DNS host is added, the application issues an HTTP POST request to /cgi-bin/ddns.cgi and saves the values of the LOGIN, PASSWORD, and SERVICE parameters. The SERVICE value is displayed after the host entry is created, and the LOGIN and PASSWORD values are displayed when that host entry is edited. 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 or edit the affected Dynamic DNS entries.

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 SERVICE, LOGIN, and PASSWORD parameters when creating or editing a Dynamic DNS host. These parameters are saved 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 or edit the affected Dynamic DNS entries.

Impact Analysis

The vulnerability can allow an attacker to execute arbitrary JavaScript code in the browsers of other users who view or edit the affected Dynamic DNS entries. This can lead to session hijacking, theft of sensitive information, or performing actions on behalf of the victim user within the IPFire web interface.
