IPFire Stored Cross-Site Scripting Vulnerability in Dynamic DNS Functionality

A stored cross-site scripting vulnerability has been identified in IPFire versions prior to 2.29 (Core Update 198). This vulnerability allows authenticated attackers to inject arbitrary JavaScript into the web interface by exploiting the SERVICE, LOGIN, and PASSWORD parameters while creating or editing Dynamic DNS hosts. The injected scripts are executed in the context of users who view or edit the affected entries, due to the lack of proper sanitation or encoding before rendering these values in the web interface.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of users interacting with the Dynamic DNS entries.

Remediation

Users can update to IPFire 2.29 (Core Update 198) to address this vulnerability.
