IPFire Stored Cross-Site Scripting Vulnerability in Service Creation

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 through the PROT parameter while creating a new service. The injected script is executed in the context of users viewing the service entry, due to the application's failure to properly sanitize or encode the PROT parameter before rendering it.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of users viewing the affected service entry.

Reproduction

To reproduce this vulnerability, an authenticated user can create a new service and inject JavaScript into the PROT parameter. Once the service is saved, the injected script will execute when the service entry is viewed.

Remediation

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