Assigner: VulnCheck

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 UPDATE_VALUE parameter when updating the default time synchronization settings. When the default values displayed on the Time Server page are updated, the application issues an HTTP POST request to /cgi-bin/time.cgi, and the synchronization value is provided in the UPDATE_VALUE 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 Time Server configuration page.

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 via the UPDATE_VALUE parameter when updating the default time synchronization settings. The injected script is stored and later executed in the context of other users who view the affected Time Server configuration page, because the application does not properly sanitize or encode the input.

Impact Analysis

This vulnerability can allow an attacker to execute malicious JavaScript code in the browsers of users who view the affected Time Server configuration page. This can lead to unauthorized actions performed on behalf of those users, theft of sensitive information such as session tokens, or other malicious activities within the context of the affected web interface.
