Summary

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. 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.

Risk Assessment

An attacker could execute arbitrary JavaScript in other users' browsers, potentially leading to session theft, account takeover, or data modification.

Recommendation

Update IPFire to version 2.29 (Core Update 198) or later. Additionally, consider implementing XSS protection mechanisms such as Content Security Policy.

Original NVD description (English source)

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.
