Detailsinfo

A vulnerability classified as problematic was found in IPFire up to 2.28. This vulnerability affects an unknown functionality of the file /cgi-bin/urlfilter.cgi of the component Web Interface. The manipulation of the argument QUOTA_USERS with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79.

As an impact it is known to affect integrity. CVE summarizes:

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 QUOTA_USERS parameter when creating a user quota rule. When a user adds a new user quota rule the application issues an HTTP POST request to /cgi-bin/urlfilter.cgi with the MODE parameter set to USERQUOTA and the assigned user(s) provided in the QUOTA_USERS 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 quota entry.

The attack can be initiated remotely. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059.007 by the MITRE ATT&CK project.
