Name of the Vulnerable Software and Affected Versions u5CMS versions prior to 3.9.4

Description The issue allows remote attackers to write to arbitrary files. This can be achieved by providing a (1) .. (dot dot) or (2) full pathname in the f parameter of the /u5admin/deletefile.php API endpoint.

Recommendations For versions prior to 3.9.4, update to version 3.9.4 or later to resolve the issue.

Avoid using the f parameter in the affected endpoint until the issue is resolved.
