CVE-2024-1925Network attack vector

Authenticated dangerous-file upload via Upsys.php

Published Feb 27, 2024 · Updated Aug 8, 2024

Unrestricted file upload in Ctcms 2.1.2 allows remote authenticated users to place dangerous files through the Upsys.php controller. The public record identifies ctcms/apps/controllers/admin/Upsys.php as the affected locus but does not disclose the upload parameter or missing validation operation. Low-privileged network access is required, and successful exploitation permits attacker-controlled file content to reach the server.
