CVE-2025-55910Public exploitNetwork attack vector

Arbitrary file deletion via incomplete path sanitization

Published Sep 19, 2025 · Updated Sep 19, 2025

Path traversal in CMSEasy 7.7.8.0 and earlier allows remote attackers to delete arbitrary server files through database_admin.php. The backAll_action method removes traversal substrings only once, then passes the resulting backup-relative path to unlink(). Exploitation requires user interaction; successful deletion can destroy application data or interrupt the hosted site.
