CVE-2025-25223Network attack vector

Unauthenticated file disclosure via path traversal

Published Feb 18, 2025 · Updated Feb 18, 2025

Path traversal in LuxSoft LuxCal Web Calendar before 5.3.3M (MySQL) or 5.3.3L (SQLite) allows remote attackers to read server files. The dloader.php validation fails to confine a requested file path to the intended directory, so traversal sequences can select files elsewhere on the server. No authentication or user interaction is required, and exposure is limited to files readable by the web server process.
