CVE-2024-25414Public exploitNetwork attack vector

Unauthenticated code execution through crafted ZIP upload

Published Feb 16, 2024 · Updated Mar 14, 2025

Arbitrary file upload in CSZ CMS 1.3.0 allows remote attackers to execute arbitrary code through a crafted ZIP archive. Public records identify /admin/upgrade as accepting the attacker-controlled archive, but they do not disclose the exact validation or extraction failure. Unauthenticated network access is sufficient, and successful exploitation can compromise application data and service availability.
