CVE-2025-5952Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized upload filenames

Published Jun 10, 2025 · Updated Jun 10, 2025

OS command injection in ZendTo 6.10-6 Beta allows remote attackers to execute system commands through a crafted file upload. NSSDropoff.php passes attacker-controlled tmp_name values from uploaded files into two exec() calls without shell-safe validation or escaping. The upload path is remotely reachable without authentication, and successful injection runs commands with the web application process's privileges.
