CVE-2026-72556

A remote code execution vulnerability in ZoneMinder 1.39.17 allows any authenticated user to execute OS commands by exploiting a broken permission check in the Filter class. The canEdit() and canDelete() methods invoke nonexistent methods on the ZM\User class, causing PHP __call() to return a truthy value that bypasses the permission check for all users. Any authenticated user can trigger filter-based OS command execution regardless of their assigned role.

Summary		(es) Una vulnerabilidad de ejecución remota de código en ZoneMinder 1.39.17 permite a cualquier usuario autenticado ejecutar comandos del sistema operativo al explotar una verificación de permisos defectuosa en la clase Filter. Los métodos canEdit() y canDelete() invocan métodos inexistentes en la clase ZM\User, lo que provoca que PHP __call() devuelva un valor verdadero que omite la verificación de permisos para todos los usuarios. Cualquier usuario autenticado puede desencadenar la ejecución de comandos del sistema operativo basada en filtros independientemente de su rol asignado.
