ZZCMS 2025 CVE-2025-14836

Immediate remediation requires upgrading ZZCMS to a patched version addressing cleartext storage in /reg/user_save.php; however, no vendor-released patch version is identified in available data-contact ZZCMS vendor directly for updates or security advisories. As a compensating control pending patch availability, restrict direct file system access to /reg/user_save.php output directories via operating system permissions (chmod/ACLs), allowing only the web server process and administrators read access; this limits exposure if files are exposed via directory traversal or backup leaks. Additionally, implement encryption for stored user data at the application level by modifying the User Data Storage Module to hash passwords using bcrypt or PBKDF2 and encrypt personal information fields using AES-256; note this requires code-level changes and database schema review. For immediate operational risk reduction, disable or restrict access to the user registration endpoint (/reg/user_save.php) to trusted networks only using firewall or web server rules (IP whitelisting in .htaccess or nginx config), trading user self-service registration capability for security while development proceeds. Monitor disk storage locations for unauthorized access using file integrity monitoring (e.g., auditd on Linux, Windows File Auditing) to detect if plaintext data is read.
