CVE-2023-5263Network attack vector

Authenticated unspecified impact via backup restoration

Published Sep 29, 2023 · Updated Jun 18, 2025

Permission issues in ZZZCMS 2.1.7 allow remote authenticated users to cause unspecified impacts via crafted database-restore requests. The restore function in /admin/save.php mishandles undisclosed input while processing backup files; public records do not identify the faulty permission operation. Low-privileged access to the network-exposed handler is required, and the documented consequences remain limited to unspecified confidentiality, integrity, and availability effects.
