Administrator file upload via missing type validation
Published Sep 25, 2023 · Updated Apr 22, 2025
Arbitrary file upload in Prevent Files / Folders Access before 2.5.2 allows remote authenticated users to upload files to the server. The mo_media_restrict_page handler accepts uploads without validating file types, including PHP content. Administrator-level access is required, and uploaded scripts can enable remote code execution or compromise confidentiality, integrity, and availability.
