Detailsinfo

A vulnerability was found in Admidio up to 5.0.9. It has been classified as problematic. This affects an unknown code block of the file modules/documents-files.php of the component File Deletion. The manipulation of the argument folder_uuid with an unknown input leads to a improper authorization vulnerability. CWE is classifying the issue as CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on integrity, and availability. The summary by CVE is:

Admidio is an open-source user management solution. Prior to version 5.0.10, an authenticated Admidio member with upload rights on any one folder can permanently delete files from folders where they have only view access. The authorization check at the top of `modules/documents-files.php` evaluates upload rights against the attacker-supplied `folder_uuid` URL parameter — not the file's actual parent folder. The `file_delete` handler then only verifies view rights on the file's real location, never upload rights. By passing a folder they legitimately own in `folder_uuid` while targeting a file in a restricted folder via `file_uuid`, an attacker bypasses the upload-right check entirely and permanently deletes the file. This is an incomplete fix of GHSA-rmpj-3x5m-9m5f, which was patched in v5.0.7 but remains exploitable in v5.0.9. User should upgrade to v5.0.10 to receive an updated fix.
