Short explanation
Admidio before 5.0.10 suffers from an authorization bypass in file_delete, allowing authenticated users with upload rights to delete files in restricted folders. The vulnerability remains exploitable in 5.0.9 and was fully resolved in 5.0.10. Patch status is UNKNOWN; upgrade to 5.0.10 is required for mitigation.
This vulnerability enables unauthorized file deletion across folders, leading to data loss and potential breach of confidentiality. It affects users who rely on Admidio for secure file management and highlights the need for timely patching. No official patch status is confirmed; users must upgrade to 5.0.10 to mitigate risk.
What should be done?
- Upgrade to Admidio version 5.0.10 or later
- Do not use versions prior to 5.0.10
- Follow vendor advisory for patch details
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
Chain of evidence and sources
Admidio 5.0.10'ın önceki sürümlerinde, bir klasörde yükleme yetkisi olan kimlik doğrulamış kullanıcılar, yalnızca görüntüleme erişimine sahip klasörlerdeki dosyaları kalıcı olarak silme yetkisi kazanır, çünkü file_delete işlevinde yetki doğrulama eksikliği mevcuttur.
Açık, modules/documents-files.php dosyasındaki bir yetki doğrulama hatası nedeniyle ortaya çıkar; saldırıcının sağladığı folder_uuid parametresiyle yükleme yetkisi değerlendirilirken, gerçek ana klasör belirlenmez.
Açık, 5.0.9 sürümünde hâlâ istismar edilebilir ve 5.0.7 sürümünde kısmen düzeltilmiştir; tam düzeltme 5.0.10 sürümünde sunulmuştur.
Show the technical text from the sources
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.
