| عنوان | Krayin Krayin CRM ≤ 2.2.5 Broken Access Control |
|---|
| الوصف | Krayin CRM 2.2.5 contains an Insecure Direct Object Reference (IDOR) vulnerability in the email attachment download functionality. The vulnerability exists in the GET /admin/mail/attachment-download/{id} endpoint, where the application retrieves email attachments using a user-controlled numeric identifier without performing proper authorization checks. An authenticated low-privileged user can manipulate the attachment ID to access files belonging to other users, including attachments stored on the application's private filesystem. The issue is caused by missing object-level authorization validation, combined with insufficient route permission enforcement, allowing unauthorized disclosure of sensitive documents such as contracts, invoices, and confidential email attachments. Successful exploitation requires only a valid authenticated account and knowledge or enumeration of attachment identifiers. |
