| Title | gopeak MasterLab ≤v3.3.10 Post-Auth File Upload |
|---|
| Description | The described vulnerability in MasterLab's app/ctrl/admin/User.php file pertains to an insecure file upload mechanism within the add function. This function improperly handles base64-encoded image data for user avatars, accepting the file extension from the decoded content's MIME type without proper validation. An attacker with admin privileges can exploit this by uploading a malicious PHP script disguised as an avatar image. Upon execution, this script could potentially lead to unauthorized actions or access within the system, compromising its security. |
