Submit #259243: gopeak MasterLab ≤v3.3.10 Post-Auth File Uploadinfo

Titlegopeak MasterLab ≤v3.3.10 Post-Auth File Upload
DescriptionA critical file upload vulnerability was discovered in the MasterLab platform, specifically within the update function of the app/ctrl/admin/User.php file, which affects versions up to v3.3.10. The vulnerability, identified by glzjin, allows attackers to execute remote code by uploading a malicious avatar image encoded in base64 format. The flaw lies in the improper handling of file extensions within the UploadLogic::base64ImageContent method, which trusts the file type declared in plaintext. Attackers exploiting this vulnerability can gain unauthorized access and potentially take control of the affected server, making it a severe security risk that requires immediate attention and patching.
