Authorization Bypass Through User-Controlled Key
Kentico CMS before 13.0.66 has an Insecure Direct Object Reference vulnerability. It allows an attacker with user management rights (default is Administrator) to export the user options of any user, even ones with higher privileges (like Global Administrators) than the current user. The exported XML contains every option of the exported user (even the hashed password).
CWE-639 - Authorization Bypass Through User-Controlled Key
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
