An authorization bypass vulnerability exists in the Mavenir SCE Application Provisioning Portal, version PORTAL-LBS-R_1_0_24_0, which allows an authenticated 'guest' user to perform unauthorized administrative actions, such as accessing the 'add user' feature, by bypassing client-side access controls.
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.
