Name of the Vulnerable Software and Affected Versions mpGabinet versions prior to 23.12.20

Description mpGabinet performs client-side authentication, which is a process where the verification of user credentials happens on the user's device rather than the server. An attacker with access to any application instance connected to the backend server can bypass the login verification process by manipulating the application binary to authenticate as an arbitrary user.

Recommendations Update to a version later than 23.12.19.
