Overview

Signum DVB-S/S2 IRD Authentication Bypass

Multiple Elber products are affected by an authentication bypass vulnerability which allows unauthorized access to the password management functionality. Attackers can exploit this issue by manipulating the endpoint to overwrite any user's password within the system.

This grants them unauthorized administrative access to protected areas of the application, compromising the device's system security.
