Executive brief
Dell Secure Connect Gateway (SCG) is a network appliance used to provide secure remote access and gateway functionality for organizations. A flaw in certificate validation allows unauthenticated attackers on the network to bypass security checks and gain unauthorized access to the system. This could enable credential theft, session hijacking, or pivoting to other systems on the corporate network.
Technical details
The vulnerability is an improper certificate validation flaw affecting the authentication and encryption mechanisms in Dell SCG. An unauthenticated attacker with network access can exploit weak certificate validation to intercept or spoof encrypted communications.
