Dell Secure Connect Gateway contains a missing authentication vulnerability that allows unauthenticated, remote attackers to gain unauthorized access to critical functions.

Executive summary

A critical authentication bypass vulnerability in Dell Secure Connect Gateway allows unauthenticated remote attackers to potentially compromise the security of the application.

Vulnerability

This flaw is classified as a missing authentication for critical function (CWE-306). It allows an unauthenticated attacker with network access to interact with sensitive administrative or functional endpoints without providing valid credentials.

Business impact
