Description

An issue was discovered in genua genugate before 9.0 Z p19 9.1.x through 9.6.x before 9.6 p7 and 10.x before 10.1 p4. The Web Interfaces (Admin Userweb Sidechannel) can use different methods to perform the authentication of a user. A specific authentication method during login does not check the provided data (when a certain manipulation occurs) and returns OK for any authentication request. This allows an attacker to login to the admin panel as a user of his choice e.g. the root user (with highest privileges) or even a non-existing user.
