CVE-2021-27215
CVSS V2 High 7.5
CVSS V3 Critical 9.8
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.
