CVE-2021-27215: Genua Genuagate

Critical severity, CVSS 9.8. EPSS: 2.3% chance of exploitation in the next 30 days.

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.

Affected products

• Genua Genuagate: up to and including 9.0; from 10.0, up to and including 10.1; version 9.0 only; version 9.6.0 only; version 10.1 only
