CVE-2021-27215 : What You Need to Know
Discover the details of CVE-2021-27215, a vulnerability in genua genugate allowing unauthorized access to admin panels. Learn about the impact, affected versions, and mitigation steps.
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.
Understanding CVE-2021-27215
This section provides an insight into the vulnerability and its impact.
What is CVE-2021-27215?
CVE-2021-27215 is a security issue in genua genugate versions before 9.0 Z p19, 9.1.x through 9.6.x before 9.6 p7, and 10.x before 10.1 p4. It allows an attacker to gain unauthorized access to the admin panel through authentication manipulation.
The Impact of CVE-2021-27215
The vulnerability enables malicious actors to login as any user, including high-privileged users like the root user, by exploiting the authentication process in the Web Interfaces.
