Keycloak < 24.0.5 Unauthorized Access (CVE-2024-3656)

high Nessus Plugin ID 200516

Language:

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

In Keycloak prior to 24.0.5, users with low privileges (just plain users in the realm) are able to utilize administrative functionalities within Keycloak admin interface. This issue presents a significant security risk as it allows unauthorized users to perform actions reserved for administrators, potentially leading to data breaches or system compromise.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade Keycloak to 24.0.5 or later.
