Echo: keycloak-25: security update to 25.0.6+e1org.keycloak:keycloak-quarkus-server: security update to 26.0.6

medium Tenable Cloud Security Plugin ID 457822

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A vulnerability was found in the Keycloak Server. The Keycloak Server is vulnerable to a denial of service
 (DoS) attack due to improper handling of proxy headers. When Keycloak is configured to accept incoming
 proxy headers, it may accept non-IP values, such as obfuscated identifiers, without proper validation.
 This issue can lead to costly DNS resolution operations, which an attacker could exploit to tie up IO
 threads and potentially cause a denial of service. The attacker must have access to send requests to a
 Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not
 overwrite incoming headers, and Keycloak is configured to trust these headers. (CVE-2024-9666)

Solution

Update the keycloak-25 library and its related packages to version 25.0.6+e1 or later.
