Notes

Topic
New Red Hat Single Sign-On 7.6.10 packages are now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat Single Sign-On 7.6 is a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications. This release of Red Hat Single Sign-On 7.6.10 on RHEL 8 serves as a replacement for Red Hat Single Sign-On 7.6.9, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix(es): * potential bypass of brute force protection (CVE-2024-4629) * session fixation in elytron saml adapters (CVE-2024-7341) * Leak of configured LDAP bind credentials through the Keycloak admin console (CVE-2024-5967) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

The LDAP testing endpoint allows changing the Connection URL\u00a0 independently without re-entering the currently configured LDAP bind credentials.

The Keycloak server will connect to the attacker\u0027s host and try to authenticate with the configured credentials, thus leaking them to the attacker. As a consequence, an attacker who has compromised the admin console or compromised a user with sufficient privileges can leak domain credentials and attack the domain.",
