The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1862 advisory.
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 7.6.8 on RHEL 9 serves as a replacement for Red Hat Single Sign-On 7.6.7, and includes bug fixes, security updates and enhancements which are linked to in the References.
Security Fix(es):
* Authorization Bypass (CVE-2023-6544)
* Log Injection during WebAuthn authentication or registration (CVE-2023-6484)
* path transversal in redirection validation (CVE-2024-1132)
* unvalidated cross-origin messages in checkLoginIframe leads to DDoS (CVE-2024-1249)
* undertow: Out-of-memory Error after several closed connections with wildfly-http-client protocol (CVE-2024-1635)
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.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
