medium Nessus Plugin ID 148019

Synopsis

The remote Red Hat host is missing one or more security updates for Red Hat Single Sign-On 7.4.6.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:0969 advisory.

Red Hat Single Sign-On 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 7.4.6 on RHEL 8 serves as a replacement for Red Hat Single Sign-On 7.4.5, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.

Security Fix(es):

* nodejs-angular: XSS due to regex-based HTML replacement (CVE-2020-7676)

* keycloak: reusable state parameter at redirect_uri endpoint enables possibility of replay attacks (CVE-2020-14302)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, 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.

Solution

Update the RHEL Red Hat Single Sign-On 7.4.6 package based on the guidance in RHSA-2021:0969.
