Summary

Red Hat Security Advisory: Red Hat Single Sign-On 7.4.6 security update on RHEL 6

Severity

Low

Notes

Topic: New Red Hat Single Sign-On 7.4.6 packages are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Low. 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 7.4 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 6 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.

CVE-2020-7676

A XSS flaw was found in nodejs-angular. The regex-based input HTML replacement may turn sanitized code into unsanitized one. Wrapping "\<option\>" elements in "\<select\>" ones changes parsing behavior, leading to possibly unsanitizing code.

5.4 (Medium)

CVE-2020-14302

A flaw was found in Keycloak, where an external identity provider, after successful authentication, redirects to a Keycloak endpoint that accepts multiple invocations with the use of the same "state" parameter. This flaw allows a malicious user to perform replay attacks.

CVE-2020-7676 (GCVE-0-2020-7676)

Vulnerability from cvelistv5 – Published: 2020-06-08 13:34 – Updated: 2024-08-04 09:41

Summary

angular.js prior to 1.8.0 allows cross site scripting. The regex-based input HTML replacement may turn sanitized code into unsanitized one. Wrapping "<option>" elements in "<select>" ones changes parsing behavior, leading to possibly unsanitizing code.

Severity ?

No CVSS data available.
