Red Hat Security Advisory: mod_auth_openidc security update
Severity
Low
Notes
Topic: An update for mod_auth_openidc is now available for Red Hat Enterprise Linux 7.
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: The mod_auth_openidc is an OpenID Connect authentication module for Apache HTTP Server. It enables an Apache HTTP Server to operate as an OpenID Connect Relying Party and/or OAuth 2.0 Resource Server.
Security Fix(es):
* mod_auth_openidc: Open redirect in logout url when using URLs with leading slashes (CVE-2019-14857)
* mod_auth_openidc: Open redirect issue exists in URLs with slash and backslash (CVE-2019-20479)
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.
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.9 Release Notes linked from the References section.

An open redirect flaw was discovered in mod_auth_openidc, where it handles logout redirection. The module does not correctly validate the URL, allowing a URL with leading slashes to bypass the protection checks. A victim user may be tricked into visiting a trusted vulnerable web site, which would redirect them to another possibly malicious URL.

Threats
Impact
Low
An open redirect flaw was discovered in mod_auth_openidc where it handles logout redirection. The module does not correctly validate the URL, allowing a URL with slash and backslash at the beginning to bypass the protection checks. A victim user may be tricked into visiting a trusted vulnerable web site, which would redirect him to another, possibly malicious, URL.
