Synopsis

The remote CentOS host is missing one or more security updates for mod_auth_openidc.

Description

The remote CentOS Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the mod_auth_openidc-2.4.9.4-2.el9 build changelog.

- open redirect by supplying a crafted URL in the target_link_uri parameter (CVE-2021-39191)

- mod_auth_openidc is an OpenID Certified authentication and authorization module for the Apache 2.x HTTP server. Versions prior to 2.4.12.2 are vulnerable to Open Redirect. When providing a logout parameter to the redirect URI, the existing code in oidc_validate_redirect_url() does not properly check for URLs that start with /\t, leading to an open redirect. This issue has been patched in version 2.4.12.2. Users unable to upgrade can mitigate the issue by configuring mod_auth_openidc to only allow redirection when the destination matches a given regular expression with OIDCRedirectURLsAllowed. (CVE-2022-23527)

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 CentOS 9 Stream mod_auth_openidc package.
