Open Redirect vulnerabilities were found in libapache2-mod-auth-openidc, OpenID Connect Relying Party implementation for Apache, which could lead to information disclosure via phishing attacks.

CVE-2021-39191

The 3rd-party init SSO functionality of mod_auth_openidc was reported to be vulnerable to an open redirect attack by supplying a crafted URL in the target_link_uri parameter.

CVE-2022-23527

When providing a logout parameter to the redirect URI, mod_auth_openidc failed to properly check for URLs starting with /\t, leading to an open redirect.

For Debian 10 buster, these problems have been fixed in version 2.3.10.2-1+deb10u3.

We recommend that you upgrade your libapache2-mod-auth-openidc packages.
