NVD Description

Note: Versions mentioned in the description apply only to the upstream libapache2-mod-auth-mellon package and not the libapache2-mod-auth-mellon package as distributed by Debian.

A vulnerability was found in mod_auth_mellon before v0.14.2. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication.
