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 Ubuntu. See How to fix? for Ubuntu:19.04 relevant fixed versions and status.

A vulnerability was found in mod_auth_mellon before v0.14.2. An open redirect in the logout URL allows requests with backslashes to pass through by assuming that it is a relative URL, while the browsers silently convert backslash characters into forward slashes treating them as an absolute URL. This mismatch allows an attacker to bypass the redirect URL validation logic in apr_uri_parse function.
