NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd24-mod_auth_mellon package and not the httpd24-mod_auth_mellon package as distributed by RHEL. See How to fix? for RHEL:7 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.
