An open redirect flaw was discovered in mod_auth_openidc where it handles logout redirection. The module does not correctly validate the URL, allowing a URL with slash and backslash at the beginning to bypass the protection checks. A victim user may be tricked into visiting a trusted vulnerable web site, which would redirect him to another, possibly malicious, URL.
The mod_auth_openidc is an OpenID Connect authentication module for Apache HTTP Server. It enables an Apache HTTP Server to operate as an OpenID Connect Relying Party and/or OAuth 2.0 Resource Server. Issues addressed include an open redirection vulnerability.
