Description Andrej Nemec 2017-03-03 09:05:24 EST

The "OpenID Connect Relying Party and OAuth 2.0 Resource Server" (aka mod_auth_openidc) module for the Apache HTTP Server does not skip OIDC_CLAIM_ and OIDCAuthNHeader headers in an "AuthType oauth20" configuration, which allows remote attackers to bypass authentication via crafted HTTP traffic.
