CVE-2017-6413 (opens in a new tab)How to fix?
Upgrade Centos:7 mod_auth_openidc to version 0:1.8.8-5.el7 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mod_auth_openidc package and not the mod_auth_openidc package as distributed by Centos.
See How to fix? for Centos:7 relevant fixed versions and status.
The "OpenID Connect Relying Party and OAuth 2.0 Resource Server" (aka mod_auth_openidc) module before 2.1.6 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.
