CVE-2017-6413 (opens in a new tab)How to fix?
There is no fixed version for Debian:8 libapache2-mod-auth-openidc.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libapache2-mod-auth-openidc package and not the libapache2-mod-auth-openidc package as distributed by Debian.
See How to fix? for Debian:8 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.
