CVE-2017-6062 (opens in a new tab)How to fix?
Upgrade Echo:latest libapache2-mod-auth-openidc to version 2.1.5-1 or higher.
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 Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
The "OpenID Connect Relying Party and OAuth 2.0 Resource Server" (aka mod_auth_openidc) module before 2.1.5 for the Apache HTTP Server does not skip OIDC_CLAIM_ and OIDCAuthNHeader headers in an "OIDCUnAuthAction pass" configuration, which allows remote attackers to bypass authentication via crafted HTTP traffic.
