Descriptions

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.

El módulo "OpenID Connect Relying Party and OAuth 2.0 Resource Server" (también conocido como mod_auth_openidc) en versiones anteriores a 2.1.6 para el servidor HTTP de Apache no omite cabeceras OIDC_CLAIM_ y OIDCAuthNHeader en una configuración "AuthType oauth20", lo que permite a atacantes remotos eludir autenticación a través de tráfico HTTP manipulado.

It was found that mod_auth_openidc did not properly sanitize HTTP headers for certain request paths. A remote attacker could potentially use this flaw to bypass authentication and access sensitive information by sending crafted HTTP requests.
