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.

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2019-2112 advisory.

  - Mod_auth_openidc.c in the Ping Identity OpenID Connect authentication module for Apache (aka     mod_auth_openidc) before 2.14 allows remote attackers to spoof page content via a malicious URL provided     to the user, which triggers an invalid request. (CVE-2017-6059)

  - 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.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A text injection flaw was found in how mod_auth_openidc handled error pages. An attacker could potentially use this flaw to conduct content spoofing and phishing attacks by tricking users into opening specially crafted URLs.(CVE-2017-6059)

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.(CVE-2017-6413)
