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.

    - Resolves: rhbz#1626297 - CVE-2017-6413 mod_auth_openidc: OIDC_CLAIM and                                OIDCAuthNHeader not skipped in an 'AuthType oauth20'                                configuration [rhel-7]

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has mod_auth_openidc packages installed that are affected by multiple vulnerabilities:

  - 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. (CVE-2017-6413)

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Upgrade to latest upstream which fixes some CVEs

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
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)
