The Palo Alto Networks security platform that provides intermediary services for TLS must validate certificates used for TLS functions by performing RFC 5280-compliant certification path validation.
Medium Severity
<VulnDiscussion>A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make an informed decision regarding acceptance of an end entity certificate.
Certification path validation includes checks such as certificate issuer trust, time validity and revocation status for each certificate in the certification path. Revocation status information for CA and subject certificates in a certification path is commonly provided via certificate revocation lists (CRLs) or online certificate status protocol (OCSP) responses.
The Palo Alto Networks security platform can be configured to use Open Certificate Status Protocol (OCSP) and/or certificate revocation lists (CRLs) to verify the revocation status of certificates and the device itself can be configured as an OCSP responder.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
