Join us for an hour of Live Q&A at our PKI Solutions "Office Hours." - Impact & Action: Certificate Based Authentication Changes (KB5014754)
To address the threats from CVE-2022-34691, CVE-2022-26931 and CVE-2022-26923, Microsoft will enforce strong mappings between an authentication certificate and the account object with a new Object Identifier Extension (OID) 1.3.6.1.4.1.311.25.2. Microsoft is phasing in changes to how certificates are mapped to Windows accounts.
These changes will cause authentication failures with certificates issued using client authentication and not using Active Directory to supply subject information. ADCS CAs, non-ADCS CAs, Managed PKIs, Public CAs, and Standalone CAs will be impacted. These offline certificate requests are how all MDM issue certificates, including NDES and Intune. Smart Cards are often offline requests which will impact federal and civilian orgs using CAC and LACS cards.
If you are facing challenges with your PKI and have issues with the enforcement of these changes we are here to help.
