DigiCert: Subject Serial Numbers for Non-Commercial Entities

DigiCert · RESOLVED
AI Summary

A Certificate Problem Report was filed against DigiCert regarding discrepancies in the `Subject:serialNumber` field of EV certificates issued to Non-Commercial Entities. The investigation revealed that DigiCert's validation workflow allowed agents to revert to a generic identifier instead of using a specific identifier that was previously validated. As a result, 384 certificates were affected, leading to the revocation of 374 certificates and the expiration of 10 others. DigiCert has since implemented changes to their workflow to prevent similar issues in the future.
