Microsoft PKI Services: Improper Disclosure of CRLs – IDP – Existing CAs

RESOLVED FIXED Microsoft Corporation
AI Summary

Microsoft PKI Services (MPS) identified syntax issues with Certificate Revocation List (CRL) URLs in the CCADB while investigating improper CRL disclosures. The issue arose during the transition of existing CAs from full CRLs to partitioned CRLs, leading to a case mismatch between the URLs in CCADB and those in the CRLs. MPS has since updated the CCADB entries to ensure compliance with CCADB Policy Section 6.2. All action items related to this incident have been completed, and MPS has implemented measures to prevent recurrence.
