D-Trust: Missed Revocation of TLS certificates affected by Bugzilla 1884714

RESOLVED FIXED D-TRUST
AI Summary

D-Trust issued TLS certificates containing an LDAP-URL in the Subscriber Certificate Authority Information Access field after September 15, 2023. Upon discovery, D-Trust revoked 2,601 affected certificates within five days. However, four certificates issued on January 26 and March 1, 2024, went undetected during the mass revocation. The root cause was identified as communication issues between the Nexus CM and CSM, which were not detected during testing. D-Trust has since implemented measures to prevent future occurrences, including an error-tolerant data synchronization system.
