CFCA: ICA without EKU
The China Financial Certification Authority (CFCA) discovered that its Intermediate Certificate Authority (ICA), CFCA DV OCA, was issued without the Extended Key Usage (EKU) extension. This issue was reported on August 15, 2022, leading CFCA to review its certificate issuance process. CFCA revoked the problematic ICA on September 19, 2022, and implemented corrective measures, including the introduction of automated detection tools (Zlint) to prevent future occurrences. The CA has since completed the development and testing of these tools, ensuring that all certificates will be verified before issuance. The case has been resolved, and CFCA has applied for closure of the bug.
