SwissSign: MPKI step-up process sets wrong JoI Locality
SwissSign AG reported a mis-issuance of 18 Extended Validation (EV) certificates due to incorrect jurisdiction of incorporation (JoI) locality fields during a walkthrough of their MPKI step-up process. This issue was identified during an audit review session, and all affected certificates have since been revoked. The mis-issuance was attributed to a failure in the user interface and backend checks that should have prevented the entry of locality information for organizations registered at the state level. SwissSign has implemented corrective actions and enhanced their procedures to prevent similar issues in the future.
