CVE-2026-22105
Delta UFC500 charging stations derive the default credentials of the Service account from character positions of the device serial number.
Impact
Delta UFC500 charging stations derive the default credentials of the Service account from character positions of the device serial number. An unauthenticated attacker with adjacent network access can reconstruct the resulting password, or exhaust the keyspace, and log in to read and change sensitive settings such as the OCPP backend.
