Delta UFC500 充電站 CVE-2026-22105：預設密碼可被重建
CVE-2026-22105 - Use of default password based on serial number
Delta UFC500 充電站的 Service 帳號預設密碼由序號字元推導，未授權攻擊者可在相鄰網路上重建或暴力破解，進而讀取或修改敏感設定，如 OCPP 後端。
此 CVE 讓電動車充電站的預設密碼可被重建，提醒業界須強化密碼策略與存取控制。
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.
