CVE-2022-30228Network attack vector

Unauthorized request execution via missing CORS restrictions

Published Jun 14, 2022 · Updated Nov 12, 2025

Origin validation error in Siemens SICAM GridEdge (Classic) before 2.6.6 allows remote attackers to execute critical requests. The web server omits CORS restrictions for critical operations, allowing attacker-controlled cross-origin content to submit a malicious request. Exploitation requires a legitimate user to access an attacker-chosen resource; Siemens does not identify the affected endpoint or resulting operation.
