CVE-2022-38355Network attack vector

Unauthenticated information disclosure over local networks

Published Dec 13, 2022 · Updated Apr 16, 2025

Improper access control in Daikin SVMPC1 2.1.22 and earlier and SVMPC2 1.2.3 and earlier allows remote attackers to disclose stored data. The published advisory does not identify the affected endpoint, request, or access-control operation that exposes the stored sensitive information. An attacker needs LAN access but no authentication; the documented impact is limited to reading information from the controller.
