CVE-2022-41653Network attack vector

Unauthenticated credential disclosure via exposed password file

Published Dec 13, 2022 · Updated Apr 16, 2025

Credential disclosure in Daikin SVMPC1 2.1.22 and earlier and SVMPC2 1.2.3 and earlier allows remote attackers to obtain login passwords. A web request can read files in a specific controller directory, including a file that stores the SVM login password. Access requires a position on the controller's LAN; the recovered credentials permit authenticated equipment operation and control-setting changes.
