CVE-2022-40202Network attack vector

Unauthenticated code execution via backup object deserialization

Published Oct 31, 2022 · Updated Apr 16, 2025

Missing authentication in Delta Electronics InfraSuite Device Master 00.00.01a and earlier allows remote attackers to execute arbitrary code. The database backup path deserializes attacker-supplied objects and lets ExeCommandInCommandLineMode schedule a chosen file with chosen arguments. No credentials or user interaction are required, and successful exploitation starts an arbitrary process with administrator privileges.
