CVE-2022-2253Network attack vector

Administrative OS command execution via command injection

Published Jul 1, 2022 · Updated Apr 16, 2025

OS command injection in Distributed Data Systems WebHMI 4.1.1.7662 allows remote authenticated users to execute commands on the host. Neither CISA nor the vendor has published the affected endpoint, parameter, or command-construction path. Administrative WebHMI privileges are required; successful exploitation runs attacker-supplied operating-system commands on the embedded host.
