CVE-2023-40145Network attack vector

Authenticated command execution via HMI maintenance CGI

Published Oct 19, 2023 · Updated Jan 16, 2025

OS command injection in Weintek cMT3000 HMI Web CGI firmware allows remote authenticated users to execute arbitrary commands. The affected locus is among the web server's miscellaneous HMI-maintenance scripts, but Weintek has not disclosed which CGI script passes request data into an OS command. Network access and a low-privilege session are required; successful exploitation permits command execution on the HMI appliance.
