CVE-2021-40846Public exploitNetwork attack vector

Arbitrary code execution via cleartext update channel

Published Mar 4, 2022 · Updated Aug 4, 2024

Cleartext update transport in Rhinode Trading Paints 2.0.36 and earlier allows man-in-the-middle attackers to execute code. TP Updater.exe fetches version.xml and its listed binaries over HTTP, then executes a substituted binary from a trusted installation path without transport authentication. Attackers must redirect update traffic, and the victim must launch the updater and accept its UAC prompt for privileged execution.
