CVE-2020-24672Network attack vector

Unauthenticated code execution via crafted SoftController message

Published Sep 8, 2021 · Updated Sep 17, 2024

Missing authorization and input validation in ABB Base Software for SoftControl 6.1 and earlier allow remote attackers to execute code. The SoftController processes specially crafted network messages without validating access or input data, permitting arbitrary code insertion. The SoftController must be running and network-reachable; injected code runs with the privileges of the user who launched it.
