CVE-2020-16209Network attack vector

Remote code execution via unchecked memory transfer

Published May 19, 2022 · Updated Apr 16, 2025

Stack-based buffer overflow in FieldComm Group HART-IP Developer Kit 1.0.0.0 and hipserver 3.6.1 allows remote attackers to execute code. The hipserver IP interface performs an unchecked memory transfer from an oversized HART-IP client payload into an internal stack buffer. No authentication or user interaction is required; a crafted network message can take control of the server process or crash its host.
