CVE-2024-47135

Code execution via malformed PLC project data

Published Oct 3, 2024 · Updated Oct 3, 2024

Stack-based buffer overflow in JTEKT KPP 1.6.14.0 and earlier allows attackers to execute code via a crafted project file. Processing invalid PLC data in the KPP project-file parser writes beyond a stack buffer when the file is opened. A user must open a file created by KPP 1.6.9.0 or earlier; exploitation can also disclose information or crash the application.
