CVE-2022-2866

Code execution via malformed FPJ project file

Published Aug 31, 2022 · Updated Apr 16, 2025

Out-of-bounds write in FATEK Automation FvDesigner 1.5.103 and earlier allows attackers to execute arbitrary code via a crafted FPJ project file. The FPJ parser fails to validate user-supplied data before writing past the end of an allocated data structure. Exploitation requires a valid user to open the malicious project file, and successful execution runs in the context of the FvDesigner process.
