CVE-2022-23985

Code execution via unchecked FPJ file data

Published Feb 25, 2022 · Updated Apr 16, 2025

Out-of-bounds write in FATEK Automation FvDesigner 1.5.100 and earlier allows remote attackers to execute code through crafted FPJ files. The FPJ parser fails to validate user-supplied data before writing past the end of an allocated data structure. Exploitation requires the target to open a malicious file or visit a malicious page, and resulting code runs in the current process context.
