CVE-2022-21209

Code execution via FPJ bounds read

Published Feb 25, 2022 · Updated Apr 16, 2025

FvDesigner through 1.5.100 allows remote attackers to execute arbitrary code via a crafted FPJ project file. The FPJ parser fails to validate attacker-controlled lengths before reading past an allocated buffer, allowing code execution in the current process. Exploitation requires the target to open the malicious project file or visit a page that causes the file to be opened; no network service exposure is required.
