CVE-2022-1402

Code execution via malformed project file parsing

Published Apr 29, 2022 · Updated Apr 16, 2025

Out-of-bounds read in Delta Electronics ASDA-Soft 5.4.1.0 and earlier allows attackers to execute code via a crafted project file. The project-file parser fails to sanitize file-controlled input before using it in a memory read, allowing access beyond the intended buffer. Exploitation requires a user to open an attacker-supplied project file; CISA reports no remote path or known public exploit.
