CVE-2020-16236

Code execution via out-of-bounds project read

Published Jan 25, 2021 · Updated Sep 16, 2024

Out-of-bounds read in Panasonic Control FPWIN Pro 7.5.0.0 and earlier allows attackers to execute arbitrary code via a crafted project file. The PRO-file parser fails to validate user-supplied data before reading past the end of an allocated data structure. A target must open the malicious file, after which code runs in the context of the FPWIN Pro process and can compromise the workstation.
