Published Oct 19, 2022 · Updated Apr 16, 2025
Write-what-where in Fuji Electric SX-Programmer Expert (D300win) before 3.7.1.17 allows remote attackers to overwrite program memory. The affected parser or input field is undisclosed; processing attacker-controlled input writes chosen values to chosen memory locations. Exploitation requires user interaction and can redirect program control; the CNA reports no confidentiality or availability impact.
