CVE-2025-47750

Code execution via crafted V7 or V8 files

Published May 19, 2025 · Updated May 19, 2025

Out-of-bounds write in Fuji Electric V-SFT 6.2.5.0 and earlier allows attackers to execute arbitrary code via a crafted V7 or V8 file. The VS6MemInIF!set_temp_type_default function writes beyond a memory buffer while parsing untrusted V7 or V8 file data. Exploitation requires a user to open the file; successful parsing can also disclose process data or crash the editor.
