CVE-2022-47908

Code execution via crafted project-file stack overflow

Published Jan 3, 2023 · Updated Apr 10, 2025

Stack-based buffer overflow in Fuji Electric V-Server 4.0.12.0 and earlier allows local users to execute code via a crafted project file. Public advisories identify the project-file parser as the affected locus but do not disclose the field or copy operation that overruns the stack buffer. Exploitation requires a user to open the file and can also disclose information in the affected process context.
