Memory corruption via unchecked PRJ file bounds

Published Jun 17, 2025 · Updated Jun 4, 2026

Out-of-bounds write in LS Electric GMWIN 4.18 allows local users to corrupt memory through a crafted PRJ project file. The PRJ parser fails to validate user-supplied values before accessing allocated data structures, permitting reads and writes beyond their bounds. Exploitation requires a user to open the file and can disclose, alter, or corrupt process memory or crash the application.
