Information disclosure via crafted project file parsing
Published Mar 25, 2022 · Updated Apr 16, 2025
Out-of-bounds read in Delta Electronics CNCSoft 1.01.30 and earlier allows attackers to disclose information via a crafted project file. The project-file parser reads beyond a buffer boundary when processing a specifically malformed file; Delta has not identified the affected routine or field. Exploitation requires user interaction to open the file, exposing process-accessible data and potentially interrupting the application.
