Code execution via unsanitized project file
Published Aug 31, 2022 · Updated Apr 16, 2025
Stack-based buffer overflow in Delta Electronics CNCSoft before 1.01.32 allows local users to execute code via a crafted project file. The project-file parser fails to sanitize input before writing it into a stack buffer, allowing attacker-controlled data to overflow the buffer. Exploitation requires a user to open the malicious file; the advisory describes local code execution rather than a remotely reachable service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
