Code execution via unchecked DPAX stack copy
Published Sep 24, 2025 · Updated Sep 24, 2025
Stack-based buffer overflow in Delta Electronics CNCSoft-G2 before 2.1.0.34 allows attackers to execute code via a crafted DPAX file. The DOPSoft component copies an unchecked length of DPAX data into a fixed-length stack buffer, corrupting adjacent stack memory. Exploitation requires a user to visit a malicious page or open the file and yields code execution in the current process.
