Published Jun 7, 2023 · Updated Jan 6, 2025

Stack-based buffer overflow in Delta Electronics CNCSoft-B DOPSoft before 4.0.0.82 allows remote attackers to execute arbitrary code. The DOPSoft executable copies user-supplied DPA file data into a stack buffer without first validating its length. Exploitation requires the target to open a malicious DPA file or visit a malicious page, and code runs in the current process context.
