CVE-2023-0123

Code execution via unchecked DPA data copy

Published Feb 2, 2023 · Updated Jan 16, 2025

Stack-based buffer overflow in Delta Electronics DOPSoft 4.00.16.22 and earlier allows attackers to execute code via a crafted DPA file. DPA file parsing copies user-supplied data into a stack buffer without first validating its length. Exploitation requires the current user to open the file or visit a malicious page, and code runs in the DOPSoft process context.
