Code execution via crafted DVP file

Published Jan 18, 2024 · Updated Jun 17, 2025

Heap buffer overflow in Delta Electronics ISPSoft 3.02.11 allows remote attackers to execute code via a crafted DVP file. The public advisory identifies DVP-file handling but does not disclose the parser routine, malformed field, or copy operation that overruns the heap buffer. Exploitation requires a user to open the file, after which code executes in the application's security context.
