CVE-2024-47131

Arbitrary code execution via unchecked DPA buffer copy

Published Nov 11, 2024 · Updated Nov 11, 2024

Stack-based buffer overflow in Delta Electronics DIAScreen before 1.5.0 allows attackers to execute code through a crafted DPA file. The DPA parser fails to validate attacker-controlled data length before copying BACnetObjectInfo data into a fixed-length stack buffer. A user must open the file in DIAScreen; successful exploitation runs arbitrary code in the current process.
