Unauthenticated code execution via multipart boundary overflow
Published Jun 13, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Deep Sea Electronics DSE855 1.1.0 allows remote attackers to execute arbitrary code via multipart requests. The web server's ExecMethod() routine copies an HTTP multipart boundary longer than 30 characters into a fixed-length stack buffer without a bounds check. Exploitation requires adjacent-network reachability but no authentication and overwrites function pointers that execute in the device context.
