Unauthenticated code execution via multipart value overflow

Stack-based buffer overflow in Deep Sea Electronics DSE855 1.1.0 allows remote attackers to execute arbitrary code over an adjacent network. The multipart form-variable copying loop fails to verify remaining space in a fixed-length stack buffer and stops only upon a carriage return. No authentication is required, and overflowing the containing stack object can replace function pointers that are later dereferenced in the device context.
