Stack-based buffer overflow in the GoAhead Web Server on Schneider Electric Modicon M340 PLC BMXNOx and BMXPx devices allows remote attackers to execute arbitrary code via a long password in HTTP Basic Authentication data.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
