A Stack Buffer Overflow issue was discovered in VIPA Controls WinPLC7 5.0.45.5921 and prior. A stack-based buffer overflow vulnerability has been identified, where an attacker with a specially crafted packet could overflow the fixed length buffer. This could allow remote code execution.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
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.
