Description

Rockwell Automation RSLinx Classic Versions 4.00.01 and prior. This vulnerability may allow a remote threat actor to intentionally send a malformed CIP packet to Port 44818, causing the software application to stop responding and crash. This vulnerability also has the potential to exploit a buffer overflow condition, which may allow the threat actor to remotely execute arbitrary code.

• CWE-121Stack-based Buffer OverflowA 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).
• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe 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.
