Overview

Affected versions of this package are vulnerable to Out-of-bounds Read in the CIP message parsing process when handling malformed explicit requests with a forged path_size field. An attacker can cause the system to read beyond the end of the stack receive buffer by sending a valid ENIP SendRRData frame with a CIP payload whose path_size claims more path words are present than actually exist.
