OpENer 2.3.0 (commit 76b95cf) has an out-of-bounds read issue in CIP message parsing when handling malformed explicit requests with a forged EPath size. An attacker can send a valid ENIP SendRRData frame carrying a very short CIP payload whose path size field claims that many more path words are present than are actually available. Because the parser trusts the attacker-controlled path size and continues decoding path segments without a remaining-length boundary, it reads beyond the end of the stack receive buffer.
