CVE-2022-32434Public exploitNetwork attack vector

Process crash via out-of-bounds message read

Published Jul 15, 2022 · Updated Aug 3, 2024

A stack-buffer overflow in EIPStackGroup OpENer 2.3.0 allows attackers to crash the process with a crafted incoming message. The POSIX executable reads one byte beyond the 512-byte incoming_message stack buffer, and AddressSanitizer aborts at frame offset 560. Triggering the demonstrated condition requires a valid EtherNet/IP session and the project's testcase sender; public evidence demonstrates a crash, not code execution.
