CVE-2022-36361Network attack vector

Remote code execution via malformed TCP packets

Published Oct 11, 2022 · Updated Nov 20, 2024

Classic buffer overflow in Siemens LOGO! 8 BM and SIPLUS LOGO! 8 BM devices allows remote attackers to execute custom code. Several TCP-processing methods fail to validate packet structure before copying input, allowing buffer overflows and instruction-counter control. No authentication or user interaction is required; network access to the affected TCP services exposes confidentiality, integrity, and availability.
