Unauthenticated service interruption via IP address manipulation
Published Oct 11, 2022 · Updated Oct 8, 2024
Improper input validation in Siemens LOGO! 8 BM and SIPLUS variants in all versions allows remote attackers to interrupt service. The device accepts an unauthenticated network interaction without the validation needed to protect its configured IP address. Exploitation changes the address and leaves the controller unreachable until it is power-cycled, with no reported confidentiality or data-integrity impact.
