CVE-2022-1161

An attacker with the ability to modify a user program may change user program code on some ControlLogix, CompactLogix, and GuardLogix Control systems. Studio 5000 Logix Designer writes user-readable program code to a separate location than the executed compiled code allowing an attacker to change one and not the other. Additionally, devices communicating over the unauthenticated version of EtherNet/IP may be vulnerable to attacks from custom clients exploiting CVE-2021-22681 .
