Recently Rockwell Automation fixed a critical vulnerability (CVE-2018-14829) found in its RSLinx Classic, a software platform that allows Logix 5000 Programmable Automation Controllers to connect to a wide variety of Rockwell Software applications. A remote attacker could make the device being accessed stop responding and crash by sending a malicious CIP packet to Port 44818. This vulnerability also has the potential to exploit a buffer overflow condition, which may allow the threat actor to remotely execute arbitrary code.
