Overview
Affected versions of this package are vulnerable to Reliance on Undefined, Unspecified, or Implementation-Defined Behavior in the enipThread() function due to the lack of a return value. An attacker can cause the PLC process to crash and halt all automation or control logic by remotely triggering the server loop to end unexpectedly, such as by starting the same server multiple times or forcing the server to exit without authentication.
