<p>SIMATIC S7-1200 CPU V1/V2 controllers contain two vulnerabilities that could allow an unauthenticated remote attacker</p>
<ul>
<li>to trigger functions by record and playback of legitimate network communication, or</li>
<li>to place the controller in stop/defect state by causing a communications error.</li>
</ul>
