<h2>Passing User Paramters to Systeminformation</h2>
<p>For most of the applications that are using <span class="code">systeminformation</span>, there is no reason to worry. <span class="bold">But be aware!</span> If you are using <span class="code">inetLatency()</span>, <span class="code">inetChecksite()</span>, <span class="code">services()</span>, <span class="code">processLoad()</span> with arbitrary untrusted user input, you should pay extra attention! We are doing a lot of input sanitation for those functions inside this package but we cannot handle all cases!</p>

<p class="warning">This can lead to serious impact on your servers!</p>
<p>We highly recommend to always upgrade to the latest version of our package. We maintain security updates for version 5 AND also version 4. For version 4 you can install latest version by placing <span class="code">"systeminformation": "^4"</span> in your package.json (dependencies) and run <span class="code">npm install</span></p>

</p>
<h4>Impact</h4>
<p>We had an issue that there was a possibility to perform a potential command injection possibility by passing a non string values as a parameter to the <span class="code">versions()</span>.</p>
<h4>Patch</h4>
<p>Problem was fixed with parameter checking. Please upgrade to version >= 4.34.20 if you are using version 4.</p>
<h4>Workarround</h4>
<p>If you cannot upgrade, be sure to check or sanitize parameter strings that are passed to <span class="code">versions()</span> (string only)</p>
