<p>
    The random numbers generated could be predicted.
    The use of a predictable random value can lead to vulnerabilities when used in certain security critical contexts.
</p>

<h3>Risk</h3>

<p>

</p>

<h3>Vulnerable Code</h3>

<pre>
Random rnd = new Random();
byte[] buffer = new byte[16];
rnd.GetBytes(buffer);
return BitConverter.ToString(buffer);
</pre>

<h3>Solution</h3>

<pre>
using System.Security.Cryptography;

RandomNumberGenerator rnd = RandomNumberGenerator.Create();
</pre>
