The software does not adequately validate input given in the macFilterType and deviceList parameters. If an attacker sends an unusually large amount of data to these parameters, they can overflow the buffer, causing the system to crash or, in some cases, allowing the attacker to execute arbitrary code or gain unauthorized access.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2716798407\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here is a conceptual example of how the vulnerability might be exploited in a HTTP POST request:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/formSetMacFilterCfg HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n&quot;macFilterType&quot;: &quot;AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...&quot;,\n&quot;deviceList&quot;: &quot;BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB...&quot;\n}<\/code><\/pre>\n<p>In this example, &#8220;A&#8221; and &#8220;B&#8221; represent an overflow of data that exceeds the buffer&#8217;s capacity.
