		<description><![CDATA[<p>The management network be a private trusted network.</p>
<p>Anyway, here you are a workaround</p>
<p>1) Create a file with the following (you may name the file CVE-2011-3192):</p>
<p>httpd include &#8221;
# Drop the Range header when more than 5 ranges
# CVE-2011-3192
SetEnvIf Range (,.*?){5,} bad-range=1
RequestHeader unset Range env=bad-range&#8221;</p>
<p>2) bpsh &#60; CVE-2011-3192</p>
<p>3) bigstart restart httpd</p>
