<div class="faq">

|
<p class="question">On some sites I see a lot of "Connection from.."
|
|
entries that never complete.</p>
|
|
|
|
<p> This is probably because the page requests resources from SSL-protected
|
|
domains. These requests are intercepted by mitmproxy, but because we're
|
|
using a bogus certificate, the browser-side of the connection hangs. The
|
|
browser doesn't prompt you to add a certificate trust exception for remote
|
|
page components, only for the primary domain being visited. </p>
|
|
|
|
<p> To solve this, use something like FireBug to find out which page
|
|
components are hanging. Visit the relevant domains using your browser, and
|
|
add a certificate trust exception for each one. </p>
|
|
|
|
|
|
<p class="question">I'm pentesting an non-browser app that checks SSL
|
|
certificate validity. How do I make it trust the MITMProxy certificate?</p>
|
|
|
|
|
|
<p> Here's a quick and easy procedure you can use for Windows 7, as long as
|
|
the app in question uses the global Windows certificate repository. </p>
|
|
|
|
<ul>
|
|
|
|
<li> First copy the file <b>libmproxy/resources/bogus_template</b>
|
|
from the MITMProxy source, and edit it to include your target domain in
|
|
the CN parameter. The result should look like this:
|
|
|
|
<pre>[ req ]
|
|
prompt = no
|
|
distinguished_name = req_distinguished_name
|
|
|
|
[ req_distinguished_name ]
|
|
C = NZ
|
|
ST = none
|
|
L = none
|
|
O = none
|
|
OU = none
|
|
CN = target.domain.com
|
|
emailAddress = none</pre>
|
|
</li>
|
|
|
|
<li> Next, use your bogus template to generate a certificate, and
|
|
install it for MITMPRoxy to use:
|
|
|
|
<pre>openssl req -config ./my_bogus_template -x509 -nodes -days 9999 -newkey rsa:1024 -keyout mycert -out mycert
|
|
|
|
cp mycert ~/.mitmproxy/cert.pem</pre>
|
|
</li>
|
|
|
|
<li> Fire up MITMProxy, and configure Firefox on the Windows box to use
|
|
it. Browse to the target domain, and you should see a big warning about
|
|
an untrusted certificate. Use Firefox to export the certificate ("Add
|
|
Exception", "Get Certificate", then "View", tab to "Details" and click
|
|
"Export"). </li>
|
|
|
|
<li> From the command console, fire up <b>certmgr</b>. Select "Trusted
|
|
Root Certification Authorities", then on the top menu, "Action", "All
|
|
Tasks", and "Import". When prompted, select the certificate file you've
|
|
just saved from Firefox.</li>
|
|
|
|
<li> And that's it - your certificate should now be trusted for that
|
|
domain. Happy pentesting.</li>
|
|
|
|
</ul>
