/.ssh/Authorized_keys is public php
<p>When I open <code>http://mysite.com/.ssh/authorized_keys</code> a page opens and has the following information:                                          </p>

<blockquote>

<p>What is this? And is this Vulnerable? Can an attacker gain Admin privilege with it? If so, what will he do? How will he do an attack?</p>

<p>Version: PHP/5.3.18</p>
