Details:  
========  
1.1  
Multiple persistent input validation vulnerabilities are detected in the NetBill v1.2 web application.  
The bugs   
allow remote attackers to implement/inject malicious script code on the application side (persistent).   
  
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent)   
context manipulation.   
Exploitation requires low user inter action.  
  
Vulnerable Module(s):  
  
[+] /accounts/admin/index.php?user=59902561 - user Full Name  
[+] /accounts/admin/index.php?user=59902561 - add file (Title - Description)  
[+] /accounts/index2.php?page=support - Inject via support request (Details)

1.2  
A cross site request forgery vulnerability is detected in in NetBill v1.2 web application. The bugs allow remote attackers with   
high required user inter action to edit user accounts. Successful exploitation can lead to account creation. To exploit   
the issue the attacker need to create a manipulated copy the edit user mask/form. Inside of the document the remote   
can implement his own values for the update because of no form or token protection. When admin get now forced to execute   
the script via link he is executing the new value on the update of the application if his session is not expired.  
  
Vulnerable Module(s):  
  
[+] /accounts/admin/index.php?action=new-client - Add New Account

Risk:  
=====  
1.1  
The security risk of the persistent input validation vulnerability is estimated as medium.  
  
1.2   
The security risk of the cross site request forgery vulnerability is estimated as low(+).
