#Privilege Escalation in RedaxScript 2.1.0  
  
  
RedaxScript 2.1.0 suffers from a privilege Escalation vulnerability. The  
issue occurs because the application fails to properly implement access  
controls. The application also fails to perform proper sanity checks on the  
user supplied input before processing it. These two flaws led to a  
vertical privilege escalation. This can be achieved by a simply tampering  
the parameter values. An attacker can exploit this issue to gain elevated  
privileges to the application.  
  
*Steps to reproduce the instance:*  
  
· login as a non admin user  
  
· Go to account and update the account.  
  
· intercept the request and add “*groups[]=1*” to the post data and  
submit the request  
  
· Log out of the application and log in again. You can now browse  
the application with admin privileges.
