CubeCart 5.x Cross Site Request Forgery

`1. OVERVIEW  
  
CubeCart 5.x versions are vulnerable to Cross Site Request Forgery (CSRF).  
  
  
2. BACKGROUND  
  
CubeCart is an "out of the box" ecommerce shopping cart software  
solution which has been written to run on servers that have PHP &  
MySQL support. With CubeCart you can quickly setup a powerful online  
store which can be used to sell digital or tangible products to new  
and existing customers all over the world.  
  
  
3. VULNERABILITY DESCRIPTION  
  
CubeCart 5.x versions contain a flaw that allows a remote Cross-site  
Request Forgery (CSRF / XSRF) attack. The flaw exists because the  
application does not require multiple steps or explicit confirmation  
for sensitive transactions for majority of administrator functions  
such as adding new user, assigning user to administrative privilege.  
By using a crafted URL, an attacker may trick the victim into visiting  
to his web page to take advantage of the trust relationship between  
the authenticated victim and the application. Such an attack could  
trick the victim into executing arbitrary commands in the context of  
their session with the application, without further prompting or  
verification.
