CubeCart 4.4.6 Open URL Redirection

`1. OVERVIEW  
  
CubeCart 4.4.6 and lower versions are vulnerable to Open URL Redirection.  
  
  
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 4.4.6 and lower versions contain a flaw that allows a remote  
cross site redirection attack. This flaw exists because the  
application does not properly sanitise the parameters, "r" and  
"redir". This allows an attacker to create a specially crafted URL,  
that if clicked, would redirect a victim from the intended legitimate  
web site to an arbitrary web site of the attacker's choice.  
  
  
4. VERSIONS AFFECTED  
  
4.4.6 and lower
