    Description
    
    ***********
    
    Zone-h Security Team has discovered a serious security flaw in QShop v2.5 
    (and older versions?). This storefront system allows remote 
    administration for an online shopping system. The remote administration 
    usually is in the directory /qshop/admin.
    
    Details
    
    *******
    
    Q-Shop is an ASP shopping cart / storefront system that covers all the 
    needs for ecommerce web sites. Q-Shop is not just a shopping cart but a 
    full online shop system including web based shop administration.
    
    In the remote administration there is a script that allows the 
    administrator to add images, text etc. on the webserver. This page is by 
    default located at: /qshop/admin/upload.htm . This page is reachable 
    without authentication. Using this sample upload script it is possible 
    for a remote attacker to upload files like ntdaddy.asp, cmd.asp, 
    explore.asp on the webserver gaining full access to the webserver.
    
    
    Solution:
    
    *********
    
    The vendor has been contacted and a patch is not yet produced
    
    
    Suggestions:
    
    ************
    
    Delete the upload procedure.
