ZH2003-2SA (security advisory): QShop priviledge escalation Published: 09/07/2003
Name: QShop priviledge escalation
Affected Systems: QShop v2.5 (and older versions?)
Issue: Remote attackers can obtain full access to the remote system
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.
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.
The vendor has been contacted and a patch is not yet produced
Delete the upload procedure.
