DCShop vulnerability

We have seen several Web shops using your 
DCShop product as E-commerce system, where it is 
possble for unauthorized persons via a Web browser 
to retrieve customer creditcard numbers in cleartext. 
Athough the developers on their Web site 
recommends not to use the beta product for 
commercial use, we have found sites already using it 
commercially.

The issue does not show up on properly configured 
servers, i.e. where the "Everyone"-group has "Full 
Access" to the CGI-BIN or sub-folders, more info 
below.


The requests are made of the following URL:
http://theTargetHost/cgi-bin/DCShop/Orders/orders.txt
This will triger the Web host to send a text file with all 
recent orders, including the end-users name, 
shipping and billing-address, e-mail address AND 
CREDIT CARD NUMBERS with exp-dates.


It is also in some cases possible to find the 
administrator name and password in another text file 
from an URL:
http://theTargetHost/cgi-
bin/DCShop/Auth_data/auth_user_file.txt

We have reported this issue to the developer, 
DCscripts.com, who within hours posted a security 
issue bulletin on their web site to clarify the 
recommendations for their software:
