-----BEGIN PGP SIGNED MESSAGE-----
ppp-design found the following cross-site-scripting bug in SunShop
Product: SunShop Shopping Cart
Version: 2.5 and maybe all versions before
OS affected: all OS with php and mysql
Vendor-Status: informed, patched
Security-Risk: high - very high
SunShop is a php/mysql based shopping system. Because it is a commercial
solution ($99.99) we could not have a look into the source code. All
impacts are tested in a demo shop on their website. SunShop is suffering
a cross-site-scripting bug because none of the user inputs seems to be
checked for malicious code.
When registering as a new customer, none of the inputs is checked for
stuff here, that is executed everytime the admin takes a look at the
customer listing in the admin area, which is protected by http
authentication. Together with some document.location.href stuff the
blackhat is now able to redirect the admin to any page in the admin
area. Because the admin is allready authenticated, the blackhat does not
need to have the admin's password. The redirection makes it possible to
do everything the admin can do, eg. generating new coupons.
Enter the following name when registering as a new customer:
code gets executed. Together with some more document.location.href the
blackhat is able to do anything the admin can.
We do not have the source code, so we cannot suggest any temporary fix.
Use the latest version.
Because a possible blackhat could nearly control the whole shop we rate
the security risk high - very high.
We have informed the vendor and he reacted very quickly. According to
his statement the bug is now fixed.
