Title: XSS + Info leak @ www.myownemail.com
Date: 22.03.02
Author: elab (http://elaboration.8bit.co.uk)
Problem: Cross site scripting problems as well as web root exposure
Vendor Status: Contacted on: 16:00 GMT 12 March 02
Via: msp () myownemail com
Response: None
Summary:
Certain script variables in certain URLs at MOE owned web sites
can be replaced with a scripting language like JavaScript. When
an unknowing user clicks on such a URL the JS will be executed.
Below is a copy of the email that was sent to the vendor
(contact address was taken from the help link @
www.mystartingpage.com).

Hey guys,
I found a few problems that you might want to be made aware of.
http://www.mystartingpage.com/default.cfm?p=
http://trust-me.com/moe4/mail/ReadMessage.cfm?num_messages=&message=04&domain=trust-me.com&UID=[hash]&CurrentFolder=inbox&cb=045
The second one I left my UID hash out of but it needs a valid hash to work. The first also reveals your web root.
I refer you to http://www.wiretrip.net/rfp/policy.html.

Post contacting the vendor a third problem was found:
http://www.myownemail.com/moe4/login/mailpassword.cfm?username=&domain=trust-me.com
Due to lack of response from vendor no attempt was made to
inform them of this third problem.
Solution:
None as of release date.
Vendor:
The vendor was contacted via msp () myownemail com on 16:00 GMT 12
March 02 and failed to respond.
CC'ed a copy of this advisory.
Notes:
MOE seem to use a one way hash to authenticate their users.
This seems to take the form of a 302 Object Moved which
redirects the client to a URL containing a UID hash calculated
server side. Little, if any information is contained in the
cookies issued by the server which lessens the impact of the
above issues.
Also, the web root exposure is likely due to the version of the
scripting engine they are using, rather than a problem with
their scripts.
