  Cibleclick.com Stores Passwords in Clear Text inside Cookies
------------------------------------------------------------------------

SUMMARY

 <http://www.cibleclick.com/> Cibleclick is a French affiliate program
based on banner exchange. Cibleclick offers personalized services
including stats, banner choice, etc. These services are based on a
login/password authentication. To provide better service they also utilize
cookies. The vulnerability is caused by the fact that the password is
stored in clear text inside the cookies.

DETAILS

This is a sample of an Cibleclick cookie:
CIBLE_CLICK_IDENT_ID
my_session_id
www.cibleclick.com/
0
3546759168
32088942
2512385488
29489647
*
PASSWORDD
my_password
www.cibleclick.com/

In this example, my_session_id and my_password are the session ID and
password in clear text. Retrieving the cookie is possible to anyone with
access to the cookies.txt file, to anyone utilizing a man-in-the-middle
attack, or by utilizing several browser vulnerabilities that allow remote
sites to retrieve cookies that were not provided by them.

Solution:
The solution is to use session ID, and never stores the passwords in the
cookies. The vendor has been informed and has not solved the problem.
