Hi,
The term "Cookie Poisoning" usually refers to the act of manipulating
cookie values (in one's own HTTP session) in order to perform illegal
actions (e.g. SQL Injection, Session Hijacking, etc.), in web
applications that rely on cookie values, but do not properly validate
these values.
You can find a whitepaper on this subject in our web site:
https://www.watchfire.com/securearea/whitepapers.aspx?id=18
In addition, the following link presents additional information on
Cookie Poisoning:

ing.html
XSS attacks may enable a malicious user to steal cookies from other
users, as well as perform many other things through the injection of
malicious client-side scripts (e.g. JavaScript, VBScript, etc.)
Hope this helps,

Subject: Cookie poisoning without XSS
I was reading about cookie poisoning. I want to know if there is any way
we can poision cookies if XSS vulnerability is not possible.
As far as I know, only in the presence of an XSS vulnerability, cookies
can be modified. Can anyone describe a method of cookie poisoning even
without XSS.
Small code snippets would be very helpful to me.
Smith
