A cookie can be changed by a program that runs on a client's computer and
modifies a cookie file. A HTTP proxy server can also modify cookie values
in transit. An IE BHO or toolbar can also change a cookie value via the
DOM. HTML applications can change a cookie value via the DOM too.

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
