Re: [Full-disclosure] Firefox: serious cookie stealing / same-do
This vuln is not exploitable in this condition against IIS server 6
and possibly earlier versions. IIS will die on the null character in
the new request. It doesn't seem like anyone has brought up this
fact.
Example (IIS): location.hostname='microsoft.com\x00www.coredump.cx';
Output:
microsoft.com returns '400 Bad Request.'.
Any input would be appreciated until the obvious patch comes out.
Regards,
base
