Subject: [XSS] I found a xss in phpmyadmin 3.3.0 when we create new database
 in interface!

there is a xss in phpmyadmin 3.3.0 when we create new database in interface, the "new_db" parameter do not filter characters when users enter. attacker can enter malicious code, like "<script>alert(/liscker/);</script>". it also can be true in post and get. but in post, we can not encode xss code, or , the xss will faild. 

For example:

GET:

http://localhost/phpmyadmin/db_create.php?token=567eb60e7b1692f64df9251ab7ae3934&reload=1&new_db=%3Cscript%3Ealert%28%2Fliscker%2F%29%3B%3C%2Fscript%3E&db_collation=

POST:

POST /phpmyadmin/db_create.php HTTP/1.1

When you test, please replace the session "759f7a380111a292995ec447408bbdb3" with yourself. I suggest to test it in interface.
