This xss (with xsrf possibility) works only when logged in, but since in many places anonymous logins are allowed and many webhost companies offer just 1 or few phpmyadmins for a large number of users, i consider it worth to be published.

Theoretically it is possible to obtain and use the cookie and token variables (which are necessary to get this XSS working) but i haven't made a working poc atm, but i'm sure  others will have the capability to do so.

The problem is bad filtering of $db and $table where they only check for (lowercase) -tag and not for the (uppercase)-tag to break out of the javascript.

More details can be found in an advisory found here:
http://www.virtuax.be/advisories/Advisory2-24012007.txt 

possible attack strings could look like:
http://phpmyadmin.example.com/index.php?token=$token&db/table=';[XSS] 
http://phpmyadmin.example.com/index.php?token=$token&db/table=[HTML] 

in each case if you're running phpmyadmin <= 2.9 it's wise to update, stefan esser has even used phpmyadmin as an example in one of the bugs he found and reported in (his) mopb over a week ago(
