I have a nice little one (that's not a security risk - but it still shoulden't be allowed):
http://some.server.running.phpmyadmin/phpmyadmin/main.php3?lang=nl
That would actually set the language selection cookie in the browser - (and changing the langauge used later) - even though one diden't pass the adv. auth. request - then the errormessage will be shown in the language of your choise... This would in this case not be a problem - but if something like that happens other places in the code... that might end up be a problem...
;o)))
In other words - my opinion is never to trust any variable supplied on the GET (or a POST) request until at least the user is verified as a user with access rights... That would eliminate some future problems - but defenitly not all...

Some amazing things (you'll love them, Geert ;))
Let's say:
- you have three db (mysql of course, db1, db2) with an empty mysql.db table (no one should be the case but...)
- you use the advanced athentication mode,
- you log in as an user with $cfgServers[n]['only_db'] = 'db1' and $cfgAllowUserDropDatabase = TRUE
Then display database details, move to the end of the page, copy the url of the "delete db" link, paste it in your adress bar, replace db1 by db2 at this location and run the url... No problem to delete a db that is not your one :(
This kind of problem may be reproduced with nearly all actions since the script never checks whether the db to work on is in the list of allowed db or not :((
In advanced authentication mode, the script checks for allowed databases in $cfgServers[n]['only_db'] AND mysql.db, mysql.table. What to do if theses two sources are different?
Why does the script checks for allowed databases in mysql.db and mysql.table only in advanced authentication case.
To be continued....
