Global variables overwrite in "export.php".
The export script generates global variables from those present in the $_POST superglobal. This may lead to other exploits in the export script.
We consider this vulnerability to be serious.
This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users to access the required form.
phpMyAdmin versions 4.x (prior to 4.0.0-rc3).
Upgrade to phpMyAdmin 4.0.0-rc3 or newer.
