Description Vincent Danen 2013-04-24 21:47:16 UTC
phpMyAdmin can be configured to save an export file on the web server, via its SaveDir directive. With this in place, it's possible, either via a crafted filename template or a crafted table name, to save a double extension file like foobar.php.sql. In turn, an Apache webserver on which there is no definition for the MIME type "sql" (the default) will treat this saved file as a ".php" script, leading to remote code execution.

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. Moreover, the SaveDir directive is empty by default, so a default configuration is not vulnerable. The $cfg['SaveDir'] directive must be configured, and the server must be running Apache with mod_mime to be exploitable.

This is fixed via the following commits:
