PhpMyAdmin Scripts 2.11.x before 2.11.9.5 and 3.x before 3.1.3.1 are susceptible to a remote code execution in setup.php that allows remote attackers to inject arbitrary PHP code into a configuration file via the save action. Combined with the ability to save files on server, this can allow unauthenticated users to execute arbitrary PHP code.
