phpMyAdmin: Local file inclusion vulnerability

Background

phpMyAdmin is a tool written in PHP intended to handle the administration of MySQL over the web.

Description

Maksymilian Arciemowicz reported that in libraries/grab_globals.lib.php, the $__redirect parameter was not correctly validated. Systems running PHP in safe mode are not affected.

Impact

A local attacker may exploit this vulnerability by sending malicious requests, causing the execution of arbitrary code with the rights of the user running the web server.

Workaround

Run PHP in safe mode.

Resolution

All phpMyAdmin users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-db/phpmyadmin-2.6.4_p2"
