DESCRIPTION:
A vulnerability has been discovered in TYPO3, which can be exploited
by malicious people to compromise a vulnerable system.

Input passed to the "BACK_PATH" parameter in
typo3/sysext/workspaces/Classes/Controller/AbstractController.php is
not properly verified before being used to include files. This can be
exploited to include arbitrary files from remote resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability is confirmed in version 4.6.1. Prior versions may
also be affected.

SOLUTION:
Update to version 4.6.2.

PROVIDED AND/OR DISCOVERED BY:
