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

The vulnerability is caused due to the "updateFile()" function in
inc/core/class.dc.media.php script not properly verifying uploaded
file types. This can be exploited to execute arbitrary PHP code by
uploading a PHP file.

Successful exploitation requires "manage their own media types"
permissions.

The vulnerability is confirmed in version 2.2.2. Prior versions may
also be affected.

SOLUTION:
Update to version 2.2.3.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Raphael.
