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

The vulnerability is caused due to an input validation error in the
processing of file uploads. This can be exploited to upload arbitrary
scripts by defining an invalid value for the "Type" parameter when
uploading a file via "editor/filemanager/upload/php/upload.php".

Successful exploitation requires that file uploads have been enabled
in the "config.php" configuration file (not enabled by default).

The vulnerability has been confirmed in version 2.2. Prior versions
may also be affected.

SOLUTION:
The vulnerability has been fixed in version 2.3 Beta.
