Liz0ziM has reported a vulnerability in PHP Upload Center, which
potentially can be exploited by malicious people to compromise a
vulnerable system.

The vulnerability is caused due to an error in the handling of file
uploads where a filename has multiple file extensions. This can be
exploited to upload malicious PHP script files into the upload
directory inside the web root.

Example:
file.php.x

The vulnerability has been reported in version 1.4. Other versions
may also be affected.

SOLUTION:
Edit the configuration file to ensure that PHP script files are
correctly rejected or place the upload directory outside the web
root.
