r0t has discovered a vulnerability in DGNews, which can be exploited
by malicious users to compromise a vulnerable system.
Due to improper checks of file extensions in admin/upprocess.php it
is possible to upload arbitrary files to the "img" directory. This
can e.g. be exploited to upload and execute malicious PHP scripts.
Successful exploitation requires access to the administration
section.
The vulnerability has been confirmed in version 1.5. Other versions
may also be affected.

Edit the source code to ensure that file extensions are properly
checked.
