Eric,
There are multiple answers to you question depending on what you're trying
to do.
If you are trying to restrict access so that uploaded files cannot be
accessed in any way except through MediaWiki, you may want to read:
http://www.mediawiki.org/wiki/Manual:Image_Authorisation
If you just want to create a non-executable directory that is not part of
the web root, look up:
$wgUploadPath
$wgUploadDirectory
You may also want to take a look at:
$wgFileExtensions - do not allow server executables such as php, asp, pl,
etc.
$wgEnableUploads = false; # disallow uploads altogether
$wgGroupPermissions['*']['upload'] = false; # Disallow anonymous users
uploads
$wgGroupPermissions['*']['reupload'] = false;
$wgGroupPermissions['*']['reupload-shared'] = false;
$wgGroupPermissions['*']['minoredit'] = false;
# Disallow logged in users access, until you approve their ability to upload
$wgGroupPermissions['user']['upload'] = false;
$wgGroupPermissions['user']['reupload'] = false;
$wgGroupPermissions['user']['reupload-shared'] = false;
# Allow only approved accounts to upload
$wgGroupPermissions['approved']['upload'] = true;
$wgGroupPermissions['approved']['reupload'] = true;
$wgGroupPermissions['approved']['reupload-shared'] = true;

Subject: [Mediawiki-l] Upload security
I still want to make the system as safe as possible so that a hacker can
never upload anything malicious and run it. Our server was compromised but
that was through someone who was using an unsafe CMS.
Is there anything like, setting the Uploads directory to a directory that
is outside the WWW root, so even if a hacker uploads a scipt, he cant run it
using the browser, because its not accessible?
And also I guess we should set the permissions of that directory to be
non-executable, but writebable by all?
