Damn. Disabled ours for now, has this been confirmed? Does just putting the system into Maintenance mode make it 'safe'?

Yes, this is confirmed.  After seeing the... utterly incompetant coding practices, I wouldn't trust just using Maintenance mode.  I ripped down our entire install and just put up a placeholder for now.

Mind if I nick your parts of your maintenance message? Too tired to think of something decent.

Surely best to put a html message up?

RewriteCond %{QUERY_STRING} AES_ENCRYPT

RewriteRule ^(.+) /sorry.html [L]

 

 

This helps? Not sure if %{QUERY_STRING} would catch POST data or what would be the correct variable for that.

Didn't know if the exploit was real or not - why spend 5 minutes on an error page when you might remove it in an hour. But it looks like this is real, so I’m going to make a page. But either way, people aren't going to care why it is down.

I added the following on top of my .htaccess

Code:
Order allow,deny
Allow from 127.0.0.1 # for email piping to work
Allow from x.x.x.x # my VPN IP
Deny from all

Wonder how long it'll take WHMCS. Hope they aren't thinking "we'll fix it monday". Lot of lost business.
