Loaded Commerce Community

My car started to come up with errors and stopped clients going through to checkout, on investigation i have discovered a huge amount of code has appeared in the login.php file a small sample of which is below, how can I stop this vunerability.
I am on CRE Loaded6 v6.2 Standard White Label with patch:07

if you followed the security issues in 6.2

you need to have patched to no less than patch 12

But that isn't to say you were hacked from your script, but from somewhere else on the shared server you are on.. contact your host

and PATCH asap

Many thanks for your reply.
I have gone round in circles looking for the patches you recommend and can't find them anywhere, could you be kind enough to put a link to them here for me.

Thanks in advance

you download them from where you obtained the software

if it was here.. top left creloaded icon.. log in, and on the my account page, you will see downloads
