Hi Jan,

We don't have a file called doc.php as part of CMS Builder. The attachment didn't come through, though. Could you try attaching the file again and we can take a look at it for you.

Thanks
Jason.

Hi,

This doesn't look like anything we've put together. As a precaution, you should do a search through your other .php files (cmsb files included) looking for references to "doc.php". Another option would be to do a backup of your data, and then re-upload CMS Builder to overwrite any references to the file that may have been put into CMS Builder.

Since it looks like your server was probably compromised, you can also contact your hosting provider with this information.

Hope this helps. Please let us know if you need anything else.

Do you have any other software on the server? Especially open-source software such as email scripts, wordpress, etc? It looks like it may be the result of an automated vulnerability scanner hacking your site.

I double-clicked on some random unique-looking content in the file ("2Qc0Hpyg2nrp9KjEQiyKGwqbjCeRy3ta2NDfiyqIcT2OVMNiIXLTdQW") and searched google and saw a number of results: http://www.google.com/search?q=2Qc0Hpyg2nrp9KjEQiyKGwqbjCeRy3ta2NDfiyqIcT2OVMNiIXLTdQW

Including this one: http://stackoverflow.com/questions/3328235/how-does-this-giant-regex-work

So it looks like this is an exploit that is commonly out there. I decoded some of the code and it looks like this particular script is called "Web Shell by oRb". You can read more about people being affected by it here:

Hope that helps!

Hi Dave, thanks for that, will do some more digging. I am surprised as this particular site is a cms builder only site - no wordpress or anything else like that - will double check if there is any other php code used for any special functions.

Hi Dave, does cms builder use phpThumb?

Hi Jan,

No, that's not part of the software or anything we use.
