My site has been hacked. It was my fault because I had weak permissions plus a script that allowed to upload images without any further verification. As a result of this I got a jpg that contained a shell script which got executed via RFI.

As countermeasures I secured the permissions, but I also disallowed any means of image uploading including vbulletin custom avatars, signatures, profilepics and user albums.

Perhaps I'm going too far so I wanted to ask. Are VB img upload scripts secured against gifs containing malicious php code?

If such a bug was reported it would be fixed and a new version would be issued. That's a rather big security hole so I'm sure a patch would come out very quickly.

As mentioned, RFI is a very big issue - and I'm sure the devs would have already looked at it. vBulletin itself should not be vulnerabvle to RFI, however, this does not always ring true for modifications.

It is not a VB3 engine, just a parsed copy!
