Hi!
My website is running Vbulletin 4.1.11 and it has been hacked yesterday.
it's just a deface, database is ok and all the cp is working.
I've tried to deleted forum.php and index.php and reupload them but no use

Here is my question:
- Is there any possible way to hack in to vbulletin with only deface.
- If there was sql injection, how can I check it

p/s: here is my website: 123-airsoft.info in case any of you want to see how it been deface


Regards
