X02/XB1 in Logs - Hack on Site?

[palmpal]

Hello,

I've noticed a 414 error in my logs recently where someone is trying to access x02/xb1 . . . . and it keeps repeating. The error says the URI is too large and that this may be an indication that someone is trying to hack my site. I run Faststats analyzer. Does anyone here know anything about this syntex and what it means?

Thanks!

This is an unchecked buffer exploit attempt. The attempt to overflow your input buffer failed, because the request was rejected by your server.
