Interesting entry in my web server logs. Someone has an infected/hacked computer..:-)

Here’s what I had in my error_log:

[Wed Jun 02 03:30:21 2004]
[error] [client 69.81.6.80] request failed: URI too long (longer than 8190)

A quick nslookup gave me:

Name:    user-12l21ig.cable.mindspring.com
Address:  69.81.6.80

The access_log had the following (abbreviated version):

69.81.6.80 - - [02/Jun/2004:03:30:21 -0400] "SEARCH /x90x02xb1x02xb1x02xb1x02

A quick wc -c showed that this crap goes on for 29231 characters!

Should I do something about it?

Update:

Thanks to Jason, I got this link which basically sums this entry up rather well:

“It is an IIS WebDAV exploit from April 2003 (?), apache is not affected, its just annoying :) (nachi and agobot use this exploit)”

Depends on whether your server can be manipulated or not

And if you don’t want it to polute your access log, then apply some filtering capability before it hits your server.

Otherwise, ignore it :p

Thanks for the link Jason. It sure helps to “know” what in the world it is. I will update my blog entry to reflect the link you gave.

It sure would be nice to keep it from polluting my log. Will try to play around with mod_rewrite settings and see if that helps.
