| Can anyone identify this http exploit? Seen in the apache logs:
| 
| foo.bar.com
|  - - [30/May/2004:02:45:28 -0400] "SEARCH 
| /\x90\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\
| x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb
| 1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb

| etc - and it goes on for about 1200 bytes.

This is an older IIS WebDAV exploit.  More info at

You can mod_rewrite these attempts to /dev/null

RedirectMatch permanent (.*)\/x90\/(.*)$ /dev/null
