na klar findet google nix mit probfind - heisst ja auch propfind...
scheint so ein security-scan wie bei den formmailern oder den fp-extensions zu sein:
IIS 5.0 PROPFIND DOS #2
Systems affected:
IIS 5.0
Risk: Medium
Date: 6 May 2001
...
Description:
It is possible to remotely restart all IIS related services using specially crafted request.
If this request is repeated continously this seriously affects IIS performance.
Details:
Basically the problem are very long but valid propfind request containing lots of ":".
Demonstration:
--vv9.pl-------------------------------------------------------------------
#!/usr/bin/perl
...
---------------------------------------------------------------------------
Workaround: Disabling WebDav extensions may help
though I do not recommend using IIS on the Internet.
