would of course help identify the server type and version. The second probe
would be useful in identifying servers running FrontPage Server Extensions
(FPE) and in directing an attack on a server that had tried to use security
through obscurity by moving the extensions to another directory.
This is not a directory traversal attempt. The _vti_inf.html contains
directory locations and client configuration information for FPE. It was not
an accidental connection attempt by a FrontPage client, because it swept the
Alternative explanations about how this probe might help an attacker?
