[Full-disclosure] HTTP 404 - Content-Type: image/gif

["Joshua Tagnore" <joshua.tagnore@xxxxxxxxx>]

Hi list !,

   While performing a pentest I found the following:

mafo:/home/joshua/$ nc XXXXX 80 -v -v
GET http://www.XXXXXX.com/YYYYYY HTTP/1.0


HTTP/1.0 404 Not Found
Date: Fri, 17 Nov 2006 13:40:47 GMT
Content-Length: 0
Content-Type: image/gif
Server: Apache/2.0.54 (Unix)

   The thing to notice here is the "Content-Type: image/gif" header
returned by the server. The requests that return this header are all
requests that dont end in .html ; for example
http://www.XXXXXX.com/f00.htmlwill return a normal header, but
http://XXXXXX.com/bar.txt will return a "Content-Type: image/gif". Does
anyone have a clue about this configuration ? What is it for ?

Cheers,
