I'm guessing that you tested a server wth some kind of customized 404
response that neglected to include a charset specification. That's
not a vulnerability in Apache, that is poor site configuration.
Brian, a question for clarification. When you say "customized 404
response", you are not referring to a customized error document (as
described briefly in the httpd.conf file) but rather to having changed the
headers that the server returns when queried with a GET request, correct?
And wouldn't this require changing source code and compiling a custom
build of apache?
I am referring to the customized error documents described in the
httpd.conf file. No recompiling required.
The default Apache response for 404s includes a content-type header
specifying the iso-8859-1 charset. If you set up an ErrorDocument
handler, though, Apache assumes you know what you are doing and does
not include a charset specification in the content-type header. You
need to do it yourself. Including a meta http-equiv tag in the HTML
seems like an obvious fix, but there are other ways as well.
