 Scripts Effected: Thttpd Secure Webserver, and Mini_httpd Webserver

 If htaccess is used to password protect a directory, it is possible an
 attacker can access data behind the password protected area by knowing
 the name of the file he wants to view without a valid login. This also
 works on htpasswd files in general, which are protected by the webserver
 itself so that it cannot be readable by the web. A request like the one
 below will gladly feed the contents of a .htpasswd file.

 Couldn't reproduce the described behavior running thttpd 2.20b on freebsd
and linux (with and without chroot)

 Requesting any file before authenticating:

"Authorization required for the URL '/bar/foo.txt/'."
"Authorization required for the URL '/bar/.htpasswd/'."
"The requested URL '/bar/duh/' was not found on this server."
    Requesting .htpasswd after basic authentication:

"The requested URL '/bar/.htpasswd/' is an authorization file, retrieving it is

 Requesting unreadable file (mode 600) before authentication:

"The requested URL '/bar/foo.txt/' resolves to a file that is not world-readabl
