  script_tag(name:"insight", value:"The flaw comes into play only on web servers that don't strip
  extraneous slashes from URLs, such as Apache 1.3.x, and allows a list subscriber, using a
  specially crafted web request, to retrieve arbitrary files from the server - any file accessible
  by the user under which the web server operates, including email addresses and passwords of
  subscribers of any lists hosted on the server. For example, if '$user' and '$pass' identify a
  subscriber of the list '$listname@$target', then the following URL:

  http://example.com/mailman/private/$listname/.../....///mailman?username=$user&password=$pass

  allows access to archives for the mailing list named 'mailman' for which the user might not
  otherwise be entitled.");
