  and spoof an arbitrary https site by letting a browser obtain a valid certificate.");

  script_tag(name:"insight", value:"The following vulnerabilities exist:

  - Error in processing a '3xx' HTTP CONNECT response before a successful SSL
  handshake, which can be exploited by modifying the CONNECT response
  to specify a 302 redirect to an arbitrary https web site.

  - Error exists while the HTTP Host header to determine the context of a
  document provided in a '4xx' or '5xx' CONNECT response from a proxy server,
  which can be exploited by modifying this CONNECT response, aka an
  'SSL tampering' attack.

  - Displays a cached certificate for a '4xx' or '5xx' CONNECT response page
  returned by a proxy server, which can be exploited by sending the browser a
  crafted 502 response page upon a subsequent request.

  - Detects http content in https web pages only when the top-level frame uses
  https. This can be exploited by modifying an http page to include an https
  iframe that references a script file on an http site, related to
  'HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages.'");
