Several legacy features of the McAfee Enterprise Mobility Manager (EMM) Portal can possibly be used to execute man-in-the-middle attacks against EMM users.  Specifically:
  • The Login.aspx page does not disable browser Autocomplete support.
  • The About.aspx page displays excessive details for the “User Agent” and “Connection” string variables allowing for a possible Cross-Site Scripting (XSS) attack.
  • The About.aspx page displays the IIS user which the worker process is running as.
  • The ASP.NET Session Cookie is not marked with the Secure flag.

  • The IIS Request Filtering feature can be used to prevent access to the About.aspx page as it does not provide end-user functionality.
