"The remote host is running a version of EMC Documentum D2 that is
4.5.x or 4.6.x prior to 4.7. It is, therefore, affected by multiple
vulnerabilities :

  - A cross-site scripting (XSS) vulnerability exists due to
    improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted request, to execute arbitrary script
    code in a user's browser session. (CVE-2016-9872)

  - A Document Query Language (DQL) injection vulnerability
    exists due to a failure to properly sanitize
    user-supplied input. An authenticated, remote attacker
    can exploit this to inject or manipulate DQL queries in
    the back-end database, resulting in the manipulation or
    disclosure of arbitrary data. (CVE-2016-9873)");
