    multiple scripts that allows a remote attacker, via a
    specially crafted request, to disclose the software's
    installation path. (CVE-2016-2044)

  - A cross-site scripting vulnerability exists due to
    improper validation of user-supplied input to the SQL
    editor. An authenticated, remote attacker can exploit
    this, via a specially crafted SQL query, to execute
    arbitrary script code in a user's browser session.

instead relied only on the application's self-reported version number.");
