multiple vulnerabilities.");

"According to its self-reported version number, the phpMyAdmin
application hosted on the remote web server is 4.4.x prior to
4.4.15.3 or 4.5.x prior to 4.5.4. It is, therefore, affected by the
following vulnerabilities :

  - An information disclosure vulnerability exists in the
    AES.php and Rijndael.php scripts that allows a remote
    attacker, via a specially crafted request, to disclose
    the software's installation path. (CVE-2016-2042)

  - A cross-site scripting vulnerability exists due to
    improper validation of user-supplied input to the
    normalization script when handling a crafted table name
    before returning it to users. An authenticated, remote
    attacker can exploit this, via specially crafted
    request, to execute arbitrary script code in a user's
    browser session. (CVE-2016-2043)

Note that Nessus has not attempted to exploit these issues but has
instead relied only on the application's self-reported version number.");
