multiple vulnerabilities.");

"According to its self-reported version number, the phpMyAdmin
application hosted on the remote web server is 4.0.x prior to
4.0.10.13, 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 :

  - A security bypass vulnerability exists due to the use of
    the Math.random() JavaScript function which does not
    provide cryptographically secure random numbers. A
    remote attacker can exploit this to guess passwords via
    a brute-force attack. (CVE-2016-1927)

  - An information disclosure vulnerability exists in
    multiple scripts that allows a remote attacker, via a
    specially crafted request, to disclose the software's
    installation path. (CVE-2016-2038)

  - A security bypass vulnerability exists due to generating
    XSRF tokens with cryptographically insecure values. A
    remote attacker can exploit this to bypass intended
    access restrictions by predicting a value.
    (CVE-2016-2039)

  - Multiple cross-site scripting vulnerabilities exist due
    to improper validation of user-supplied input to the
    home, database search, and zoom search pages. An
    authenticated, remote attacker can exploit this, via a
    specially crafted request, to execute arbitrary script
    code in a user's browser session. (CVE-2016-2040)

  - A security bypass vulnerability exists due to a failure
    to use a constant-time algorithm for comparing XSRF
    tokens. A remote attacker can exploit this, via a timing
    attack, to bypass intended access restrictions.
    (CVE-2016-2041)

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