"According to its self-reported version number, the Sophos Web
Appliance software running on the remote host is prior to 4.3.1. It
is, therefore, affected by multiple vulnerabilities :

  - A remote command injection vulnerability exists in the
    web administration interface in the
    /controllers/MgrReport.php script when blocking and
    unblocking IP addresses due to improper validation of
    user-supplied input passed to the unblockip' and
    'blockip' parameters. An authenticated, remote attacker
    can exploit this, via a specially crafted request, to
    inject arbitrary shell commands. (CVE-2016-9553)

  - A remote command injection vulnerability exists in the
    web administrative interface in the
    /controllers/MgrDiagnosticTools.php script when
    performing diagnostic tests due to improper validation
    of user-supplied input passed to the url' parameter. An
    authenticated, remote attacker can exploit this, via a
    specially crafted request, to execute arbitrary script
    code in a user's browser session. (CVE-2016-9554)");
