According to its self-reported version number, the WordPress application running on the remote web server is prior to 4.7.1.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in the     PHPMailer component in the class.phpmailer.php script     due to improper handling of sender email addresses. An     unauthenticated, remote attacker can exploit this to     pass extra arguments to the sendmail binary, potentially     allowing the attacker to execute arbitrary code.
    (CVE-2016-10033, CVE-2016-10045)

  - An information disclosure vulnerability exists in the     REST API implementation due to a failure to properly     restrict listings of post authors. An unauthenticated,     remote attacker can exploit this, via a     wp-json/wp/v2/users request, to disclose sensitive     information. (CVE-2017-5487)

  - Multiple cross-site scripting (XSS) vulnerabilities     exist in the update-core.php script due to improper     validation of input to the plugin name or version     header. An unauthenticated, remote attacker can exploit     these, via a specially crafted request, to execute     arbitrary script code in a user's browser session.
    (CVE-2017-5488)

  - A cross-site request forgery (XSRF) vulnerability exists     due to improper handling of uploaded Flash files. An     unauthenticated, remote attacker can exploit this, via a     specially crafted Flash file, to hijack the     authentication of users. (CVE-2017-5489)

  - A cross-site scripting (XSS) vulnerability exists in the     class-wp-theme.php script due to improper validation of     input when handling theme name fallback. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary script     code in a user's browser session. (CVE-2017-5490)

  - A security bypass vulnerability exists in the     wp-mail.php script due to improper validation of mail     server names. An unauthenticated, remote attacker can     exploit this, via a spoofed mail server with the     'mail.example.com' name, to bypass intended security     restrictions. (CVE-2017-5491)

  - A cross-site request forgery (XSRF) vulnerability exists     in the widget-editing accessibility-mode feature due to     a failure to require multiple steps, explicit     confirmation, or a unique token when performing certain     sensitive actions for HTTP requests. An unauthenticated,     remote attacker can exploit this, by convincing a user     to follow a specially crafted URL, to hijack the     authentication of users or cause them to edit widgets.
    (CVE-2017-5492)

  - A security bypass vulnerability exists in the     ms-functions.php script due to the use of weak     cryptographic security for multisite activation keys. An     unauthenticated, remote attacker can exploit this, via a     specially crafted site sign-up or user sign-up, to     bypass intended access restrictions. (CVE-2017-5493)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
