According to its version number, the WordPress application running on the remote web server is prior to 4.3.1. It is, therefore, potentially affected by multiple vulnerabilities :
A cross-site scripting vulnerability exists when processing shortcode tags due to improper validation of user-supplied input. An attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user’s browser session. (CVE-2015-5714)
An unspecified vulnerability exists that allows an authenticated attacker to publish private posts and make them ‘sticky’. (CVE-2015-5715)
An unspecified cross-site scripting vulnerability exists in the user list table. An attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user’s browser session.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
