WordPress < 4.3.1 Multiple Vulnerabilities

medium Nessus Plugin ID 85985

Synopsis

The PHP application running on the remote web server is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to WordPress 4.3.1 or later.
