WordPress < 4.4.2 Multiple Vulnerabilities

high Nessus Plugin ID 88579

Synopsis

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

Description

According to its self-reported version number, the WordPress application running on the remote web server is prior to 4.4.2.
It is, therefore, affected by the following vulnerabilities :

- A cross-site redirection vulnerability exists due to a failure by the application to validate certain input.
An unauthenticated, remote attacker can exploit this, via a specially crafted link, to redirect a victim from a legitimate web site to an arbitrary web site of the attacker's choosing, thus allowing further attacks on client-side software, such as web browsers or document rendering software. (CVE-2016-2221)

- A server-side request forgery vulnerability exists in which the server can be induced into performing unintended actions when handling certain requests. An unauthenticated, remote attacker can exploit this, via crafted requests to certain local URIs, to conduct further host-based attacks, such as bypassing access restrictions, conducting port scanning, enumerating internal networks and hosts, or invoking additional protocols. (CVE-2016-2222)

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 version 4.4.2 or later.
