WordPress < 4.5.3 Multiple Vulnerabilities

high Nessus Plugin ID 91810

Synopsis

A 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 4.5.3.
It is, therefore, affected by the following vulnerabilities :

- An unspecified flaw exists in the Customizer component that allows an unauthenticated, remote attacker to perform a redirect bypass.

- Multiple cross-site scripting vulnerabilities exist due to improper validation of user-supplied input when handling attachment names. An unauthenticated, remote attacker can exploit these issues, via a specially crafted request, to execute arbitrary script code in a user's browser session.

- An information disclosure vulnerability exists that allows an unauthenticated, remote attacker to disclose revision history.

- An unspecified flaw exists in oEmbed that allows an unauthenticated, remote attacker to cause a denial of service condition.

- An unspecified flaw exists that allows an unauthenticated, remote attacker to remove categories from posts.

- An unspecified flaw exists that is triggered when handling stolen cookies. An unauthenticated, remote attacker can exploit this to change user passwords.

- Multiple unspecified flaws exist in the sanitize_file_name() function that allow an unauthenticated, remote attacker to have an unspecified impact.

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 4.5.3 or later.
