WordPress < 4.6 Multiple Vulnerabilities
high Nessus Plugin ID 93111
Language:
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 4.6. It is, therefore, affected by multiple vulnerabilities :- A path traversal vulnerability exists in the WordPress Admin API in the wp_ajax_update_plugin() function in ajax-actions.php due to improper sanitization of user-supplied input. An authenticated, remote attacker can exploit this, via a specially crafted request, to cause a denial of service condition. (CVE-2016-6896)
- A cross-site request forgery vulnerability (XSRF) exists in the admin-ajax.php script due to a failure to require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. An unauthenticated, remote attacker can exploit this, by convincing a user to follow a specially crafted link, to perform arbitrary AJAX updates. (CVE-2016-6897)
- An information disclosure vulnerability exists in the wp_ajax_update_plugin() function in the ajax-actions.php script due to performing a call to get_plug_data() before checking capabilities. An authenticated, remote attacker can exploit this to bypass intended read-access restrictions, resulting in a disclosure of sensitive information. (CVE-2016-10148)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
