WordPress 4.7.x < 4.7.2 REST API 'id' Parameter Privilege Escalation

high Nessus Plugin ID 97210

Language:

Synopsis

The remote web server hosts a PHP script that is affected by a privilege escalation vulnerability.

Description

The WordPress application running on the remote web server is version 4.7.x prior to 4.7.2. It is, therefore, affected by a privilege escalation vulnerability in the REST API due to a failure to properly sanitize user-supplied input to the 'id' parameter when editing or deleting blog posts. An unauthenticated, remote attacker can exploit this issue to run arbitrary PHP code, inject content into blog posts, modify blog post attributes, or delete blog posts.

The WordPress REST API is enabled by default as of version 4.7.0. This vulnerability was silently patched in WordPress version 4.7.2.

Note that WordPress is reportedly affected by additional vulnerabilities; however, Nessus has not tested for these.

Solution

Upgrade to WordPress version 4.7.2 or later.
