WP Data Access WordPress Plugin- A Short Introduction

WP Data Access is a powerful WordPress plugin that allows users to create professional, responsive data tables quickly and easily. The plugin features an intuitive table builder that supports a variety of features and allows users to make layout and behavior changes to almost any element of a DataTable through an advanced options section.

One of the key features of WP Data Access is its support for data tables of any size. This is made possible by the plugin’s use of the famous DataTables plugin for jQuery, which provides powerful support for manipulating large datasets within a browser.

Understanding the Privilege Escalation Vulnerability in WP Data Access WordPress Plugin

This is a high-severity privilege escalation vulnerability that stems from its Role Management feature. When enabled, it grants an authenticated attacker the ability to escalate their privileges to an administrator level via a profile update. This can lead to severe consequences, including unauthorized access, data theft, and complete control over the affected website.

The Security Vulnerability in WP Data Access Plugin

The WP Data Access plugin provides a feature called role management, which allows site owners to create custom roles and assign multiple roles to different users. The issue arises due to insufficient authorization checks in the multiple_roles_update function, making it possible for authenticated attackers with minimal permissions, such as subscribers, to modify their user roles [1].

Attackers can take advantage of this security flaw by supplying the wpda_role[] parameter during a profile update, which requires the “Enable role management” setting to be enabled for the site. This vulnerability allows users with limited permissions to assign themselves any role, including administrative roles, without proper authorization.

Exploiting the WP Data Access Plugin’s Security Flaw

To exploit the vulnerability, an attacker needs to be an authenticated user with minimal permissions, such as a subscriber. When updating their profile, they can manipulate the wpda_role[] parameter to change their user role to an administrative role or any other role with higher privileges. This unauthorized role change can grant the attacker access to sensitive site features and data, posing a significant security risk to the website. Please visit the blog for more technical details.
