Executive Summary

The Employee Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the 'form_title' parameter in the search_employee_directory shortcode in all versions up to and including 1.2.1.

This vulnerability occurs because the plugin does not properly sanitize or escape input provided to the 'form_title' parameter, allowing authenticated users with Contributor-level access or higher to inject arbitrary web scripts.

These injected scripts are stored and executed whenever any user accesses the page containing the injected content, potentially compromising user sessions or site integrity.

Impact Analysis

This vulnerability can allow an attacker with Contributor-level access or higher to inject malicious scripts into pages viewed by other users.

When other users visit the affected pages, the malicious scripts execute in their browsers, which can lead to theft of user credentials, session hijacking, defacement, or other malicious actions.

Because the vulnerability is stored XSS, the malicious code persists on the site until it is removed or the plugin is updated.

Detection Guidance

The vulnerability involves Stored Cross-Site Scripting (XSS) via the 'form_title' parameter in the search_employee_directory shortcode of the Employee Directory WordPress plugin. Detection would involve identifying if your WordPress site uses this plugin version 1.2.1 or earlier and if the shortcode is used with untrusted input in the 'form_title' parameter.

Since the vulnerability requires authenticated users with Contributor-level access or higher to inject scripts, detection can include reviewing pages where the shortcode is used and checking for suspicious script injections in the form title.

There are no specific commands provided in the resources to detect this vulnerability on your network or system.
