Hello everyone! Today, we'll be discussing a new vulnerability that has been recently discovered and assigned CVE identifier CVE-2022-44628. This vulnerability is an Authenticated (admin+) Stored Cross-Site Scripting (XSS) in the JumpDEMAND Inc. 4ECPS Web Forms plugin (version <= .2.17) on WordPress. We will cover all the essential details, including the exploit and how it can affect your WordPress website. We'll also provide code snippets and links to the original references for a better understanding of the issue.
I. Vulnerability Overview
CVE-2022-44628 is a Stored XSS vulnerability in the 4ECPS Web Forms plugin for WordPress. This issue can be exploited by an attacker to execute arbitrary JavaScript code within the administrator's browser context, leading to a complete takeover of the affected site.
Stored XSS vulnerabilities occur when untrusted user input is stored by a web application (in this case, the 4ECPS Web Forms plugin on WordPress) and later displayed without proper sanitization and escaping, allowing an attacker to inject malicious JavaScript code into the vulnerable application.
II. Vulnerable Plugin Details
Plugin Name: 4ECPS Web Forms
Plugin Author: JumpDEMAND Inc.
Plugin Version: <= .2.17 (vulnerable)
URL: https://wordpress.org/plugins/4ecps-web-forms/
Description: The 4ECPS Web Forms plugin is designed to help Eye Care Professionals (ECPs) manage their web forms, including appointment booking, contact forms, and prescription refills.
III. Exploit Details
To exploit the vulnerability, an attacker with administrative or other high-level privileges on the target WordPress site must submit malicious JavaScript code through a vulnerable field in the plugin's settings page. The code will then be stored and executed whenever an administrator visits the affected page.
*Code Snippet:*
<script>alert("XSS payload");</script>
This simple payload will trigger a JavaScript alert with the message "XSS payload" when the stored XSS payload is executed in the administrator's browser. In a real attack, however, the payload could be much more complex and harmful.
