In today's increasingly digital world, online commerce platforms are becoming more and more important. These platforms often rely on third-party plugins to add new functionality, like integration with popular social media platforms. One such plugin, the SAHU TikTok Pixel for E-Commerce, has recently been found to have a Stored Cross-Site Scripting (XSS) vulnerability affecting versions <= 1.2.2. The CVE-2023-46642 vulnerability was identified by researchers, and this post will dive into the details of the exploit, how it works, and how you can protect your website from it.

Exploit Details

The CVE-2023-46642 vulnerability revolves around an authentication bypass, specifically targeting the "admin+" privileged user group. This Stored Cross-Site Scripting (XSS) vulnerability allows an attacker to inject malicious code into the plugin's settings page, compromising its security and potentially affecting users of the corresponding E-Commerce platform.

To exploit this vulnerability, an attacker needs to send a specially crafted request to the vulnerable plugin using a specific parameter. When processed by the plugin, this request bypasses the authentication mechanism and, as part of the payload, delivers the malicious code. Once executed, this code may enable the attacker to manipulate data, steal sensitive information, or even gain complete control over the affected website.

Below is an example of the code used to exploit the CVE-2023-46642 vulnerability

POST /wp-admin/admin-ajax.php HTTP/1.1
Content-Type: application/x-www-form-urlencoded


In this code snippet, the action=stt4to_settings is used alongside the malicious payload in the stt4to_input_Test parameter. The POST request bypasses the authentication mechanism, and upon processing, the malicious script (<script>alert('XSS')</script>) is executed.
