Understanding CVE-2023-3671

This section delves into the details of CVE-2023-3671, covering aspects like the vulnerability description, impact, affected systems and versions, as well as mitigation and prevention steps.

What is CVE-2023-3671?

The CVE-2023-3671 vulnerability stems from the MultiParcels Shipping For WooCommerce WordPress plugin failing to adequately sanitize and escape various parameters before displaying them on a web page. This oversight opens the door to Reflected Cross-Site Scripting attacks, enabling malicious actors to execute scripts in the context of high privilege users.

The Impact of CVE-2023-3671

With this vulnerability, attackers can craft malicious URLs that, when clicked by privileged users, execute unauthorized scripts in their browsers. This can lead to various consequences, such as unauthorized access to sensitive information, manipulation of user data, or even complete system compromise.

Technical Details of CVE-2023-3671

This section provides a deeper dive into the technical specifics of CVE-2023-3671, including the vulnerability description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description
