At a glance

CVE-2024-9438 is a medium-severity Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in the SEUR Oficial WordPress plugin, affecting versions <= 2.2.11. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

The SEUR Oficial plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'change_service' parameter in all versions up to, and including, 2.2.11 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as <, >, and & that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.

Remediation

Update to version 2.2.12, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to SEUR Oficial: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: SEUR Oficial 2.2.12 closes this, and updating the plugin is the step that ends it.
