At a glance

CVE-2024-7355 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Organization chart WordPress plugin, affecting versions <= 1.5.0. It carries a CVSS score of 4.9 (reachable over the network). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.5.1; sites on affected versions should update now. Disclosed August 2024, reported by Norbert Hofmann.

Vulnerability Overview

The Organization chart plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘title_input’ and 'node_description' parameter in all versions up to, and including, 1.5.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, this can only be exploited by administrators, but the ability to use and configure charts can be extended to subscribers.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Organization chart <= 1.5.0 carries this weakness at title_input, and reaching it takes an account at Subscriber level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Organization chart the fix is 1.5.1: builds <= 1.5.0 are affected, anything from 1.5.1 onward is not.

Remediation

Update to version 1.5.1, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Organization chart 1.5.1 closes this, and updating the plugin is the step that ends it.
