It carries a CVSS score of 5.5 (reachable over the network). The issue is fixed in version 3.3.103; sites on affected versions should update now.

Vulnerability Overview

The Zephyr Project Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in all versions up to, and including, 3.3.102 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.

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

Reaching this weakness in Zephyr Project Manager <= 3.3.102 takes a caller who can reach the endpoint. 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 Zephyr Project Manager the fix is 3.3.103: builds <= 3.3.102 are affected, anything from 3.3.103 onward is not.

Remediation

Update to version 3.3.103, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Zephyr Project Manager: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Zephyr Project Manager 3.3.103 closes this, and updating the plugin is the step that ends it.
