At a glance

CVE-2022-27231 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the WP Statistics WordPress plugin, affecting versions < 13.2.0. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 13.2.0; sites on affected versions should update now. Disclosed May 2022, reported by Shogo Kumamaru.

Vulnerability Overview

Cross-site scripting vulnerability exists in WP Statistics versions prior to 13.2.0 because it improperly processes a platform parameter. By exploiting this vulnerability, an arbitrary script may be executed on the web browser of the user who is logging in to the website using the product.

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

Reaching this weakness in WP Statistics < 13.2.0 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 WP Statistics the fix is 13.2.0: builds < 13.2.0 are affected, anything from 13.2.0 onward is not.

Remediation

Update to version 13.2.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Statistics: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Statistics 13.2.0 closes this, and updating the plugin is the step that ends it.
