At a glance

CVE-2022-25306 is a high-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the WP Statistics WordPress plugin, affecting versions <= 13.1.5. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 13.1.6; sites on affected versions should update now. Disclosed February 2022, reported by Muhammad Zeeshan (Xib3rR4dAr).

Vulnerability Overview

The WP Statistics WordPress plugin is vulnerable to Cross-Site Scripting due to insufficient escaping and sanitization of the browser parameter found in the ~/includes/class-wp-statistics-visitor.php file which allows attackers to inject arbitrary web scripts onto several pages that execute when site administrators view a sites statistics, in versions up to and including 13.1.5.

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, and no interaction from a victim user.

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

Reaching this weakness in WP Statistics <= 13.1.5 takes no account at all. 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 13.1.6: builds <= 13.1.5 are affected, anything from 13.1.6 onward is not.

Remediation

Update to version 13.1.6, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Statistics 13.1.6 closes this, and updating the plugin is the step that ends it.
