At a glance

CVE-2019-13414 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Rencontre WordPress plugin, affecting versions < 3.1.3. It carries a CVSS score of 4.8 (reachable over the network; low attack complexity). The issue is fixed in version 3.1.3; sites on affected versions should update now. Disclosed July 2019, reported by Admavidhya N.

Vulnerability Overview

The Rencontre – Dating Site plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several parameters found in the inc/rencontre_widget.php file such as 'pays' in versions up to, and including, 3.1.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

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

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

Rencontre < 3.1.3 carries this weakness at pays, and reaching it 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 Rencontre the fix is 3.1.3: builds < 3.1.3 are affected, anything from 3.1.3 onward is not.

Remediation

Update to version 3.1.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Rencontre: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Rencontre 3.1.3 closes this, and updating the plugin is the step that ends it.
