At a glance

CVE-2017-18513 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Responsive Menu WordPress plugin, affecting versions < 3.1.4. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.1.4; sites on affected versions should update now. Disclosed July 2020.

Vulnerability Overview

The responsive-menu plugin before 3.1.4 for WordPress has no CSRF protection mechanism for the admin interface.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Responsive Menu < 3.1.4 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Responsive Menu the fix is 3.1.4: builds < 3.1.4 are affected, anything from 3.1.4 onward is not.

Remediation

Update to version 3.1.4, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Responsive Menu: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Responsive Menu 3.1.4 closes this, and updating the plugin is the step that ends it.
