At a glance

CVE-2022-3776 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Restaurant Menu WordPress plugin, affecting versions <= 2.3.1. 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 2.3.2; sites on affected versions should update now. Disclosed October 2022, reported by ptsfence.

Vulnerability Overview

The Restaurant Menu – Food Ordering System – Table Reservation plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.3.1. This is due to missing or incorrect nonce validation on several functions called via AJAX actions such as forms_action, set_option, & chosen_options to name a few . This makes it possible for unauthenticated attackers to perform a variety of administrative actions like modifying forms, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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 Restaurant Menu <= 2.3.1 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 Restaurant Menu the fix is 2.3.2: builds <= 2.3.1 are affected, anything from 2.3.2 onward is not.

Remediation

Update to version 2.3.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Restaurant Menu: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Restaurant Menu 2.3.2 closes this, and updating the plugin is the step that ends it.
