At a glance
CVE-2023-0554 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Quick Restaurant Menu WordPress plugin, affecting versions <= 2.0.2. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.1.0; sites on affected versions should update now. Disclosed January 2023, reported by Marco Wotschka.
Vulnerability Overview
The Quick Restaurant Menu plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.0.2. This is due to missing or incorrect nonce validation on its AJAX actions. This makes it possible for unauthenticated attackers to update menu items, via 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 integrity, availability.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Quick Restaurant Menu <= 2.0.2 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 Quick Restaurant Menu the fix is 2.1.0: builds <= 2.0.2 are affected, anything from 2.1.0 onward is not.
Remediation
Update to version 2.1.0, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Quick Restaurant Menu: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Quick Restaurant Menu 2.1.0 closes this, and updating the plugin is the step that ends it.
