At a glance

This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Advanced Menu Manager Pro WordPress plugin, affecting versions <= 3.0.6. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.0.7; sites on affected versions should update now. Disclosed November 2023.

Vulnerability Overview

The Advance Menu Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.0.6. This is due to missing or incorrect nonce validation on the dsamm_action_ajax_for_delete_menu(), dsamm_amm_duplicate_menu(), and dsamm_action_ajax_for_create_menu() functions. This makes it possible for unauthenticated attackers to duplicate, modify, and create menus 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.

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

Advanced Menu Manager Pro <= 3.0.6 carries this weakness at dsamm_action_ajax_for_delete_menu(), and reaching it 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 Advanced Menu Manager Pro the fix is 3.0.7: builds <= 3.0.6 are affected, anything from 3.0.7 onward is not.

Remediation

Update to version 3.0.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Advanced Menu Manager Pro: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Advanced Menu Manager Pro 3.0.7 closes this, and updating the plugin is the step that ends it.
