At a glance

This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the WP Go Maps WordPress plugin, affecting versions < 7.11.28. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 7.11.28; sites on affected versions should update now. Disclosed June 2019.

Vulnerability Overview

The WP Google Maps plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 7.11.27. This is due to missing nonce validation on the wpgmza_settings_page_post() function. This makes it possible for authenticated attackers to modify the plugin's settings.

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 interaction from a victim user.

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

WP Go Maps < 7.11.28 carries this weakness at wpgmza_settings_page_post(), 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 WP Go Maps the fix is 7.11.28: builds < 7.11.28 are affected, anything from 7.11.28 onward is not.

Remediation

Update to version 7.11.28, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Go Maps: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Go Maps 7.11.28 closes this, and updating the plugin is the step that ends it.
