At a glance

CVE-2024-7492 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the MainWP Child Reports WordPress plugin, affecting versions <= 2.2. 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 2.2.1; sites on affected versions should update now. Disclosed August 2024, reported by vgo0.

Vulnerability Overview

The MainWP Child Reports plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.2. This is due to missing or incorrect nonce validation on the network_options_action() function. This makes it possible for unauthenticated attackers to update arbitrary options that can be leveraged for privilege escalation via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This is only exploitable on multisite instances.

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)

MainWP Child Reports <= 2.2 carries this weakness at network_options_action(), 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 MainWP Child Reports the fix is 2.2.1: builds <= 2.2 are affected, anything from 2.2.1 onward is not.

Remediation

Update to version 2.2.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to MainWP Child Reports: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: MainWP Child Reports 2.2.1 closes this, and updating the plugin is the step that ends it.
