At a glance

CVE-2022-44737 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the All-In-One Security (AIOS) WordPress plugin, affecting versions <= 5.1.0. 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 5.1.1; sites on affected versions should update now. Disclosed November 2022, reported by Rafie Muhammad.

Vulnerability Overview

The All In One WP Security & Firewall plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.1.0. This is due to incorrect nonce validation on the functions 'render_login_whitelist', 'render_rename_login', 'render_honeypot' functions and possible others. This makes it possible for unauthenticated attackers to perform bulk actions on the plugin's list tables (such as deleting blocked IP entries) via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. These actions would be restricted by manipulating entries by database ID, not by other fields (such as IP address).

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)

All-In-One Security (AIOS) <= 5.1.0 carries this weakness at render_login_whitelist, 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 All-In-One Security (AIOS) the fix is 5.1.1: builds <= 5.1.0 are affected, anything from 5.1.1 onward is not.

Remediation

Update to version 5.1.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to All-In-One Security (AIOS): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All-In-One Security (AIOS) 5.1.1 closes this, and updating the plugin is the step that ends it.
