CVE-2023-2447
At a glance
CVE-2023-2447 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the UserPro - Community and User Profile WordPress Plugin WordPress plugin, affecting versions <= 5.1.1. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.1.2; sites on affected versions should update now. Disclosed November 2023, reported by István Márton.
Vulnerability Overview
The UserPro plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.1.1. This is due to missing or incorrect nonce validation on the 'export_users' function. This makes it possible for unauthenticated attackers to export the users to a csv file, 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)
UserPro - Community and User Profile WordPress Plugin <= 5.1.1 carries this weakness at export_users, 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 UserPro - Community and User Profile WordPress Plugin the fix is 5.1.2: builds <= 5.1.1 are affected, anything from 5.1.2 onward is not.
Remediation
Update to version 5.1.2, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to UserPro - Community and User Profile WordPress Plugin: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: UserPro - Community and User Profile WordPress Plugin 5.1.2 closes this, and updating the plugin is the step that ends it.
