At a glance

CVE-2023-0499 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the QuickSwish WordPress plugin, affecting versions <= 1.0.9. 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 1.1.0; sites on affected versions should update now. Disclosed February 2023, reported by István Márton.

Vulnerability Overview

The QuickSwish plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.9. This is due to missing or incorrect nonce validation on the 'plugin_activation' function. This makes it possible for unauthenticated attackers to activate arbitrary plugins already installed (but deactivated) on the site 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)

QuickSwish <= 1.0.9 carries this weakness at plugin_activation, 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 QuickSwish the fix is 1.1.0: builds <= 1.0.9 are affected, anything from 1.1.0 onward is not.

Remediation

Update to version 1.1.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to QuickSwish: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: QuickSwish 1.1.0 closes this, and updating the plugin is the step that ends it.
