At a glance
CVE-2023-27417 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Affiliate Super Assistent WordPress plugin, affecting versions <= 1.5.1. 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 1.5.2; sites on affected versions should update now. Disclosed March 2023, reported by Kévin Mosbahi (Mika).
Vulnerability Overview
The Affiliate Super Assistent plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.1. This is due to missing or incorrect nonce validation on several functions such as the '_displayPreDispatcher', '_displayDispatcher', & '_displayTestPage' functions. This makes it possible for unauthenticated attackers to perform many actions like updating plugin settings 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)
Affiliate Super Assistent <= 1.5.1 carries this weakness at _displayPreDispatcher, 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 Affiliate Super Assistent the fix is 1.5.2: builds <= 1.5.1 are affected, anything from 1.5.2 onward is not.
Remediation
Update to version 1.5.2, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Affiliate Super Assistent: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Affiliate Super Assistent 1.5.2 closes this, and updating the plugin is the step that ends it.
