At a glance

CVE-2022-3898 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the WP Affiliate Platform WordPress plugin, affecting versions <= 6.3.9. 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 6.4.0; sites on affected versions should update now. Disclosed November 2022, reported by Marco Wotschka.

Vulnerability Overview

The WP Affiliate Platform plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 6.3.9. This is due to missing or incorrect nonce validation on various functions including the affiliates_menu method. This makes it possible for unauthenticated attackers to delete affiliate records, via 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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in WP Affiliate Platform <= 6.3.9 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 WP Affiliate Platform the fix is 6.4.0: builds <= 6.3.9 are affected, anything from 6.4.0 onward is not.

Remediation

Update to version 6.4.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Affiliate Platform: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Affiliate Platform 6.4.0 closes this, and updating the plugin is the step that ends it.
