Vulnerability Overview

Cross-site request forgery (CSRF) vulnerability in the WordPress Simple Paypal Shopping Cart plugin before 3.6 for WordPress allows remote attackers to hijack the authentication of administrators for requests that change plugin settings.

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)

Reaching this weakness in Simple Shopping Cart < 3.6 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 Simple Shopping Cart the fix is 3.6: builds < 3.6 are affected, anything from 3.6 onward is not.

Remediation

Update to version 3.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Simple Shopping Cart: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Simple Shopping Cart 3.6 closes this, and updating the plugin is the step that ends it.
