At a glance

This record tracks a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Ship To eCourier WordPress plugin, affecting versions <= 1.0.1. 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 1.0.2; sites on affected versions should update now. Disclosed May 2021, reported by WPScanTeam.

Vulnerability Overview

The Ship To eCourier plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.1. This is due to missing or incorrect nonce validation on the ste-ecourier-settings function. This makes it possible for unauthenticated attackers to change 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. 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 Ship To eCourier <= 1.0.1 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 Ship To eCourier the fix is 1.0.2: builds <= 1.0.1 are affected, anything from 1.0.2 onward is not.

Remediation

Update to version 1.0.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Ship To eCourier: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Ship To eCourier 1.0.2 closes this, and updating the plugin is the step that ends it.
