Assigner: WPScan

Description

The Payment Plugins for PayPal WooCommerce WordPress plugin before 2.0.26 does not validate the order key before adding order data to the JavaScript configuration it outputs on the front end, allowing unauthenticated users to obtain the secret that gates access to any order and, through it, that customer's billing and shipping details, by iterating sequential order identifiers.

Attack-Flow Graph

Executive Summary

This vulnerability affects the Payment Plugins for PayPal WooCommerce WordPress plugin before version 2.0.26. It allows unauthenticated users to access sensitive customer data by exploiting a flaw in order key validation. The plugin outputs order data in JavaScript configuration without proper validation, enabling attackers to guess sequential order identifiers and retrieve the secret key needed to access any order's details.

Detection Guidance

Check if your WordPress site uses the Payment Plugins for PayPal WooCommerce plugin version prior to 2.0.26. Inspect the front-end JavaScript configuration for exposed order data or sequential order identifiers. Use WPScan to scan for vulnerable versions.

Impact Analysis

Unauthenticated attackers can obtain customer personally identifiable information (PII) such as billing and shipping details by exploiting sequential order identifiers. This could lead to identity theft, fraud, or unauthorized access to sensitive customer data.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized access to sensitive customer data. GDPR requires protection of personal data, while HIPAA mandates safeguards for protected health information. A breach could result in legal penalties and reputational damage.

Mitigation Strategies

Update the Payment Plugins for PayPal WooCommerce plugin to version 2.0.26 or later immediately. If updating is not possible, consider disabling the plugin temporarily until an update is applied.
