Attack-Flow Graph

Executive Summary

This vulnerability affects the GetPaid WordPress plugin before version 2.8.55. It allows unauthenticated attackers to forge payment notifications from Worldpay, tricking the system into marking invoices as paid without any actual payment being made.

Detection Guidance

To detect this vulnerability, check if your WordPress site uses the GetPaid plugin version before 2.8.55. Inspect the plugin files for missing authentication checks on Worldpay payment notifications. Look for forged payment confirmations in server logs or database entries marked as paid without valid transactions.

Impact Analysis

Attackers could exploit this to obtain products or services without paying by falsifying payment confirmations. This could lead to financial losses for merchants using the plugin.

Compliance Impact

This vulnerability could lead to unauthorized transactions being recorded as paid, potentially violating compliance requirements for data integrity and financial accuracy in standards like GDPR and HIPAA. Unverified payment notifications may result in incorrect financial records, which could affect audit trails and regulatory reporting.

Mitigation Strategies

Update the GetPaid WordPress plugin to version 2.8.55 or later to address the vulnerability. Disable the plugin temporarily if an update is not immediately available.
