The CVE-2022-46794 vulnerability represents a critical cross-site request forgery flaw within the weightbasedshipping.Com WooCommerce Weight Based Shipping plugin, affecting versions up to and including 5.4.1. This vulnerability resides in the WordPress ecosystem and specifically targets e-commerce platforms utilizing WooCommerce for their online store operations. The flaw allows authenticated attackers with minimal privileges to execute unauthorized actions on behalf of legitimate users, potentially compromising the integrity of shipping configurations and customer data within affected online stores. The vulnerability stems from insufficient validation of request origins and lack of proper anti-CSRF token implementation in the plugin's administrative interfaces.
The technical implementation of this CSRF vulnerability occurs through the manipulation of HTTP requests that modify shipping configurations or weight-based shipping rules within the WooCommerce admin panel. Attackers can craft malicious requests that appear legitimate to the WordPress backend system, exploiting the absence of proper CSRF protection mechanisms. The vulnerability typically manifests when users visit compromised websites or click on malicious links while authenticated to their WooCommerce stores, enabling attackers to perform unauthorized modifications to shipping methods, weight calculations, or pricing structures. This flaw operates at the application layer and requires user interaction to be exploited effectively, making it particularly dangerous in environments where administrators frequently access their stores from potentially compromised networks.
The operational impact of this vulnerability extends beyond simple configuration changes, as it can lead to significant financial losses through manipulation of shipping costs, unauthorized access to administrative functions, or disruption of normal commerce operations. An attacker could potentially alter shipping weight calculations to increase costs for customers or modify shipping rules to bypass normal delivery procedures. The vulnerability affects businesses of all sizes that rely on the weightbasedshipping.Com plugin, with potential consequences including loss of customer trust, financial discrepancies in shipping charges, and possible regulatory compliance issues. The impact is particularly severe for e-commerce sites handling high volumes of transactions where shipping configurations directly affect revenue streams and customer satisfaction.
Mitigation strategies for CVE-2022-46794 require immediate action including upgrading to the patched version of the weightbasedshipping.Com WooCommerce Weight Based Shipping plugin, which addresses the CSRF vulnerability through proper implementation of anti-CSRF tokens and origin validation. System administrators should also implement additional security measures such as enforcing strict content security policies, monitoring for unusual administrative activities, and ensuring that all plugin updates are applied promptly. The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery flaws in web applications, and corresponds to ATT&CK technique T1548.002 for privilege escalation through web application vulnerabilities. Organizations should also consider implementing multi-factor authentication for administrative accounts and regular security audits of third-party plugins to prevent similar vulnerabilities from compromising their e-commerce infrastructure.
