CVE-2024-47634: CartBounty WooCommerce CSRF Vulnerability

CVE-2024-47634 Overview

CVE-2024-47634 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the CartBounty – Save and recover abandoned carts for WooCommerce plugin (also known as woo-save-abandoned-carts). This vulnerability allows attackers to perform unauthorized actions on behalf of authenticated users by tricking them into visiting a malicious website or clicking a crafted link while authenticated to their WordPress administration panel.

Critical Impact

This vulnerability enables attackers to perform state-changing actions without the user's consent, potentially compromising the integrity and confidentiality of WooCommerce store data including abandoned cart information and customer details.

Affected Products

• CartBounty – Save and recover abandoned carts for WooCommerce versions up to and including 8.2
• WordPress installations running the vulnerable woo-save-abandoned-carts plugin
• WooCommerce stores utilizing CartBounty for abandoned cart recovery

Technical Details for CVE-2024-47634

Vulnerability Analysis

This CSRF vulnerability exists in the CartBounty plugin due to missing or insufficient validation of nonce tokens on state-changing operations. When WordPress plugins fail to properly implement CSRF protections, they become susceptible to attacks where malicious actors can forge requests that execute administrative actions.

The vulnerability allows an unauthenticated attacker to craft a malicious request that, when triggered by an authenticated administrator, executes privileged operations within the plugin's context. This could include modifying plugin settings, accessing or manipulating abandoned cart data, or performing other administrative functions that should require explicit user intent.

CSRF attacks against WooCommerce plugins are particularly concerning because they can expose sensitive e-commerce data including customer information, cart contents, and potentially lead to broader site compromise.

Root Cause

The root cause of CVE-2024-47634 stems from CWE-352 (Cross-Site Request Forgery), which occurs when the application fails to verify that a request was intentionally submitted by the authenticated user. The CartBounty plugin lacks proper nonce verification on one or more administrative endpoints, allowing attackers to craft requests that bypass the same-origin policy through social engineering.

WordPress provides built-in nonce functions (wp_nonce_field(), wp_verify_nonce()) specifically designed to prevent CSRF attacks, but these protections must be consistently implemented across all state-changing operations.

Attack Vector

The attack requires an authenticated WordPress administrator to be tricked into visiting a malicious page or clicking a crafted link while logged into their WordPress site. The attacker constructs a request targeting vulnerable CartBounty endpoints and embeds it in a hidden form or image tag on an attacker-controlled website.

When the victim visits the malicious page, their browser automatically includes session cookies, causing the forged request to execute with the victim's privileges. This is a network-based attack that requires no authentication by the attacker themselves.

The vulnerability can be exploited via hidden forms auto-submitted through JavaScript, image tags with source URLs pointing to vulnerable endpoints, or links distributed through phishing campaigns targeting WooCommerce administrators.

Detection Methods for CVE-2024-47634

Indicators of Compromise

• Unexpected changes to CartBounty plugin configuration or settings without administrator action
• Suspicious administrative activity in WordPress audit logs during periods when administrators were not actively working
• Evidence of abandoned cart data manipulation or unauthorized exports
• Referer headers in access logs showing requests originating from external, untrusted domains

Detection Strategies

• Monitor WordPress admin activity logs for CartBounty-related actions that don't correlate with legitimate administrative sessions
• Implement Content Security Policy (CSP) headers to help detect and block unauthorized cross-origin requests
• Review web server access logs for POST requests to CartBounty endpoints with suspicious or missing referer headers
• Deploy web application firewall (WAF) rules to detect and block CSRF attack patterns

Monitoring Recommendations

• Enable comprehensive WordPress activity logging for all plugin administrative actions
• Configure alerts for bulk changes or exports of abandoned cart data
• Monitor for unusual patterns in CartBounty endpoint access from authenticated sessions
• Implement browser-based anomaly detection for unexpected administrative actions

How to Mitigate CVE-2024-47634

Immediate Actions Required

• Update CartBounty – Save and recover abandoned carts for WooCommerce to a version newer than 8.2 that addresses this vulnerability
• Verify the integrity of CartBounty plugin settings and review for unauthorized changes
• Audit recent administrative activity for signs of exploitation
• Temporarily disable the plugin if an update is not immediately available and abandoned cart functionality is not critical

Patch Information

The vendor has released a security update addressing this CSRF vulnerability. Administrators should update the CartBounty plugin through the WordPress admin dashboard or by downloading the latest version from the WordPress plugin repository. Detailed vulnerability information is available through the Patchstack Security Advisory.

Workarounds

• Implement additional authentication requirements for sensitive CartBounty operations through a security plugin
• Configure Content Security Policy headers to restrict form submissions and frame ancestors
• Use browser security extensions that warn administrators before submitting forms to external domains
• Limit administrative access to trusted IP addresses only through WordPress security plugins or web server configuration
