CVE-2025-47648: Axima Payment Gateway CSRF Vulnerability

CVE-2025-47648 Overview

CVE-2025-47648 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Pays – WooCommerce Payment Gateway WordPress plugin (axima-payment-gateway). This vulnerability allows attackers to leverage CSRF to inject and store malicious scripts (Stored XSS), creating a chained attack that can compromise WordPress administrators and site visitors.

Critical Impact

Attackers can exploit the CSRF vulnerability to inject persistent malicious JavaScript into the WordPress site, potentially leading to session hijacking, credential theft, administrative account compromise, and malware distribution to site visitors.

Affected Products

• Pays – WooCommerce Payment Gateway (axima-payment-gateway) versions up to and including 2.6
• WordPress installations running vulnerable versions of the plugin
• WooCommerce stores utilizing the Pays payment gateway integration

Technical Details for CVE-2025-47648

Vulnerability Analysis

This vulnerability combines two distinct attack vectors into a chained exploit. The primary vulnerability is a Cross-Site Request Forgery (CSRF) weakness (CWE-352) in the Pays – WooCommerce Payment Gateway plugin. The absence of proper CSRF token validation on sensitive plugin endpoints allows attackers to craft malicious requests that, when executed by an authenticated administrator, inject stored XSS payloads into the WordPress database.

The stored XSS component means that any injected malicious script persists in the application and executes whenever the affected page or data is rendered. This persistence significantly amplifies the impact compared to reflected XSS attacks, as multiple users can be affected over time without requiring individual social engineering for each victim.

Root Cause

The root cause of this vulnerability lies in the failure to implement proper CSRF protection mechanisms on plugin forms and AJAX handlers. WordPress provides built-in nonce verification functions (wp_nonce_field(), wp_verify_nonce(), check_admin_referer()) specifically designed to prevent CSRF attacks. The vulnerable plugin versions fail to properly implement these security controls, allowing state-changing requests to be submitted without proper origin verification.

Additionally, the plugin fails to adequately sanitize and escape user-supplied input before storing it in the database, enabling the Stored XSS component of the attack chain.

Attack Vector

The attack typically follows this sequence:

1. The attacker identifies plugin endpoints that lack CSRF protection and accept user input
2. A malicious HTML page is crafted containing a hidden form that targets the vulnerable endpoint with XSS payload data
3. The attacker social engineers a logged-in WordPress administrator to visit the malicious page
4. The administrator's browser automatically submits the forged request with their valid session cookies
5. The plugin processes the request and stores the malicious JavaScript payload
6. The stored XSS payload executes whenever users access the affected page, potentially stealing credentials, session tokens, or performing actions on behalf of victims

The attack requires minimal user interaction – simply viewing a malicious page while logged into the WordPress admin panel is sufficient to trigger the CSRF and plant the stored XSS payload.

Detection Methods for CVE-2025-47648

Indicators of Compromise

• Unexpected JavaScript code in plugin settings or database fields related to payment gateway configuration
• Suspicious outbound connections from visitor browsers to unknown external domains
• Administrator session anomalies or unauthorized configuration changes
• Unusual database modifications to wp_options entries related to axima-payment-gateway

Detection Strategies

• Review WordPress database tables for unexpected script tags or JavaScript code in payment gateway settings
• Monitor web server logs for suspicious POST requests to plugin admin endpoints from external referrers
• Implement Content Security Policy (CSP) headers to detect and block inline script execution attempts
• Deploy web application firewall (WAF) rules to detect CSRF attack patterns and XSS payloads

Monitoring Recommendations

• Enable WordPress audit logging to track all plugin configuration changes with user attribution
• Configure browser-side monitoring for unexpected script injections and suspicious DOM modifications
• Set up alerts for database modifications to payment gateway configuration tables
• Monitor for unusual admin session activity following external website visits

How to Mitigate CVE-2025-47648

Immediate Actions Required

• Update the Pays – WooCommerce Payment Gateway plugin to a patched version if available
• Review and audit all plugin settings for unexpected JavaScript or HTML code injections
• Implement additional CSRF protection at the server level using security plugins
• Consider temporarily deactivating the vulnerable plugin until a patch is released

Patch Information

Refer to the Patchstack Vulnerability Advisory for the latest patch information and update guidance. Website administrators should check for plugin updates through the WordPress dashboard or contact the plugin vendor directly for remediation timelines.

Workarounds

• Install a WordPress security plugin that adds additional CSRF protection layers to admin forms
• Implement strict Content Security Policy headers to mitigate stored XSS payload execution
• Restrict WordPress admin panel access to trusted IP addresses only
• Enable two-factor authentication for all administrator accounts to reduce session hijacking impact
• Regularly backup the database and monitor for unauthorized modifications to plugin settings

# Add Content Security Policy header to mitigate XSS (Apache .htaccess)
<IfModule mod_headers.c>
    Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; frame-ancestors 'self';"
</IfModule>

# For Nginx configuration
# add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; frame-ancestors 'self';" always;
