CVE-2025-28942: Trust Payments Gateway SQLi Vulnerability

CVE-2025-28942 Overview

CVE-2025-28942 is a critical SQL Injection vulnerability affecting the Trust Payments Gateway for WooCommerce plugin. The vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89), allowing attackers to inject malicious SQL queries through the plugin. This issue affects Trust Payments Gateway for WooCommerce versions through 1.1.4.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive data from WordPress databases, potentially compromising customer payment information, credentials, and other confidential data stored in affected WooCommerce installations.

Affected Products

• Trust Payments Gateway for WooCommerce versions up to and including 1.1.4
• WordPress installations running the vulnerable plugin versions
• WooCommerce stores utilizing Trust Payments as a payment gateway

Technical Details for CVE-2025-28942

Vulnerability Analysis

This SQL Injection vulnerability exists within the Trust Payments Gateway for WooCommerce plugin, a payment processing integration for WordPress e-commerce sites. The flaw allows attackers to manipulate database queries by injecting malicious SQL code through improperly sanitized input fields.

The vulnerability can be exploited remotely without any authentication or user interaction, making it particularly dangerous for publicly accessible WordPress sites. Successful exploitation could allow attackers to read sensitive database contents including customer information, order details, and potentially stored credentials.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize and validate user-supplied input before incorporating it into SQL queries. The plugin does not adequately escape or parameterize data before constructing database queries, allowing specially crafted input to be interpreted as SQL commands rather than data.

This violates secure coding practices that mandate the use of prepared statements or parameterized queries when handling user input in database operations. Without proper input validation and output encoding, the application becomes susceptible to SQL injection attacks.

Attack Vector

The attack can be executed remotely over the network without requiring authentication. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable parameters within the plugin's functionality.

The vulnerability manifests in the plugin's database interaction layer where user input is directly concatenated into SQL queries. For detailed technical information about the exploitation mechanics, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-28942

Indicators of Compromise

• Unusual database queries in WordPress/MySQL logs containing SQL syntax anomalies
• Web server access logs showing requests with SQL keywords (UNION, SELECT, INSERT) in URL parameters or POST data
• Unexpected database read operations or data exfiltration patterns
• Error messages in application logs indicating SQL syntax errors from malformed injection attempts

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting WordPress plugins
• Enable and monitor WordPress debug logging for database query anomalies
• Implement database activity monitoring to detect unauthorized SELECT operations on sensitive tables
• Use intrusion detection systems with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor web server logs for requests containing SQL injection payloads targeting the Trust Payments plugin endpoints
• Set up alerts for unusual database query volumes or patterns indicating data exfiltration
• Review WordPress audit logs for unexpected plugin behavior or configuration changes
• Implement real-time monitoring of database connections and query execution patterns

How to Mitigate CVE-2025-28942

Immediate Actions Required

• Update Trust Payments Gateway for WooCommerce to the latest patched version immediately
• If an update is not available, consider temporarily disabling the plugin until a fix is released
• Review database access logs for signs of prior exploitation
• Implement WAF rules to block SQL injection attempts targeting the plugin

Patch Information

Organizations should check for updates to the Trust Payments Gateway for WooCommerce plugin through the WordPress plugin repository or contact the vendor directly. The vulnerability affects versions through 1.1.4, so any version newer than this should contain the security fix.

For the latest patch information and security advisory details, refer to the Patchstack Vulnerability Report.

Workarounds

• Deploy a Web Application Firewall with SQL injection protection rules as a temporary mitigation
• Restrict access to the WordPress admin panel and payment gateway endpoints using IP allowlisting
• Implement database user privilege restrictions to limit the impact of potential SQL injection attacks
• Consider using a virtual patching solution through security plugins like Wordfence or Sucuri until an official patch is available

# Example: Restrict database user privileges (temporary mitigation)
# Revoke unnecessary privileges from WordPress database user
REVOKE DROP, ALTER, CREATE ON wordpress_db.* FROM 'wp_user'@'localhost';
# Ensure the user only has required permissions
GRANT SELECT, INSERT, UPDATE, DELETE ON wordpress_db.* TO 'wp_user'@'localhost';
FLUSH PRIVILEGES;
