CVE-2025-69337: Wolmart Core SQL Injection Vulnerability

CVE-2025-69337 Overview

CVE-2025-69337 is a critical Blind SQL Injection vulnerability affecting the Wolmart Core WordPress plugin (wolmart-core) developed by don-themes. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing unauthenticated attackers to execute malicious SQL queries against the underlying database.

This Blind SQL Injection vulnerability enables attackers to extract sensitive data from WordPress databases without requiring any authentication or user interaction. The attack can be conducted entirely over the network, making it particularly dangerous for internet-facing WordPress installations using this plugin.

Critical Impact

Unauthenticated attackers can exploit this Blind SQL Injection to extract sensitive database contents including user credentials, personal information, and other confidential data stored in the WordPress database.

Affected Products

• Wolmart Core plugin versions through 1.9.6
• WordPress installations using the affected wolmart-core plugin
• E-commerce sites built with the Wolmart theme ecosystem

Technical Details for CVE-2025-69337

Vulnerability Analysis

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The Wolmart Core plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating a classic SQL Injection attack surface.

As a Blind SQL Injection variant, attackers cannot directly see the results of their injected queries in the application response. Instead, they must infer information about the database structure and contents by observing differences in application behavior, response times, or error conditions. This technique, while slower than traditional SQL Injection, can still lead to complete database compromise.

The vulnerability requires no authentication (PR:N) and no user interaction (UI:N), meaning any remote attacker with network access can attempt exploitation. The scope is changed (S:C), indicating the vulnerability can affect resources beyond the vulnerable component itself.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and sanitization within the Wolmart Core plugin's codebase. User-controllable input is being directly concatenated or interpolated into SQL query strings without proper parameterization or escaping.

WordPress provides secure database interaction methods through the $wpdb class, including prepared statements via $wpdb->prepare(). The vulnerable code path in Wolmart Core appears to bypass these security mechanisms, directly incorporating user input into database queries.

Attack Vector

The attack is network-based and requires no special privileges or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting the vulnerable parameter or endpoint within the Wolmart Core plugin.

Typical Blind SQL Injection exploitation involves:

1. Boolean-based blind injection: Crafting payloads that cause different application behavior based on true/false conditions in the SQL query
2. Time-based blind injection: Using SQL commands like SLEEP() or BENCHMARK() to cause measurable delays that reveal information about the database
3. Error-based extraction: Leveraging database error messages to extract data when verbose error reporting is enabled

The vulnerability affects the plugin's data handling functionality, where user input flows into database queries without adequate sanitization. See the Patchstack SQL Injection Advisory for additional technical details.

Detection Methods for CVE-2025-69337

Indicators of Compromise

• Unusual database query patterns in MySQL/MariaDB slow query logs containing SQL injection syntax such as UNION SELECT, OR 1=1, or SLEEP()
• Web server access logs showing requests to Wolmart Core endpoints with suspicious URL-encoded characters or SQL keywords
• Unexpected database errors or timeouts that may indicate time-based SQL injection attempts
• Evidence of data exfiltration or unauthorized database access in application logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting WordPress plugins
• Enable and monitor WordPress debug logging to capture suspicious database query errors
• Implement database activity monitoring to detect unusual query patterns or unauthorized data access
• Use intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Monitor web server logs for requests containing SQL injection indicators such as single quotes, double dashes, and SQL keywords
• Set up alerts for database connection anomalies or query execution time spikes
• Review WordPress plugin activity logs for unusual behavior from the Wolmart Core plugin
• Implement real-time monitoring of database queries for injection attempt patterns

How to Mitigate CVE-2025-69337

Immediate Actions Required

• Update the Wolmart Core plugin to a patched version as soon as one becomes available from don-themes
• Temporarily deactivate the Wolmart Core plugin if it is not essential to site operation until a patch is released
• Deploy WAF rules to block SQL injection attempts targeting the affected endpoints
• Review database access logs for any evidence of exploitation attempts

Patch Information

At the time of CVE publication, the vulnerability affects Wolmart Core versions through 1.9.6. Site administrators should monitor the WordPress plugin repository and the vendor's official channels for security updates. The Patchstack SQL Injection Advisory may provide additional remediation guidance as it becomes available.

Workarounds

• Implement a Web Application Firewall (WAF) with SQL injection protection rules to filter malicious requests before they reach the application
• Restrict network access to the WordPress admin area and plugin endpoints using IP whitelisting where feasible
• Enable WordPress debug mode temporarily to identify and log any exploitation attempts, then disable in production
• Consider using a WordPress security plugin that provides virtual patching capabilities for known vulnerabilities

# Example WAF rule for ModSecurity to block common SQL injection patterns
# Add to your Apache or Nginx ModSecurity configuration
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,log,msg:'SQL Injection Attempt Blocked'"

# Restrict access to WordPress plugin directories (Apache example)
# Add to .htaccess in wp-content/plugins/wolmart-core/
<Files "*.php">
  Order Deny,Allow
  Deny from all
  Allow from 127.0.0.1
</Files>
