CVE-2025-30524: Product Catalog SQL Injection Vulnerability

CVE-2025-30524 Overview

CVE-2025-30524 is a critical SQL Injection vulnerability discovered in the origincode Product Catalog plugin for WordPress. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing unauthenticated attackers to inject malicious SQL queries through the vulnerable plugin interface. This flaw affects all versions of the Product Catalog plugin from the initial release through version 1.0.4.

Critical Impact

This SQL Injection vulnerability allows remote attackers to extract sensitive database information, potentially compromise user credentials, and gain unauthorized access to WordPress installations without authentication.

Affected Products

• origincode Product Catalog plugin versions n/a through 1.0.4
• WordPress installations using the vulnerable Product Catalog plugin
• Web servers hosting affected WordPress configurations

Technical Details for CVE-2025-30524

Vulnerability Analysis

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The Product Catalog plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries executed against the WordPress database. This allows attackers to manipulate database queries by injecting specially crafted SQL statements through vulnerable input parameters.

The attack can be executed remotely over the network without requiring any authentication or user interaction. The vulnerability has a changed scope, meaning successful exploitation can impact resources beyond the vulnerable component itself, potentially affecting the entire WordPress installation and its underlying database. The primary impact is on data confidentiality, with attackers able to extract sensitive information from the database, while also posing a limited risk to system availability.

Root Cause

The root cause of this vulnerability lies in the plugin's failure to implement proper input validation and parameterized queries when processing user input. The Product Catalog plugin directly incorporates user-controlled data into SQL statements without adequate sanitization, escaping, or the use of prepared statements. This violates secure coding practices for database interactions and creates a direct path for SQL Injection attacks.

Attack Vector

The vulnerability is exploitable remotely via network access. Attackers can craft malicious HTTP requests containing SQL Injection payloads targeting vulnerable parameters within the Product Catalog plugin. Since no authentication or privileges are required, any remote attacker with network access to the WordPress installation can attempt exploitation.

The attack flow typically involves:

1. Identifying WordPress installations using the vulnerable Product Catalog plugin
2. Locating input fields or parameters that interact with the database
3. Injecting SQL statements to manipulate query logic
4. Extracting sensitive data such as user credentials, post content, or configuration details

Detailed technical information about this vulnerability is available in the Patchstack vulnerability database.

Detection Methods for CVE-2025-30524

Indicators of Compromise

• Unusual database queries in MySQL/MariaDB logs containing SQL injection patterns such as UNION SELECT, OR 1=1, or comment sequences (--, /**/)
• Unexpected access patterns to the Product Catalog plugin endpoints
• Database error messages appearing in web server logs indicating malformed queries
• Evidence of data exfiltration attempts targeting WordPress user tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL Injection patterns in HTTP requests
• Monitor WordPress and web server access logs for suspicious requests targeting the Product Catalog plugin (displayproduct)
• Deploy database activity monitoring to identify anomalous query patterns
• Use security scanning tools to identify WordPress installations running vulnerable versions of the Product Catalog plugin

Monitoring Recommendations

• Enable detailed query logging on the WordPress database to capture potential injection attempts
• Configure alerts for database errors that may indicate attempted SQL Injection attacks
• Implement file integrity monitoring on WordPress core and plugin files
• Regularly audit WordPress plugin inventories to identify vulnerable or outdated components

How to Mitigate CVE-2025-30524

Immediate Actions Required

• Immediately deactivate and remove the Product Catalog plugin version 1.0.4 and earlier from all WordPress installations
• Audit database access logs for any evidence of prior exploitation
• Review WordPress user accounts for unauthorized additions or privilege changes
• Consider resetting database credentials as a precautionary measure

Patch Information

At the time of this publication, administrators should check the Patchstack advisory for updated patch information from the plugin developer. If no patch is available, removal of the vulnerable plugin is strongly recommended until a secure version is released.

Workarounds

• Disable or remove the Product Catalog plugin until a patched version is available
• Implement Web Application Firewall rules to filter SQL Injection payloads targeting WordPress endpoints
• Restrict database user privileges for the WordPress installation to limit potential damage from successful exploitation
• Consider using alternative product catalog plugins that are actively maintained with proper security practices
