CVE-2024-6666 is a critical SQL Injection vulnerability identified in the WP ERP plugin for WordPress, which provides comprehensive HR, recruitment, job listings, WooCommerce CRM, and accounting solutions. The flaw exists in all versions up to and including 1.13.0 and is caused by insufficient escaping and lack of proper parameterized queries for the 'vendor_id' parameter. This vulnerability allows authenticated attackers with the 'erp_ac_view_sales_summary' capability (Accounting Manager role or higher) to inject arbitrary SQL commands into existing queries. This improper neutralization of special elements in SQL commands (CWE-89) can be exploited to extract sensitive data, modify records, or disrupt database integrity and availability. The CVSS 3.1 base score of 8.8 reflects the vulnerability's network attack vector, low attack complexity, required privileges, and no user interaction, combined with high confidentiality, integrity, and availability impacts. Although no known exploits are currently in the wild, the vulnerability poses a significant risk due to the widespread use of WP ERP in business-critical WordPress environments. The vulnerability was publicly disclosed on July 11, 2024, and no official patches have been linked yet, emphasizing the need for immediate mitigation steps.

The exploitation of CVE-2024-6666 can lead to severe consequences for organizations using the WP ERP plugin. Attackers with limited privileges can escalate their access to sensitive financial, HR, and CRM data by extracting confidential information from the database. This can result in data breaches exposing employee records, payroll information, customer data, and business financials. Additionally, attackers could alter or delete critical data, causing operational disruptions and loss of data integrity. The availability of the ERP system could also be impacted if attackers execute destructive SQL commands. Given the plugin’s role in managing core business functions, such compromises could lead to regulatory non-compliance, reputational damage, financial losses, and operational downtime. Organizations with publicly accessible WordPress installations or weak internal access controls are particularly vulnerable. The lack of known exploits in the wild currently reduces immediate risk but does not diminish the urgency of remediation due to the vulnerability’s high severity and ease of exploitation.

1. Immediately restrict access to the 'erp_ac_view_sales_summary' capability and other high-privilege roles to trusted personnel only. 2. Implement strict input validation and sanitization on the 'vendor_id' parameter at the application level to prevent injection of malicious SQL code. 3. Apply the principle of least privilege by reviewing and minimizing user roles and capabilities within WP ERP. 4. Monitor database logs and application logs for unusual or suspicious SQL queries that may indicate attempted exploitation. 5. If possible, deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the vulnerable parameter. 6. Stay alert for official patches or updates from the WP ERP vendor and apply them promptly once available. 7. Consider isolating the WordPress environment or using database user accounts with limited permissions to reduce the blast radius of potential attacks. 8. Conduct regular security audits and penetration testing focusing on WordPress plugins and their database interactions. 9. Educate administrators and developers about secure coding practices and the risks of SQL injection vulnerabilities.
