CVE-2025-6820 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Inventory Management System, specifically within the /php_action/createProduct.php file. The vulnerability arises from improper sanitization or validation of the 'productName' parameter, which can be manipulated by an attacker to inject malicious SQL code. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database without requiring any user interaction or privileges. The injection can lead to unauthorized data access, data modification, or even complete compromise of the database server. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been reported in the wild yet. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with the attack vector being network-based, no authentication or user interaction required, and low complexity. The impact on confidentiality, integrity, and availability is low to limited but still significant given the potential for data leakage or corruption. The vulnerability affects only version 1.0 of the product, and no official patches or mitigations have been published at this time.

For European organizations using the code-projects Inventory Management System 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of their inventory data. Successful exploitation could lead to unauthorized disclosure of sensitive business information, manipulation of inventory records, or disruption of inventory management operations. This could result in financial losses, operational downtime, and reputational damage. Given that the attack can be launched remotely without authentication or user interaction, attackers could automate exploitation attempts, increasing the risk of widespread compromise. Organizations in sectors with critical supply chains or regulatory compliance requirements (e.g., manufacturing, retail, logistics) may face additional legal and operational consequences if inventory data is compromised or manipulated.

Organizations should immediately assess their exposure to the affected Inventory Management System version 1.0. Since no official patches are currently available, practical mitigations include: 1) Implementing Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'productName' parameter in /php_action/createProduct.php. 2) Applying input validation and sanitization at the application or proxy level to reject or neutralize malicious input. 3) Restricting network access to the Inventory Management System to trusted internal IPs or VPNs to reduce exposure to remote attacks. 4) Monitoring application logs for unusual SQL errors or suspicious activity related to product creation. 5) Planning for an upgrade or replacement of the vulnerable system version as soon as a patch or secure version is released. 6) Conducting regular security assessments and penetration testing focused on injection vulnerabilities.
