CVE-2025-6502 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Inventory Management System, specifically within the /php_action/changePassword.php file. The vulnerability arises from improper sanitization or validation of the user_id parameter, which is directly used in SQL queries without adequate protection. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the backend database. Exploitation does not require any authentication or user interaction, making it highly accessible to attackers. The vulnerability can lead to unauthorized data access, modification, or deletion, compromising the confidentiality, integrity, and availability of the inventory management system's data. Although the CVSS 4.0 score is 6.9 (medium severity), the lack of authentication and remote exploitability elevate the risk. The vulnerability affects only version 1.0 of the product, and no official patches or fixes have been published yet. No known exploits are currently observed in the wild, but public disclosure increases the likelihood of exploitation attempts. The Inventory Management System is typically used by organizations to manage stock, orders, and related business processes, making the data stored critical for operational continuity and business intelligence.

For European organizations using code-projects Inventory Management System 1.0, this vulnerability poses a significant risk to business operations and data security. Successful exploitation could lead to unauthorized access to sensitive inventory data, including stock levels, supplier information, and potentially customer data if integrated. This could disrupt supply chain management, cause financial losses, and damage organizational reputation. Additionally, attackers could manipulate or delete critical data, leading to operational downtime or erroneous business decisions. Given the remote and unauthenticated nature of the attack, organizations with internet-facing deployments are particularly vulnerable. The medium CVSS score may underestimate the real-world impact since the vulnerability affects core business data and can be exploited without barriers. Furthermore, compliance with European data protection regulations such as GDPR could be jeopardized if personal or sensitive data is exposed or altered, leading to legal and financial penalties.

1. Immediate mitigation should include restricting access to the /php_action/changePassword.php endpoint by implementing network-level controls such as IP whitelisting or VPN access to limit exposure. 2. Employ Web Application Firewalls (WAFs) configured with custom rules to detect and block SQL injection patterns targeting the user_id parameter. 3. Conduct a thorough code review and implement parameterized queries or prepared statements to sanitize all inputs, especially user_id, to prevent SQL injection. 4. If possible, upgrade to a newer, patched version of the Inventory Management System once available or apply vendor-provided patches promptly. 5. Monitor logs for suspicious activity related to changePassword.php and unusual database queries to detect exploitation attempts early. 6. Consider isolating the Inventory Management System from direct internet exposure by placing it behind secure application gateways or reverse proxies. 7. Educate development and IT teams on secure coding practices and the importance of input validation to prevent similar vulnerabilities. 8. Perform regular vulnerability scanning and penetration testing focused on injection flaws to proactively identify and remediate issues.
