CVE-2025-4815 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/supplier_update.php file. The vulnerability arises from improper sanitization or validation of the 'Name' 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 user interaction or privileges. The injection can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the system's data. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been reported in the wild at this time. The CVSS 4.0 base score is 6.9, reflecting a medium severity level due to the remote, unauthenticated nature of the attack vector combined with limited impact on confidentiality, integrity, and availability. The vulnerability does not require user interaction or privileges, and the attack surface is network accessible, making it a significant risk for organizations using this software version.

For European organizations utilizing the Campcodes Sales and Inventory System version 1.0, this vulnerability poses a tangible risk to business operations and data security. Exploitation could lead to unauthorized access to sensitive supplier and inventory data, potentially resulting in data breaches, financial loss, and disruption of supply chain management. The integrity of inventory records could be compromised, leading to inaccurate stock levels and erroneous business decisions. Additionally, attackers could leverage the vulnerability to escalate attacks within the network or pivot to other systems. Given the critical role of sales and inventory systems in retail, manufacturing, and distribution sectors, exploitation could disrupt operational continuity and damage organizational reputation. Compliance with European data protection regulations such as GDPR could also be jeopardized if personal or sensitive data is exposed or manipulated.

To mitigate this vulnerability, organizations should immediately audit their use of Campcodes Sales and Inventory System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement input validation and parameterized queries or prepared statements in the supplier_update.php functionality to prevent SQL injection. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the vulnerable parameter. Conduct thorough code reviews and penetration testing focused on input handling in the affected module. Restrict network access to the application to trusted internal networks or VPNs to reduce exposure. Monitor application logs for suspicious query patterns indicative of injection attempts. Additionally, ensure regular backups of critical data to enable recovery in case of data corruption or deletion.
