CVE-2025-13259 is a SQL injection vulnerability identified in Campcodes Supplier Management System version 1.0, affecting the /manufacturer/edit_unit.php script. The vulnerability arises from improper sanitization of the 'ID' parameter, which an attacker can manipulate remotely without authentication to inject malicious SQL commands. This flaw allows attackers to execute arbitrary SQL queries on the backend database, potentially leading to unauthorized data disclosure, data modification, or deletion. The vulnerability has a CVSS 4.0 base score of 5.3, indicating medium severity, with attack vector being network-based and no user interaction required. The attack complexity is low, but it requires low privileges, suggesting that an attacker with limited access could exploit it. The vulnerability impacts confidentiality, integrity, and availability, albeit with limited scope and impact compared to higher severity SQL injections. No patches or fixes have been officially published yet, and no known exploits are active in the wild, but the public disclosure increases the risk of exploitation attempts. The vulnerability is critical for organizations relying on Campcodes Supplier Management System for managing supplier data, as it could lead to leakage of sensitive supplier information or disruption of supply chain operations.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of supplier data managed through the Campcodes Supplier Management System. Exploitation could result in unauthorized access to sensitive supplier information, manipulation of supplier records, or disruption of supplier management workflows, potentially impacting procurement and supply chain operations. This could lead to financial losses, reputational damage, and regulatory compliance issues, especially under GDPR requirements for data protection. The availability of the system could also be affected if attackers execute destructive SQL commands, causing operational downtime. Given the interconnected nature of supply chains in Europe, a successful attack could have cascading effects on manufacturing and distribution processes. Organizations in sectors with critical supply chain dependencies, such as automotive, aerospace, and pharmaceuticals, are particularly vulnerable. The medium severity rating suggests that while the threat is serious, it may not lead to full system compromise without additional factors, but it still requires prompt attention to avoid escalation.

To mitigate this vulnerability, organizations should immediately conduct a thorough code review of the /manufacturer/edit_unit.php file to identify and remediate unsafe handling of the 'ID' parameter. Implement parameterized queries or prepared statements to prevent SQL injection. Input validation should be enforced to restrict the 'ID' parameter to expected data types and formats, such as numeric values only. Employ web application firewalls (WAF) with rules designed to detect and block SQL injection attempts targeting this endpoint. Monitor logs for suspicious activity related to the 'edit_unit.php' script and the 'ID' parameter. Since no official patch is available yet, consider isolating or restricting access to the affected system until a fix is released. Educate developers and administrators on secure coding practices and conduct regular security assessments of supplier management applications. Additionally, ensure that database accounts used by the application have the least privileges necessary to limit the impact of any successful injection.
