CVE-2025-13234 identifies a SQL injection vulnerability in itsourcecode Inventory Management System version 1.0. The vulnerability arises from improper sanitization of the PROID parameter in the /index.php?q=product endpoint, which allows attackers to inject malicious SQL code remotely without requiring authentication or user interaction. This injection flaw can be exploited to manipulate backend database queries, potentially enabling unauthorized data access, 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 low complexity, but requiring low privileges. The impact on confidentiality, integrity, and availability is limited but non-negligible, as attackers could extract sensitive inventory data or corrupt records. No official patches have been released yet, and while exploit code is publicly available, no confirmed active exploitation has been reported. The vulnerability highlights the critical need for secure coding practices such as input validation and use of parameterized queries in web applications handling inventory data.

For European organizations, this vulnerability poses risks primarily to the confidentiality and integrity of inventory data, which can disrupt supply chain operations, financial reporting, and asset management. Attackers exploiting this flaw could gain unauthorized access to sensitive business information, manipulate inventory records, or cause denial of service by corrupting database entries. Industries such as manufacturing, retail, logistics, and wholesale that rely on the itsourcecode Inventory Management System could face operational disruptions and reputational damage. The medium severity score reflects a moderate but tangible threat, especially if combined with other vulnerabilities or insider threats. Given the remote exploitability without authentication, attackers can launch attacks from outside the network, increasing exposure. European organizations with limited cybersecurity maturity or lacking timely patch management are particularly vulnerable.

Organizations should immediately audit their use of the itsourcecode Inventory Management System version 1.0 and restrict external access to the /index.php?q=product endpoint via network controls such as firewalls or web application firewalls (WAFs). Implement strict input validation and sanitization on the PROID parameter to block malicious SQL payloads. Where possible, refactor the application code to use parameterized queries or prepared statements to eliminate injection risks. Monitor logs for suspicious query patterns or unexpected database errors indicative of exploitation attempts. Engage with the vendor for patches or updates and apply them promptly once available. Conduct penetration testing focused on SQL injection vectors to identify residual vulnerabilities. Additionally, implement database access controls and encryption to limit damage in case of compromise. Educate developers on secure coding practices to prevent similar vulnerabilities in future releases.
