CVE-2025-13257 identifies a SQL injection vulnerability in the itsourcecode Inventory Management System version 1.0, specifically in the /admin/user/index.php?view=edit endpoint. The vulnerability arises from improper sanitization of the 'ID' parameter, which is susceptible to malicious SQL payloads. This flaw allows an unauthenticated remote attacker to manipulate backend SQL queries, potentially extracting, modifying, or deleting sensitive data stored in the database. The vulnerability does not require user interaction or privileges, making it easier to exploit. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low complexity and no authentication required, but with limited impact on confidentiality, integrity, and availability (each rated low). No patches or official fixes have been published yet, and while no known exploits are reported in the wild, the public disclosure increases the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the product, which is typically used by small to medium enterprises for inventory management. The lack of secure coding practices in input handling is the root cause, and the vulnerability could be leveraged to gain unauthorized access to user data or disrupt inventory operations.

For European organizations, exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive inventory and user data, potentially exposing confidential business information or customer details. Data integrity could be compromised by unauthorized modification or deletion of records, impacting operational accuracy and decision-making. Availability of the inventory management system might be degraded if attackers execute destructive SQL commands or cause database errors. Organizations in sectors relying heavily on inventory accuracy, such as manufacturing, retail, and logistics, could face operational disruptions and financial losses. Additionally, regulatory compliance risks arise if personal or sensitive data is exposed, potentially triggering GDPR violations and associated penalties. The medium severity rating suggests a moderate but tangible risk, especially for entities that have not implemented compensating controls or network segmentation. The remote and unauthenticated nature of the exploit increases the threat surface, making exposed systems attractive targets for opportunistic attackers or automated scanning tools.

Since no official patch is currently available, European organizations should immediately implement the following mitigations: 1) Restrict access to the /admin/user/index.php endpoint via network controls such as firewalls or VPNs to limit exposure to trusted administrators only. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ID' parameter. 3) Conduct manual code review and apply input validation and sanitization on the 'ID' parameter, preferably using parameterized queries or prepared statements to prevent SQL injection. 4) Monitor logs for suspicious query patterns or repeated failed attempts to exploit the vulnerability. 5) Isolate the inventory management system from critical internal networks to reduce lateral movement risk. 6) Plan and prioritize upgrading to a patched version once available or consider alternative inventory management solutions with better security posture. 7) Educate administrators about the risks and signs of exploitation attempts. These targeted actions go beyond generic advice by focusing on immediate containment and code-level remediation specific to this vulnerability.
