CVE-2025-13259 identifies a SQL injection vulnerability in Campcodes Supplier Management System version 1.0, located in the /manufacturer/edit_unit.php script. The vulnerability arises from improper sanitization of the 'ID' parameter, which an attacker can manipulate to inject arbitrary SQL commands. This flaw allows remote attackers to execute unauthorized SQL queries without requiring authentication or user interaction, increasing the risk of data leakage, unauthorized data modification, or even full database compromise depending on the backend database privileges. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L - low privileges), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability is rated medium severity with a CVSS score of 5.3. While no public exploit code is currently confirmed in the wild, the existence of a published exploit increases the risk of future attacks. The affected product is used for supplier management, which typically contains sensitive business and supplier data, making the vulnerability significant for organizations relying on this system for supply chain operations. The lack of available patches at the time of publication necessitates immediate mitigation efforts to reduce exposure.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive supplier and manufacturing data, potentially exposing confidential business information and intellectual property. Data integrity could be compromised by unauthorized modification or deletion of records, disrupting supply chain operations and causing financial and reputational damage. Availability impacts could arise if attackers execute destructive SQL commands or cause database corruption, leading to downtime of critical supplier management functions. Given the interconnected nature of European manufacturing and supply chains, a successful attack could have cascading effects on production and logistics. Organizations in sectors with stringent data protection regulations, such as GDPR, may face legal and compliance repercussions if data breaches occur. The medium severity rating suggests a moderate but tangible risk that should be addressed promptly to avoid escalation.

1. Monitor Campcodes vendor communications closely for official patches or updates addressing CVE-2025-13259 and apply them immediately upon release. 2. Implement strict input validation and sanitization on all parameters, especially the 'ID' parameter in /manufacturer/edit_unit.php, to prevent injection of malicious SQL code. 3. Deploy Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns targeting the affected endpoint. 4. Conduct regular code reviews and security testing (e.g., dynamic application security testing) on the supplier management system to identify and remediate injection flaws. 5. Restrict database user privileges for the application to the minimum necessary, limiting the potential damage from successful injection attacks. 6. Monitor logs for unusual database queries or errors that may indicate attempted exploitation. 7. Educate IT and security teams about this vulnerability to ensure rapid detection and response. 8. Consider network segmentation to isolate the supplier management system from critical infrastructure to limit lateral movement in case of compromise.
