CVE-2025-7218 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Payroll Management System. The vulnerability arises from improper sanitization of the 'ID' parameter in the /ajax.php?action=delete_position endpoint. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially altering or extracting sensitive payroll data from the backend database. The vulnerability requires no authentication or user interaction, making it accessible to unauthenticated remote attackers. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is rated as low individually but combined could lead to significant data exposure or unauthorized data modification. Although no exploits are currently known in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The lack of available patches or mitigation from the vendor further elevates the threat. Payroll systems typically contain sensitive employee information and financial data, making this vulnerability particularly critical in environments where the Campcodes Payroll Management System is deployed. Attackers exploiting this vulnerability could exfiltrate payroll records, manipulate salary data, or disrupt payroll operations, leading to financial loss, reputational damage, and regulatory compliance issues.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive employee payroll data, including personal identification and salary information. This exposure risks violating the EU's General Data Protection Regulation (GDPR), potentially resulting in significant fines and legal consequences. Manipulation of payroll data could disrupt business operations, cause financial discrepancies, and erode employee trust. Given the critical nature of payroll systems in organizational workflows, successful exploitation could also lead to operational downtime and increased incident response costs. Additionally, the public disclosure of the vulnerability may prompt threat actors to develop and deploy automated attack tools targeting European companies using this system, increasing the likelihood of widespread exploitation.

European organizations using Campcodes Payroll Management System 1.0 should immediately audit their systems for the presence of the vulnerable version. In the absence of an official patch, organizations should implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the /ajax.php?action=delete_position endpoint, specifically filtering suspicious 'ID' parameter inputs. 2) Restrict network access to the payroll management system to trusted internal IP ranges and VPNs to reduce exposure to external attackers. 3) Conduct thorough input validation and sanitization at the application layer, if source code access is available, to neutralize malicious inputs. 4) Monitor logs for anomalous database queries or repeated access attempts to the vulnerable endpoint. 5) Prepare incident response plans focusing on data breach containment and notification in compliance with GDPR. 6) Engage with the vendor for updates or patches and plan for timely system upgrades once available. 7) Consider isolating the payroll system in a segmented network zone to limit lateral movement in case of compromise.
