CVE-2025-6954 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Employee Management System, specifically within the /applyleave.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring authentication or user interaction, by injecting crafted SQL statements through the vulnerable parameter. This can lead to unauthorized access to the backend database, potentially allowing attackers to read, modify, or delete sensitive employee data, escalate privileges, or even execute administrative commands depending on the database permissions. 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. However, the impact on confidentiality, integrity, and availability is rated as low individually, which moderates the overall severity. No official patches or mitigations have been published yet, and while no exploits are currently known to be in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is an employee management system likely used by organizations to manage leave and employee records. Given the critical nature of employee data and the potential for lateral movement within corporate networks, this vulnerability poses a significant risk if left unaddressed.

For European organizations using Campcodes Employee Management System 1.0, this vulnerability could lead to unauthorized disclosure or manipulation of employee data, including leave records and potentially sensitive personal information. This could result in violations of GDPR and other data protection regulations, leading to legal penalties and reputational damage. Additionally, attackers exploiting this vulnerability could gain a foothold within the corporate network, potentially escalating attacks to other systems. The remote and unauthenticated nature of the exploit increases the risk of widespread compromise, especially in organizations with internet-facing deployments of this system. Disruption of employee management processes could also impact operational efficiency. Given the criticality of employee data and the regulatory environment in Europe, the impact extends beyond technical compromise to legal and business continuity concerns.

1. Immediate mitigation should include restricting external access to the /applyleave.php endpoint through network segmentation or firewall rules to limit exposure. 2. Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the 'ID' parameter. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize all inputs, especially the 'ID' parameter. 4. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5. Engage with the vendor for official patches or updates; if unavailable, consider temporary workarounds such as disabling the affected functionality if feasible. 6. Educate IT and security teams about the vulnerability and ensure incident response plans are updated to handle potential exploitation. 7. Perform vulnerability scanning and penetration testing to identify any other potential injection points within the system. 8. For organizations with compliance requirements, document mitigation steps and risk acceptance decisions carefully.
