CVE-2025-6957 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Employee Management System, specifically within the /process/eprocess.php file. The vulnerability arises from improper sanitization of the 'mailuid' parameter, which an attacker can manipulate to inject malicious SQL code. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is exploitable over the network (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is low individually but combined can lead to significant data exposure or modification. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS 4.0 score is 6.9, indicating a medium severity level. The vulnerability can lead to unauthorized data access, data manipulation, or potentially full compromise of the underlying database, depending on the database permissions and system configuration. Given that the affected system is an employee management platform, sensitive employee data such as personal information, payroll, and access credentials could be at risk. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement compensating controls.

For European organizations using Campcodes Employee Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of employee data. Exploitation could lead to unauthorized disclosure of personal data, violating GDPR requirements and potentially resulting in regulatory fines and reputational damage. Additionally, attackers could manipulate employee records, affecting payroll, access rights, or operational workflows. The remote and unauthenticated nature of the exploit increases the attack surface, especially for organizations exposing the management system to internal networks or the internet. The medium CVSS score reflects moderate ease of exploitation with impactful consequences. Organizations in sectors with strict data protection mandates, such as finance, healthcare, and government, are particularly vulnerable. The absence of known exploits in the wild currently reduces immediate risk but the public disclosure means threat actors may develop exploits rapidly. The vulnerability could also serve as a pivot point for further network compromise if attackers leverage the system as a foothold.

1. Immediate mitigation should include restricting network access to the Campcodes Employee Management System, limiting it to trusted internal networks and VPNs only. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'mailuid' parameter. 3. Conduct thorough input validation and sanitization on all user-supplied inputs, especially the 'mailuid' parameter, using parameterized queries or prepared statements if source code access is available. 4. Monitor logs for unusual database queries or errors indicative of injection attempts. 5. Engage with the vendor to obtain patches or security updates; if none are available, consider upgrading to a newer, secure version or migrating to an alternative solution. 6. Perform regular security assessments and penetration testing focused on injection flaws. 7. Educate internal IT and security teams about this vulnerability and ensure incident response plans include scenarios involving SQL injection attacks. 8. Backup critical data regularly and ensure backups are secure and tested for restoration to mitigate potential data loss or corruption.
