CVE-2025-6958 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Employee Management System, specifically affecting the /edit.php endpoint. The vulnerability arises due to improper sanitization or validation of the 'ID' parameter, which is directly used in SQL queries. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the backend database. Exploiting this vulnerability could enable attackers to read, modify, or delete sensitive employee data, escalate privileges, or even execute administrative commands on the database server. The vulnerability does not require any authentication or user interaction, making it highly accessible to attackers. Although the CVSS 4.0 score is 6.9 (medium severity), the potential impact on confidentiality, integrity, and availability of critical HR data is significant. No patches or fixes have been publicly disclosed yet, and no known exploits are reported in the wild, but the public disclosure increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the product, which may be in use in some organizations still running legacy systems. Given the nature of employee management systems, the exposure of personal and organizational data could have serious compliance and operational consequences.

For European organizations using Campcodes Employee Management System 1.0, this vulnerability poses a substantial risk to the confidentiality and integrity of employee data, including personal identification information, payroll details, and performance records. Exploitation could lead to data breaches violating GDPR regulations, resulting in legal penalties and reputational damage. Additionally, attackers could manipulate employee records or disrupt HR operations, impacting business continuity. The remote and unauthenticated nature of the attack vector increases the likelihood of exploitation, especially in organizations with externally accessible management portals. The lack of available patches means organizations must rely on mitigation strategies to reduce exposure. Given the criticality of employee data in Europe and strict data protection laws, this vulnerability could have severe financial and operational impacts if exploited.

Organizations should immediately audit their use of Campcodes Employee Management System to identify any deployments of version 1.0. If found, they should isolate or restrict access to the /edit.php endpoint, especially from external networks, using network segmentation and firewall rules. Implementing Web Application Firewalls (WAF) with custom rules to detect and block SQL injection patterns targeting the 'ID' parameter can provide temporary protection. Input validation and parameterized queries should be enforced if organizations have the capability to modify the application code. Monitoring logs for unusual database query patterns or repeated access attempts to /edit.php can help detect exploitation attempts early. Organizations should engage with the vendor for patches or updates and plan for an upgrade to a secure version once available. Additionally, conducting regular security assessments and penetration tests focusing on web application inputs will help identify similar vulnerabilities proactively.
