CVE-2024-0470 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Human Resource Integrated System, specifically within the /admin_route/inc_service_credits.php file. The vulnerability arises from improper sanitization or validation of the 'id' parameter, which allows an attacker to manipulate SQL queries executed by the application. This flaw enables remote attackers to inject malicious SQL code without requiring user interaction, potentially compromising the confidentiality, integrity, and availability of the underlying database. Although the exact database backend is not specified, exploitation could lead to unauthorized data disclosure, modification, or deletion, and in some cases, may allow privilege escalation or remote code execution depending on the database and application context. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The CVSS 3.1 base score is 6.3 (medium severity), reflecting network attack vector, low attack complexity, required privileges (PR:L), no user interaction, and impacts on confidentiality, integrity, and availability at a low level. The vulnerability is critical in nature due to the potential consequences of SQL injection but is rated medium because it requires some privileges and does not have known active exploitation currently. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement compensating controls.

For European organizations using the affected Human Resource Integrated System version 1.0, this vulnerability poses significant risks. Human Resource systems typically store sensitive personal data, including employee identities, payroll information, and possibly health or legal data protected under GDPR. Exploitation could lead to unauthorized access or exfiltration of personal data, resulting in privacy breaches, regulatory fines, and reputational damage. Integrity compromise could allow attackers to alter payroll or personnel records, causing operational disruption or fraud. Availability impacts could disrupt HR operations, affecting payroll processing and employee management. Given the remote attack vector and lack of user interaction, attackers could exploit this vulnerability stealthily. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, are particularly at risk. The public disclosure increases the likelihood of exploitation attempts, especially in environments where patching or mitigation is delayed.

Since no official patch is currently available, European organizations should prioritize the following mitigations: 1) Implement strict input validation and parameterized queries or prepared statements in the affected application code to prevent SQL injection. If source code modification is possible, refactor the 'id' parameter handling accordingly. 2) Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the vulnerable endpoint (/admin_route/inc_service_credits.php). 3) Restrict access to the administrative interface by IP whitelisting or VPN-only access to reduce exposure. 4) Monitor application logs and database logs for suspicious queries or unusual activity related to the 'id' parameter. 5) Conduct thorough security assessments and penetration tests focusing on injection flaws in the HR system. 6) Plan and prioritize upgrading or replacing the vulnerable system with a patched or more secure version as soon as it becomes available. 7) Educate system administrators and developers about secure coding practices to prevent similar vulnerabilities in the future.
