CVE-2025-9740 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Human Resource Integrated System, specifically affecting the /log_query.php file. The vulnerability arises due to improper sanitization or validation of the 'ID' parameter, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or deletion. Given the CVSS 4.0 vector AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P, the attack can be executed remotely with low attack complexity, no privileges, and no user interaction, affecting confidentiality, integrity, and availability to a limited extent. The exploit has been publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The vulnerability's medium severity rating reflects the moderate impact and ease of exploitation, but the scope is limited to the affected version 1.0 of this specific HR system.

For European organizations using the code-projects Human Resource Integrated System 1.0, this vulnerability poses a significant risk to sensitive employee and organizational data. Successful exploitation could lead to unauthorized disclosure of personal and HR-related information, manipulation of records, or disruption of HR services. This could result in regulatory non-compliance, especially under GDPR, leading to legal penalties and reputational damage. The ability to exploit the vulnerability remotely without authentication increases the threat surface, making it easier for attackers to target organizations. Additionally, the integrity and availability of HR data could be compromised, impacting business operations and employee trust. Organizations relying heavily on this system for critical HR functions are particularly vulnerable to operational disruptions and data breaches.

Organizations should immediately assess their deployment of the code-projects Human Resource Integrated System version 1.0 and prioritize upgrading to a patched or newer version once available. In the absence of an official patch, implement strict input validation and parameterized queries or prepared statements in the /log_query.php script to sanitize the 'ID' parameter and prevent SQL injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. Conduct thorough code reviews and penetration testing focused on input handling in the HR system. Additionally, monitor logs for suspicious activities related to the 'ID' parameter and restrict external access to the HR system where possible, limiting exposure to trusted networks or VPNs. Regularly back up HR data securely to enable recovery in case of data tampering or loss.
