CVE-2025-9742 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Human Resource Integrated System, specifically affecting the /login.php file. The vulnerability arises from improper handling of user-supplied input parameters 'user' and 'pass' during authentication processing. An attacker can remotely exploit this flaw by injecting malicious SQL code into these parameters, potentially manipulating the backend database queries. This could allow unauthorized access to sensitive information, bypass authentication controls, or modify database contents. The vulnerability requires no authentication or user interaction, and the attack vector is network-based, making it remotely exploitable. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation and the limited but significant impact on confidentiality, integrity, and availability. Although no public exploits are currently known in the wild, the existence of publicly available exploit code increases the risk of exploitation. The vulnerability does not require special privileges or user interaction, and the scope is limited to the affected system. No patches or mitigations have been officially released at the time of publication.

For European organizations using the code-projects Human Resource Integrated System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of employee data and other sensitive HR information. Successful exploitation could lead to unauthorized access to personal data, including identification, payroll, and employment records, potentially violating GDPR and other data protection regulations. The integrity of HR data could be compromised, leading to fraudulent modifications or disruptions in HR operations. Availability impact is possible if attackers manipulate database queries to cause denial of service or system crashes. Given the critical nature of HR systems in organizational operations, exploitation could disrupt business continuity and damage organizational reputation. The medium severity score suggests that while the vulnerability is serious, it may not lead to full system compromise without additional factors. However, the remote and unauthenticated nature of the exploit increases the urgency for mitigation.

Organizations should immediately audit their use 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 web application firewall (WAF) rules to detect and block SQL injection patterns targeting /login.php parameters 'user' and 'pass'. Employ input validation and parameterized queries or prepared statements within the application code to sanitize user inputs. Conduct thorough code reviews focusing on authentication modules to identify and remediate injection points. Monitor logs for unusual login attempts or SQL errors indicative of exploitation attempts. Restrict database user permissions associated with the HR system to the minimum necessary to limit the impact of a successful injection. Additionally, implement network segmentation to isolate the HR system from broader enterprise networks, reducing lateral movement risk. Finally, ensure regular backups of HR data are maintained and tested for integrity to support recovery in case of data tampering or loss.
