CVE-2025-9743 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Human Resource Integrated System, specifically within an unknown function in the login_attendance2.php file. The vulnerability arises from improper sanitization or validation of the input parameters employee_id and date, which are susceptible to malicious manipulation. An attacker can remotely exploit this flaw without requiring authentication or user interaction, by crafting specially designed input values that alter the intended SQL queries executed by the application. This can lead to unauthorized access to the backend database, allowing the attacker to read, modify, or delete sensitive HR data, potentially including employee records, attendance logs, and other confidential information. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with a vector string showing that the attack is network exploitable (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and has partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no public exploit is currently known to be actively used in the wild, the exploit code has been released publicly, increasing the risk of exploitation. The absence of patches or mitigation links at this time means organizations using this software version remain vulnerable until a fix is provided or applied.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive human resource data. Compromise of employee information can lead to privacy violations under GDPR regulations, resulting in legal penalties and reputational damage. Unauthorized data modification or deletion could disrupt HR operations, affecting payroll, attendance tracking, and compliance reporting. Since the vulnerability can be exploited remotely without authentication, attackers could leverage it to gain persistent access or pivot to other internal systems, increasing the overall security risk. Organizations relying on the affected Human Resource Integrated System version 1.0 may face operational disruptions and data breaches, which could have cascading effects on workforce management and regulatory compliance within the European context.

Immediate mitigation steps include implementing strict input validation and parameterized queries or prepared statements in the affected login_attendance2.php file to prevent SQL injection. Until an official patch is released, organizations should consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious SQL injection payloads targeting employee_id and date parameters. Network segmentation should be enforced to limit access to the HR system from untrusted networks. Regular monitoring of logs for anomalous database query patterns or repeated failed login attempts can help detect exploitation attempts early. Additionally, organizations should prioritize upgrading to a patched version once available and conduct thorough security assessments of all web-facing HR applications. Employee training on recognizing phishing or social engineering attempts that might accompany exploitation attempts is also recommended.
