CVE-2026-3752 is a SQL injection vulnerability identified in SourceCodester Employee Task Management System version 1.0, specifically in the /daily-task-report.php script. The vulnerability arises from improper sanitization of the 'Date' GET parameter, which is directly used in SQL queries without adequate validation or parameterization. This flaw allows an attacker to craft malicious input that alters the intended SQL command, potentially enabling unauthorized data retrieval, modification, or deletion within the backend database. The attack vector is remote and does not require user interaction; however, the CVSS vector indicates that some level of privileges (PR:H) is necessary, suggesting that the attacker must be authenticated with higher privileges to exploit the vulnerability. The impact on confidentiality, integrity, and availability is limited but present, as indicated by the low to medium impact metrics in the CVSS vector. No official patches or fixes have been linked yet, and while no active exploitation in the wild has been reported, proof-of-concept exploits are publicly available, increasing the risk of future attacks. The vulnerability affects only version 1.0 of the product, which may limit its scope but still poses a risk to organizations relying on this system for employee task management and reporting.

The SQL injection vulnerability can allow attackers with authenticated access to manipulate database queries, potentially leading to unauthorized disclosure of sensitive employee or task data, unauthorized modification or deletion of records, and disruption of application functionality. This can compromise the confidentiality and integrity of organizational data and may impact availability if critical data is corrupted or deleted. Organizations using this system may face operational disruptions, data breaches, and compliance violations. The requirement for authenticated access reduces the risk from external unauthenticated attackers but does not eliminate insider threats or risks from compromised credentials. The availability of exploit code increases the likelihood of exploitation attempts, especially in environments with weak access controls or monitoring.

Organizations should immediately review and restrict access to the Employee Task Management System, ensuring that only trusted, authenticated users have high-level privileges. Implement input validation and parameterized queries or prepared statements in the /daily-task-report.php script to prevent SQL injection. If source code modification is possible, sanitize and validate the 'Date' parameter rigorously. Monitor logs for unusual database query patterns or failed injection attempts. Employ web application firewalls (WAFs) with rules targeting SQL injection patterns as a temporary mitigation. Conduct regular security assessments and penetration testing on the application. If available, apply vendor patches promptly once released. Additionally, enforce strong authentication mechanisms and consider multi-factor authentication to reduce the risk of credential compromise. Backup critical data regularly to enable recovery in case of data tampering or loss.
