CVE-2026-3752 is a SQL injection vulnerability identified in the SourceCodester Employee Task Management System version 1.0. The vulnerability arises from improper sanitization or validation of the 'Date' GET parameter in the /daily-task-report.php script. This flaw allows an unauthenticated remote attacker to inject arbitrary SQL commands by manipulating the Date parameter, potentially enabling unauthorized data access or modification. The vulnerability does not require user interaction and can be exploited over the network, increasing its attack surface. The CVSS 4.0 vector indicates no privileges required (PR:H suggests high privileges, but the vector states PR:H, which conflicts with the description; assuming the description is correct, no authentication is needed), low complexity, no user interaction, and partial impact on confidentiality, integrity, and availability. While no patches or fixes have been released, public exploit code is available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is a web-based employee task management system commonly used for tracking and reporting employee tasks. The lack of proper input validation in the GET parameter handler is a common security oversight leading to SQL injection, which can be leveraged to extract sensitive data, modify database contents, or disrupt application functionality.

The SQL injection vulnerability in the Employee Task Management System can have significant impacts on organizations using this software. Attackers exploiting this flaw can gain unauthorized access to sensitive employee data, task reports, and potentially other internal information stored in the backend database. This compromises confidentiality and may lead to data breaches. Integrity of the data can be undermined by unauthorized modifications, leading to inaccurate reporting or manipulation of employee task records. Availability may also be affected if attackers execute destructive SQL commands or cause database errors, disrupting normal operations. Given that the exploit can be initiated remotely without authentication, the attack surface is broad, increasing the likelihood of exploitation. Organizations relying on this system for operational management could face operational disruptions, reputational damage, and regulatory compliance issues if sensitive data is exposed or altered.

To mitigate this vulnerability, organizations should immediately implement input validation and parameterized queries or prepared statements in the /daily-task-report.php script to sanitize the 'Date' GET parameter and prevent SQL injection. If source code modification is not feasible, deploying a web application firewall (WAF) with rules to detect and block SQL injection attempts targeting this parameter can provide interim protection. Monitoring web server logs for suspicious query patterns involving the Date parameter can help detect exploitation attempts early. Organizations should also review and restrict database user permissions to minimize the impact of a potential injection attack. It is critical to apply any vendor patches once available. Additionally, conducting a thorough security audit of the entire application for similar injection flaws is recommended. Regular backups of the database should be maintained to enable recovery in case of data corruption or loss.
