The vulnerability CVE-2026-3487 affects the itsourcecode College Management System version 1.0, specifically in the /admin/class-result.php script. The issue is an SQL Injection caused by improper sanitization of the course_code parameter, which is processed without adequate validation. This allows an attacker to craft malicious input that alters the intended SQL query logic, potentially enabling unauthorized data access, modification, or deletion within the backend database. The attack vector is remote and does not require user interaction, but it does require some level of privileges (PR:H) according to the CVSS vector, indicating that the attacker must have some authenticated access to exploit this vulnerability. The impact on confidentiality, integrity, and availability is low to limited, as indicated by the CVSS vector components VC:L, VI:L, and VA:L, meaning the attacker’s control over data and system disruption is partial. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no active exploitation has been reported so far. The lack of available patches or vendor advisories necessitates immediate attention from system administrators to implement compensating controls. The vulnerability highlights the importance of secure coding practices, especially input validation and parameterized queries, in web applications managing sensitive academic data.

This SQL Injection vulnerability can lead to unauthorized access to sensitive student and academic data, including grades, personal information, and course details. Attackers with some level of authenticated access could manipulate or extract data, potentially leading to data breaches, loss of data integrity, or disruption of academic operations. The availability of the system could also be affected if attackers execute destructive SQL commands. Educational institutions using this system may face reputational damage, regulatory penalties for data breaches, and operational downtime. Since the vulnerability requires some privilege level, insider threats or compromised accounts pose a significant risk. The public disclosure of the exploit increases the likelihood of attempted attacks, especially by opportunistic attackers targeting vulnerable educational software. The medium severity rating reflects a moderate risk but underscores the need for prompt remediation to prevent escalation or chaining with other vulnerabilities.

1. Immediately restrict access to the /admin/class-result.php page to trusted administrators only, using network-level controls such as IP whitelisting or VPN access. 2. Implement strict input validation and sanitization on the course_code parameter, preferably using parameterized queries or prepared statements to prevent SQL Injection. 3. Review and minimize database user privileges associated with the application to limit the impact of any successful injection. 4. Monitor database logs and application logs for unusual or suspicious queries that may indicate exploitation attempts. 5. Conduct a thorough code audit of the entire application to identify and remediate other potential injection points. 6. If possible, upgrade to a patched version once available or apply vendor-provided fixes promptly. 7. Educate administrators and developers on secure coding practices and the risks of SQL Injection. 8. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block SQL Injection attempts targeting this parameter. 9. Regularly back up the database and test restoration procedures to mitigate data loss risks. 10. Implement multi-factor authentication to reduce the risk of compromised credentials being used to exploit this vulnerability.
