CVE-2026-3747 is a SQL injection vulnerability identified in the itsourcecode University Management System version 1.0, specifically within the /add_result.php script. The vulnerability stems from insufficient input validation or sanitization of the 'subject' parameter, which is used in SQL queries without proper escaping or parameterization. This flaw allows an unauthenticated remote attacker to inject arbitrary SQL commands by manipulating the 'subject' argument, potentially leading to unauthorized data access, modification, or deletion within the underlying database. The vulnerability does not require user interaction or privileges, and the attack vector is network accessible, making exploitation straightforward. The CVSS 4.0 base score is 6.9, reflecting medium severity due to partial impacts on confidentiality, integrity, and availability, and the lack of authentication or user interaction requirements. While no known exploits are currently active in the wild, a public exploit is available, increasing the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The affected system is typically deployed in educational institutions for managing academic results and related data, making the confidentiality and integrity of student records and grades a critical concern.

The exploitation of this SQL injection vulnerability can have significant consequences for organizations using the itsourcecode University Management System 1.0. Attackers could extract sensitive academic data such as student grades, personal information, and institutional records, leading to privacy violations and potential regulatory non-compliance. Data integrity could be compromised by unauthorized modification or deletion of records, undermining trust in academic results and institutional credibility. Availability of the system could also be affected if attackers execute destructive SQL commands or cause database corruption. The ease of remote exploitation without authentication increases the risk of widespread attacks, especially in environments where the system is exposed to the internet. Educational institutions worldwide could face reputational damage, legal liabilities, and operational disruptions if this vulnerability is exploited.

To mitigate CVE-2026-3747, organizations should immediately implement strict input validation and sanitization on the 'subject' parameter and any other user-supplied inputs in the /add_result.php script. Employing parameterized queries or prepared statements is critical to prevent SQL injection attacks. Until an official patch is released by itsourcecode, administrators should consider restricting network access to the affected system, such as limiting exposure to trusted internal networks or using web application firewalls (WAFs) with SQL injection detection and blocking capabilities. Regularly monitoring logs for suspicious database queries or unusual activity can help detect exploitation attempts early. Additionally, organizations should plan to apply vendor patches promptly once available and conduct security assessments to identify and remediate similar vulnerabilities in other parts of the system. Educating developers on secure coding practices and conducting code reviews can prevent recurrence of such issues.
