CVE-2026-1545 identifies a SQL injection vulnerability in itsourcecode School Management System version 1.0, located in the /course/index.php file. The vulnerability stems from insufficient input validation of the 'ID' parameter, which is directly used in SQL queries without proper sanitization or parameterization. This flaw allows remote attackers to inject malicious SQL code by manipulating the 'ID' argument, potentially leading to unauthorized data retrieval, modification, or deletion within the backend database. The attack vector requires no authentication or user interaction, increasing the risk of automated exploitation. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, and no privileges required. Although no known exploits are currently active in the wild, proof-of-concept exploits have been publicly disclosed, increasing the likelihood of future attacks. The vulnerability impacts confidentiality, integrity, and availability of the system's data, including sensitive educational records. No official patches or updates have been linked yet, so mitigation relies on implementing secure coding practices such as prepared statements and input validation. Organizations using this software should monitor for updates and apply fixes promptly to prevent exploitation.

The SQL injection vulnerability in itsourcecode School Management System 1.0 can have significant impacts on organizations, particularly educational institutions that rely on this software for managing sensitive student and course data. Successful exploitation can lead to unauthorized disclosure of confidential information, including personal identifiable information (PII) of students and staff. Attackers could also modify or delete critical data, disrupting school operations and undermining data integrity. In severe cases, attackers might escalate the attack to compromise the underlying database server or pivot to other internal systems, affecting availability and broader network security. The remote and unauthenticated nature of the exploit increases the risk of widespread automated attacks. Organizations failing to address this vulnerability may face reputational damage, regulatory penalties related to data protection laws, and operational downtime.

To mitigate CVE-2026-1545, organizations should immediately implement input validation and sanitization for the 'ID' parameter in the /course/index.php file. Specifically, developers should refactor the code to use parameterized queries or prepared statements to prevent SQL injection. If source code access is limited, deploying a Web Application Firewall (WAF) with custom rules to detect and block SQL injection attempts targeting the vulnerable parameter can provide interim protection. Regularly monitoring logs for suspicious query patterns related to the 'ID' parameter is recommended. Organizations should also track vendor communications for official patches or updates and apply them promptly once available. Conducting security code reviews and penetration testing focused on injection flaws in the application will help identify and remediate similar vulnerabilities. Finally, educating developers on secure coding practices and enforcing least privilege principles on database accounts can reduce the attack surface.
