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 is triggered by manipulation of the 'ID' parameter, which is not properly sanitized before being used in SQL queries. This allows a remote attacker to inject malicious SQL code without requiring authentication or user interaction, potentially leading to unauthorized access to the backend database. The vulnerability affects confidentiality by exposing sensitive student and school data, integrity by allowing unauthorized data modification or deletion, and availability by potentially enabling denial-of-service conditions through crafted queries. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of remote exploitation without privileges but limited scope and impact. No patches or fixes have been published yet, and while no active exploitation has been reported, the public availability of exploit code increases the risk of attacks. The vulnerability is particularly concerning for educational institutions relying on this software for managing courses and student information, as exploitation could compromise critical academic and personal data. The lack of authentication and user interaction requirements makes this vulnerability easier to exploit remotely, emphasizing the need for urgent remediation.

For European organizations, particularly educational institutions using itsourcecode School Management System 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive student records, including personal identification and academic data, violating data protection regulations such as GDPR. Integrity of academic records could be compromised, affecting trust and operational continuity. Availability impacts could disrupt school management operations, causing administrative delays. The public availability of exploit code increases the likelihood of opportunistic attacks, including data theft, ransomware deployment, or system sabotage. Institutions lacking robust network segmentation or intrusion detection may be more vulnerable. The reputational damage and potential regulatory penalties from data breaches could be severe. Additionally, attackers could leverage this vulnerability as a foothold for lateral movement within educational networks, escalating the threat landscape.

Specific mitigation steps include: 1) Immediate code review and remediation of the /course/index.php file to implement parameterized queries or prepared statements for all database interactions involving the 'ID' parameter, eliminating direct concatenation of user input into SQL commands. 2) Implement rigorous input validation and sanitization to reject malformed or unexpected input values. 3) Deploy Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns targeting the vulnerable endpoint. 4) Conduct thorough logging and monitoring of database queries and application logs to detect anomalous activities indicative of exploitation attempts. 5) Restrict network access to the application server, limiting exposure to trusted networks or VPNs where feasible. 6) Plan and test patches or updates from the vendor once available, prioritizing their deployment. 7) Educate IT and security staff about the vulnerability and signs of exploitation to enhance incident response readiness. 8) Regularly back up critical data and verify restoration procedures to mitigate impact of potential data corruption or deletion.
