CVE-2026-0544 identifies a SQL Injection vulnerability in itsourcecode School Management System version 1.0, specifically in the /student/index.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which is directly used in SQL queries. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially extracting, modifying, or deleting sensitive data from the backend database. The CVSS 4.0 score of 6.9 (medium severity) reflects the network attack vector, no required privileges or user interaction, and partial impact on confidentiality, integrity, and availability. The vulnerability does not require authentication, making it accessible to any remote attacker. Although no official patches or vendor advisories are currently published, a public exploit is available, increasing the likelihood of exploitation. The vulnerability affects only version 1.0 of the product, which is typically deployed in educational environments to manage student data, grades, and administrative information. The lack of secure coding practices such as parameterized queries or prepared statements is the root cause. Attackers exploiting this vulnerability could gain unauthorized access to sensitive student records, alter grades, or disrupt system availability, leading to reputational damage and regulatory compliance issues.

For European organizations, particularly educational institutions using itsourcecode School Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of student and administrative data. Exploitation could result in unauthorized disclosure of personal data protected under GDPR, leading to legal and financial penalties. Integrity compromise could allow attackers to alter academic records or administrative information, undermining trust and operational reliability. Availability impacts, while partial, could disrupt school management operations, affecting educational delivery. The public availability of an exploit increases the risk of opportunistic attacks, including data theft, ransomware deployment, or further lateral movement within networks. Given the critical nature of educational data and the regulatory environment in Europe, the impact extends beyond technical damage to include compliance and reputational consequences. Organizations lacking timely mitigation may face increased exposure to targeted attacks or automated scanning by threat actors.

Immediate mitigation should focus on implementing robust input validation and sanitization for the 'ID' parameter in /student/index.php. Developers should refactor the code to use parameterized queries or prepared statements to prevent SQL injection. Until an official patch is released, organizations should deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable endpoint. Network-level protections such as IP reputation filtering and rate limiting can reduce exposure to automated attacks. Conduct thorough code reviews and security testing on all input handling modules within the application. Educate IT staff and administrators on monitoring logs for suspicious query patterns or unusual database activity. If feasible, isolate the affected system from critical networks and restrict access to trusted users only. Regular backups of the database should be maintained to enable recovery in case of data corruption or deletion. Engage with the vendor or community for updates and patches, and plan for an upgrade or replacement of the vulnerable software version.
