CVE-2026-1176 is a SQL injection vulnerability identified in itsourcecode School Management System version 1.0, specifically within an unknown function in the /subject/index.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which can be manipulated remotely by an unauthenticated attacker to inject malicious SQL statements. This allows attackers to perform unauthorized database queries, potentially leading to data leakage, data modification, or deletion. The vulnerability does not require any user interaction or privileges, making it easily exploitable over the network. The CVSS 4.0 score is 6.9 (medium severity), reflecting the network attack vector, low complexity, no authentication, and partial impact on confidentiality, integrity, and availability. Although no patches or fixes have been officially released, the exploit code is publicly available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is used primarily in educational environments to manage school-related data. The lack of authentication and user interaction requirements combined with the public exploit availability makes this a significant risk for affected organizations.

For European organizations, particularly educational institutions using itsourcecode School Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive student and staff data, including personal information and academic records. Exploitation could lead to data breaches, loss of data integrity, and potential disruption of school operations. The compromise of such systems may also have regulatory implications under GDPR due to exposure of personal data. Additionally, attackers could leverage the vulnerability to escalate attacks within the network or pivot to other systems. The impact extends beyond confidentiality to include potential denial of service if data is corrupted or deleted. Given the critical nature of educational data and the reliance on these systems for daily operations, the threat could cause significant operational and reputational damage.

Immediate mitigation steps include implementing strict input validation and sanitization on the 'ID' parameter within /subject/index.php to prevent SQL injection. Developers should refactor the code to use parameterized queries or prepared statements to eliminate direct SQL command concatenation. Network-level protections such as web application firewalls (WAFs) can be configured to detect and block SQL injection attempts targeting this endpoint. Organizations should conduct thorough code audits of the entire application to identify and remediate similar vulnerabilities. Since no official patch is currently available, isolating the affected system from untrusted networks or restricting access to trusted users can reduce exposure. Regular monitoring of logs for suspicious database queries and unusual activity is recommended. Finally, organizations should plan to upgrade or replace the vulnerable software with a secure version once available.
