Attack Chain

1. Attacker identifies a vulnerable instance of ProjectsAndPrograms School Management System running a version up to commit 6b6fae5426044f89c08d0dd101c7fa71f9042a59.
2. Attacker crafts a malicious HTTP GET request targeting the buslocation.php file.
3. The malicious request includes the bus_id parameter containing a SQL injection payload designed to manipulate the database query.
4. The application fails to properly sanitize the bus_id parameter.
5. The application executes the crafted SQL query, incorporating the attacker's malicious SQL code.
6. Depending on the injected SQL, the attacker can read sensitive data, modify database contents, or potentially execute arbitrary commands on the database server.
7. The attacker exfiltrates sensitive data or uses the compromised database as a pivot point for further attacks on the internal network.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-6595) could allow an attacker to gain unauthorized access to sensitive information stored in the school management system database, including student records, financial data, and administrative credentials. This could lead to data breaches, identity theft, financial fraud, and reputational damage. Given the nature of the application, a successful attack could severely impact the privacy and security of students, parents, and staff.

Recommendation

• Inspect web server access logs for requests to buslocation.php containing suspicious characters or SQL syntax in the bus_id parameter (see example Sigma rule).
• Deploy a web application firewall (WAF) rule to block requests to buslocation.php with potentially malicious SQL injection payloads in the bus_id parameter.
• Apply input validation and sanitization to the bus_id parameter in buslocation.php to prevent SQL injection. Since a patch is unavailable, this may require custom code modifications.
