Attack Chain

1. An attacker identifies a vulnerable instance of student_management_system_by_php running a version up to 310d950e09013d5133c6b9210aff9444382d16d1.
2. The attacker crafts a malicious HTTP request targeting the delete.php endpoint.
3. The attacker injects SQL code into one or more of the following parameters: user_id, course_id, teacher_id, student_id, or application_id.
4. The web server processes the delete.php script, passing the attacker-controlled input to a vulnerable SQL query without proper sanitization.
5. The injected SQL code modifies the query’s behavior, potentially allowing the attacker to bypass authentication or access sensitive data.
6. The database server executes the modified SQL query, performing actions unintended by the application developer.
7. The attacker gains unauthorized access to sensitive information stored in the database.
8. The attacker may be able to further escalate the attack, potentially gaining complete control over the database server or the web application.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-10226) can lead to unauthorized access to sensitive student data, including personally identifiable information (PII), academic records, and financial information. This could result in data breaches, identity theft, and financial losses for both the institution and its students. The impact can range from defacement of the application to complete compromise of the underlying database server.

Recommendation

• Inspect web server logs for suspicious requests to delete.php with potentially malicious characters in the user_id, course_id, teacher_id, student_id, and application_id parameters, as described in the overview. Implement the Sigma rule Detect SQL Injection Attempt in student_management_system_by_php delete.php.
• Apply input validation and sanitization to all user-supplied data, especially in the delete.php script, to prevent SQL injection attacks.
• Consider using parameterized queries or stored procedures to prevent SQL injection vulnerabilities within the application.
• Monitor database logs for anomalous activity that could indicate successful SQL injection attempts.
• Since there are no version details available, any deployment of student_management_system_by_php should be considered vulnerable.
