CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This vulnerability is a SQL injection flaw in the School Registration and Fee System 1.0. It exists in the pay_report.php file where the 'period' parameter is improperly validated. Attackers can inject malicious SQL code through this parameter without needing authentication. This allows them to manipulate database queries, potentially accessing, altering, or deleting sensitive data.

Detection Guidance

To detect this SQL injection vulnerability, you can use tools like sqlmap to test the 'period' parameter in the /bilal/normal/pay_report.php file. Example command: sqlmap -u 'http://target-site/bilal/normal/pay_report.php?period=1' --batch. Manual testing can also be done by appending SQL payloads to the parameter and observing error messages or unexpected behavior.

Check web server logs for unusual queries or patterns in requests to /bilal/normal/pay_report.php. Look for strings like 'UNION SELECT', 'WAITFOR DELAY', or other SQL syntax in input parameters.

Impact Analysis

This vulnerability can lead to unauthorized access to sensitive data such as student records, financial information, or personal details. Attackers could modify or delete data, disrupt system operations, or gain control of the database server. Exploitation could also enable further attacks like data exfiltration or system compromise.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized data access or leakage. GDPR requires protection of personal data, while HIPAA mandates safeguards for health-related information. A breach could result in legal penalties, fines, and reputational damage for organizations handling sensitive data.

Mitigation Strategies

Immediately update the application to use prepared statements with parameterized queries for all database interactions. Validate and sanitize all user inputs, especially the 'period' parameter, to reject any non-numeric or suspicious values.

Restrict database user permissions to the minimum required for functionality. Avoid using root or admin accounts for application queries. Conduct a security audit to identify and fix similar vulnerabilities in other parts of the system.
