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 file /bilal/normal/delete_stud.php due to improper input validation of the 'selector[]' parameter. Attackers can inject malicious SQL queries through this parameter, enabling unauthorized database access and data tampering without requiring login or authorization.

Detection Guidance

To detect this SQL injection vulnerability, test the /bilal/normal/delete_stud.php endpoint with payloads targeting the selector[] parameter. Use tools like SQLmap with: sqlmap -u "http://target.com/bilal/normal/delete_stud.php?selector[]=1" --data="selector[]=1" --batch --risk=3 --level=5. Alternatively, manually test with payloads like ' OR 1=1 -- or 3' AND (SELECT 2083 FROM (SELECT(SLEEP(5)))BJmC)-- CwHZ.

Monitor for unusual database query delays or errors in logs. Check for repeated requests to the vulnerable endpoint with varying inputs.

Impact Analysis

This vulnerability allows attackers to manipulate the database by injecting malicious SQL queries. This can lead to unauthorized access to sensitive data, data tampering, or even complete system compromise. The attack can be executed remotely without authentication.

Compliance Impact

This vulnerability can lead to unauthorized access and leakage of sensitive data, which may violate compliance requirements under GDPR and HIPAA. GDPR requires protection of personal data, while HIPAA mandates safeguards for protected health information. A breach could result in legal penalties and reputational damage.

Mitigation Strategies

Immediately update the delete_stud.php file to use prepared statements for all database queries. Implement strict input validation to sanitize the selector[] parameter. Restrict database user permissions to least privilege. Conduct a full security audit of the application.

Apply patches or updates from the vendor if available. Monitor network traffic for signs of exploitation attempts. Consider temporarily disabling the vulnerable endpoint if mitigation cannot be applied immediately.
