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 Student Registration System version 1.0 or earlier. It exists in the changepass.php file where user input from the 'opwd' parameter is directly used in SQL queries without proper sanitization. Attackers can inject malicious SQL code to manipulate queries, potentially accessing or altering sensitive data like passwords.

Detection Guidance

To detect this SQL injection vulnerability, test the changepass.php file by sending crafted input to the 'opwd' parameter. Use tools like SQLmap to automate detection with commands such as: sqlmap -u 'http://target.com/student/changepass.php' --data='opwd=test' --batch. Manually, try injecting time delays with payloads like 'opwd=1' OR SLEEP(5)--' to observe database response times.

Check server logs for unusual SQL query patterns or errors indicating injection attempts. Monitor network traffic for suspicious payloads targeting the 'opwd' parameter.

Impact Analysis

This vulnerability could allow remote attackers to execute unauthorized SQL commands on the database. This may lead to unauthorized access to sensitive information such as user credentials, personal data, or administrative privileges. Attackers could also manipulate or delete data, disrupt services, or escalate their access within the system.

Compliance Impact

This vulnerability likely violates compliance requirements under GDPR and HIPAA due to unauthorized data access and potential exposure of sensitive personal information. GDPR mandates strict data protection and breach notification, while HIPAA requires safeguards for protected health information. Exploitation could result in regulatory penalties and legal consequences.

Mitigation Strategies

Immediately update the Student Registration System to a patched version if available. Implement prepared statements for all SQL queries involving user input. Validate and sanitize the 'opwd' parameter to reject non-alphanumeric characters. Restrict database user privileges to limit potential damage from exploitation.

Apply web application firewalls to filter malicious SQL payloads. Conduct a security audit to identify other potential injection points. Monitor systems for signs of compromise, such as unauthorized data access or modifications.
