CWE ID Description
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.
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.

Executive Summary

This vulnerability is a SQL injection found in the Class and Exam Timetabling System version 1.0, specifically in the /edit_exam.php file. It occurs because the 'id' parameter is not properly validated, allowing attackers to inject malicious SQL queries.

Through this flaw, attackers can execute unauthorized database commands, potentially accessing, modifying, or deleting sensitive data without needing to log in.

Various types of SQL injection attacks are possible, including boolean-based blind, error-based, time-based blind, and UNION query attacks.

Impact Analysis

This vulnerability can lead to unauthorized access to the database, allowing attackers to view, alter, or delete sensitive information.

It compromises data integrity and system security, potentially resulting in data tampering and leakage of confidential information.

Since the attack can be performed remotely without authentication, it increases the risk of system compromise and unauthorized control.

Detection Guidance

This SQL injection vulnerability in the /edit_exam.php file can be detected by testing the 'id' parameter for SQL injection flaws using various payloads such as boolean-based blind, error-based, time-based blind, and UNION query attacks.

Common detection methods include sending crafted HTTP requests to the vulnerable endpoint with SQL injection payloads and observing the responses for anomalies or errors indicating injection.

  • Use tools like sqlmap to automate detection: sqlmap -u "http://target/edit_exam.php?id=1" --batch
  • Manually test with payloads such as '1 OR 1=1', '1' UNION SELECT NULL--, or time delays like '1' WAITFOR DELAY '0:0:5'-- in the 'id' parameter.
Mitigation Strategies

Immediate mitigation steps include implementing prepared statements with parameter binding to prevent SQL injection.

Strict input validation on the 'id' parameter should be enforced to ensure only expected data types and values are accepted.

Minimize database user permissions to limit the potential impact of an injection attack.

Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.

Compliance Impact

The SQL injection vulnerability in the Class and Exam Timetabling System allows unauthorized database access, data tampering, and sensitive information leakage. Such unauthorized access and potential exposure of sensitive data can lead to non-compliance with data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access and breaches.

Failure to address this vulnerability could result in violations of confidentiality, integrity, and availability principles mandated by these standards, potentially leading to legal and financial consequences.
