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 is an unauthenticated SQL injection vulnerability in the Online Examination System (OES) affecting the results.php file. The issue stems from unvalidated GET parameters id and user, and POST parameter topic, which are directly concatenated into SQL queries without sanitization. The database user is configured as root by default.

Detection Guidance

To detect this SQL injection vulnerability, monitor network traffic for suspicious GET/POST requests to results.php with parameters id, user, or topic. Use tools like sqlmap to test for SQLi by sending crafted payloads such as id=1' OR '1'='1 or user=admin'--. Check database logs for unusual queries or errors indicating SQL syntax issues.

Impact Analysis

An attacker can remotely exploit this to extract arbitrary data from the exam_res table without authentication. This includes sensitive information like exam results or user data. The vulnerability allows both boolean-based blind and in-band SQL injection attacks.

Compliance Impact

This vulnerability could lead to unauthorized access and exposure of sensitive personal data, violating GDPR and HIPAA requirements for data protection and confidentiality. Non-compliance may result in legal penalties and reputational damage.

Mitigation Strategies

Immediately update the Online Examination System to the latest version or apply patches from the vendor. Implement input validation and parameterized queries for id, user, and topic parameters. Disable direct SQL query concatenation and restrict database user privileges to limit damage from potential exploits.
