Key Information The Issue Vulnerability Type: SQL Injection Affected File: Cause: User input not properly validated or escaped, allowing SQL queries to be manipulated. The Explanation Root Cause: Improper handling of user input by the application. Code Example: Variables: and are directly sourced from user input, without adequate validation or escaping. Proof of Vulnerability Testing Tool: sqlmap Command: Result: Time-based blind SQL injection successfully exploited. Steps to Reproduce 1. Intercept the request to . 2. Inject an SQL payload into the parameter. 3. Observe delayed response to confirm successful time-based blind injection. 4. Use tools like sqlmap to further explore the database. Notes Risk: Critical security risk; immediate remediation required. Recommendation: Use prepared statements or parameterized queries; ensure proper validation and escaping of user input.
