Instance Method Details

#test_vulnerable ⇒ Boolean

This method checks if the target is vulnerable to Blind time-based injection by checking if the target sleeps only when a given condition is true, and doesn’t when it’s false.

Returns:

  • (Boolean) —

    Whether the check confirmed that the time-based SQL injection works
