Instance Method Summary

• #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.

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
