sleep 延遲注入

發布時間:2020-06-29 15:30:12 來源:網絡 閱讀:1269 作者:lilei754212328 欄目:安全技術

A:     時間差注入也叫延遲注入,是一種盲注的手法   提交對執行時間銘感的函數sql語句,通過執行時間的長短來判斷是否執行成功,比如:正確的話會導致時間很長,錯誤的話會導致執行時間很短,這就是所謂的高級盲注。
     利用BENCHMARK sleep 函數來注入
     利用sleep也可以引起拒絕服務

B:

有時候當我們注入某站時,某站突然就打不開了,

被防火墻暫時隔離,你沒法瀏覽他的頁面,這時候你不得不換換IP,或者等待恢復,

或者提交注入參數的時候,網站的某種保護措施,他會跳轉某個錯誤頁面,訪問N次錯誤頁面的時候,才會正常訪問。

這樣就會影響咱們的效率,這就是為什么延時注入也算一節課的原因,還是蠻重要的.
