            J2EE Misconfiguration: Missing Error Handling

            ABSTRACT

            Web 應用程序必須定義默認的錯誤頁面,以避免攻擊者通過應用程序容器的內置錯誤響應來挖掘信息。

            EXPLANATION

            當攻擊者瀏覽網站尋找漏洞時,站點提供信息的數量是攻擊成敗的關鍵。如果應用程序向攻擊者展示了堆棧蹤跡,那么堆棧釋放的信息將使攻擊者的攻擊變得輕而易舉。例如,一個堆棧跟蹤可能會給攻擊者顯示 SQL 查詢字串、即使用的數據庫類型以及應用程序容器的版本。攻擊者可以從這些信息中找到這些組件中存在的漏洞。

            因此,應用程序應通過配置來指定一個默認的錯誤頁面,以保證應用程序永遠不會向攻擊者泄漏錯誤消息。處理標準 HTTP 錯誤代碼是一種簡單、有效、安全的做法;完善的配置還會定義一個用于補救的錯誤處理程序,來捕獲應用程序可能拋出的所有異常。
