界: Input Validation and Representation

輸入驗證和表示法問題是由中繼字元、替代編碼和數值表示法引起的。信任輸入會導致安全問題。問題包括：「Buffer Overflows」、「Cross-Site Scripting」攻擊、「SQL Injection」及其他許多問題。

Struts: Form Does Not Extend Validation Class

Java/JSP

Abstract

所有的 Struts 表單應該要延伸 Validator 類別。

Explanation

為了能夠使用 Struts Validator，表單必須延伸以下其中一個項目：


ValidatorForm
ValidatorActionForm
DynaValidatorActionForm
DynaValidaorForm

您必須延伸這些類別中的其中一個，因為 Struts Validator 是透過在這些類別中執行 validate() 方法，而與應用程式連結。

源自下面類別的表單不能使用 Struts Validator：


ActionForm
DynaActionForm

略過表單的驗證框架將使應用程式暴露於各種攻擊之下。未經驗證的輸入是導致各種弱點的根源，如 cross-site scripting、process control 和 SQL injection。雖然 J2EE 應用程式在通常情況下不容易因記憶體損壞攻擊而受到影響，但是如果 J2EE 應用程式連接到未執行陣列界限檢查的本地程式碼，攻擊者就能夠在 J2EE 應用程式中利用輸入驗證錯誤發起 Buffer overflow 攻擊。
