Struts: Validator Turned Off

ABSTRACT

這個 action form 映射禁用了表單的 validate()方法。

EXPLANATION

action form 映射永遠不應該禁用驗證。禁用驗證的同時也就禁用了 Struts Validator，一并還有所有由表單執行的自定義驗證邏輯。

示例：一個禁用了驗證的 action form 映射。

<action path="/download"
type="com.website.d2.action.DownloadAction"
name="downloadForm"
scope="request"
input=".download"
validate="false">
</action>

禁用驗證會使該操作暴露在各種攻擊之下。未經校驗的輸入是導致各種漏洞的根源，如 cross-site scripting、process control 和 SQL injection。雖然 J2EE 應用程序通常情況下不容易受到內存損壞的影響，但是如果 J2EE 應用程序連接到未執行數組邊界檢查的本地代碼，攻擊者就可能會利用 J2EE 應用程序中一個輸入校驗錯誤發起 buffer overflow 攻擊。
