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。

Deserialization Bad Practice: Deny List

Java/JSP

Abstract

以阻止還原序列化已知錯誤類別 (拒絕清單) 為基礎的防禦還原序列化，可能會讓攻擊者避開此保護並使保護不起作用。

Explanation

應用程式會實作稱為「前瞻式還原序列化」的防禦還原序列化技術，這種技術允許應用程式在還原序列化類別真正還原序列化之前進行預覽。

利用一些新的小工具鏈、封裝的封包或類別在其還原序列化回呼中執行巢狀還原序列化，可輕鬆避開拒絕清單。
