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。
Bean Manipulation
Abstract
攻擊者可設定可能危及系統完整性的任意 bean 屬性。
Explanation
Bean 屬性名稱和值在填入任何 bean 之前皆需驗證。Bean 填寫功能允許開發人員設定 bean 屬性或巢狀屬性。攻擊者可利用此功能存取類似於
範例：以下程式碼會設定使用者控制的 bean 屬性，但不正常驗證屬性名稱或值：
class.classLoader 的特別 bean 屬性，這些屬性允許攻擊者取代系統屬性，並可能執行任意程式碼。範例：以下程式碼會設定使用者控制的 bean 屬性，但不正常驗證屬性名稱或值：
String prop = request.getParameter('prop');
String value = request.getParameter('value');
HashMap properties = new HashMap();
properties.put(prop, value);
BeanUtils.populate(user, properties);
