界: Input Validation and Representation

输入验证与表示问题是由元字符、交替编码和数字表示引起的。安全问题源于信任输入。这些问题包括：“Buffer Overflows”、“Cross-Site Scripting”攻击、“SQL Injection”等其他问题。

OGNL Expression Injection: Dynamic Method Invocation

Java/JSP

Abstract

Struts 2 应用程序启用动态方法调用，众所周知，在某些 Struts 2 版本中，很容易受到 OGNL Injection 攻击。

Explanation

Struts 2 引入了名为“动态方法调用”的功能，允许操作公开 execute() 以外的方法。如果启用“动态方法调用”，可在操作 URL 中使用 ! (bang) 字符或 method: 前缀，以在操作中调用任何公共方法。在 Struts 2 版本 2.3.20 中，先前基于反映调用替代方法的机制将替换为使用 OGNL，这样攻击者将可以提供恶意 OGNL 表达式而不是替代方法名称。
