CWE-102 Structs：重复验证表单

Struts: Duplicate Validation Forms

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

The application uses multiple validation forms with the same name, which might cause the Struts Validator to validate a form that the programmer does not expect.

扩展描述

If two validation forms have the same name, the Struts Validator arbitrarily chooses one of the forms to use for input validation and discards the other. This decision might not correspond to the programmer's expectations, possibly leading to resultant weaknesses. Moreover, it indicates that the validation logic is not up-to-date, and can indicate that other, more subtle validation errors are present.

常见的影响

可能的缓解方案

Implementation

策略:

The DTD or schema validation will not catch the duplicate occurrence of the same form name. To find the issue in the implementation, manual checks or automated static analysis could be applied to the xml configuration files.

示例代码

例

Two validation forms with the same name.

bad XML

It is critically important that validation logic be maintained and kept in sync with the rest of the application.
