CWE-110 Structs：无表单域的验证器
Struts: Validator Without Form Field
结构: Simple
Abstraction: Variant
状态: Draft
被利用可能性: unkown
基本描述
Validation fields that do not appear in forms they are associated with indicate that the validation logic is out of date.
扩展描述
It is easy for developers to forget to update validation logic when they make changes to an ActionForm class. One indication that validation logic is not being properly maintained is inconsistencies between the action form and the validation form.
Although J2EE applications are not generally susceptible to memory corruption attacks, if a J2EE application interfaces with native code that does not perform array bounds checking, an attacker may be able to use an input validation mistake in the J2EE application to launch a buffer overflow attack.

| Other | Other | It is critically important that validation logic be maintained and kept in sync with the rest of the application. Unchecked input is the root cause of some of today's worst and most common software security problems. Cross-site scripting, SQL injection, and process control vulnerabilities all stem from incomplete or absent input validation. |

示例代码
例
This example shows an inconsistency between an action form and a validation form. with a third field.
This first block of code shows an action form that has two fields, startDate and endDate.
bad Java
public void setStartDate(String startDate) {
}
public void setEndDate(String endDate) {
}
}
This second block of related code shows a validation form with a third field: scale. The presence of the third field suggests that DateRangeForm was modified without taking validation into account.
bad XML
