|---|---|---|
| Integrity | Modify Application Data | The contents of the array can be modified from outside the intended scope. |
可能的缓解方案
Implementation
策略:
Do not allow objects to modify private members of a class.
示例代码
例
In the example below, the setRoles() method assigns a publically-controllable array to a private field, thus allowing the caller to modify the private array directly by virtue of the fact that arrays in Java are mutable.
bad Java
private String[] userRoles;
public void setUserRoles(String[] userRoles) {
public void setUserRoles(String[] userRoles) {
this.userRoles = userRoles;
}
