软件安全不是安全软件。此处我们关注的主题包括身份验证、Access Control、机密性、加密和权限管理。

Permission Manipulation

Abstract
允许用户输入以直接更改权限可能导致攻击者能够访问以其他方式保护的系统资源。
Explanation
如果攻击者能够修改应用程序中用于确定权限的值,则会出现权限操纵错误。

示例 1:以下代码使用来自文件的输入确定应用程序中所需的 FileIOPermissions


...
String permissionsXml = GetPermissionsFromXmlFile();
FileIOPermission perm = new FileIOPermission(PermissionState.None);
perm.FromXml(permissionsXml);
perm.Demand();
...


在这种情况下,如果用户能够控制用于检索数据的 XML 文件,则他们可控制系统可能要求的权限。
