界: API Abuse

API 是调用方和被调用方之间的约定。最常见的 API 滥用是由于调用方未能遵守此约定的终止导致的。例如，如果某个程序在调用 chroot() 后未能调用 chdir()，则违反了用于指定如何安全地更改活动根目录的约定。库滥用的另一个典型示例是期望被调用方向调用方返回可信的 DNS 信息。在这种情况下，调用方通过对被调用方行为做出某种假设（返回值可用于身份验证目的）滥用其 API。另一方也可能违反调用方-被调用方约定。例如，如果编码器子类化 SecureRandom 并返回一个非随机值，则将违反此约定。

Often Misused: Android Permission Check

Java/JSP

Abstract

应谨慎使用 checkCallingOrSelfPermission() 或 checkCallingOrSelfUriPermission() 函数，因为它允许调用程序在没有所需权限或没有权限的情况下，通过使用应用程序的权限绕过权限检查。

Explanation

函数 checkCallingOrSelfPermission() 或 checkCallingOrSelfUriPermission() 用来判定调用程序是否具备访问某个服务或给定 URI 所需的权限。但是，由于此类函数可允许缺乏相应权限的恶意应用程序利用您应用程序的权限进行访问，因而应慎重使用。

这意味着没有相应权限的恶意应用程序可以利用您应用程序的权限来避开它的权限检查，以获得对本应拒绝其访问的资源的访问。这可能导致所称的混淆代理人攻击。
