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: sun.misc.Unsafe

Java/JSP

Abstract

应用程序使用 sun.misc.Unsafe 中的功能。此类中的所有功能本质上均不安全，只能通过反射进行访问。

Explanation

sun.misc.Unsafe 类用于执行不安全的低级操作，不适合开发人员使用。
Unsafe 类只能通过受信任代码获取，且通常通过反射获取，因为其可用来破坏系统或手动分配堆内存，如果处理不当，可能会对系统产生不利影响。必须仔细检查和测试与 sun.misc.Unsafe 相关的所有功能，确保不出现错误。
