CWE-602—Client-Side Enforcement of Server-Side Security

名称

Client-Side Enforcement of Server-Side Security

描述

The product is composed of a server that relies on the client to implement a mechanism that is intended to protect the server.

When the server relies on protection mechanisms placed on the client side, an attacker can modify the client-side behavior to bypass the protection mechanisms, resulting in potentially unexpected interactions between the client and server. The consequences will vary, depending on what the mechanisms are trying to protect.

常见后果

范围：

Access Control, Availability

影响：

Bypass Protection Mechanism, DoS: Crash, Exit, or Restart

注释：

Client-side validation checks can be easily bypassed, allowing malformed or unexpected input to pass into the application, potentially as trusted data. This may lead to unexpected states, behaviors and possibly a resulting crash.

范围：

Access Control

影响：

Bypass Protection Mechanism, Gain Privileges or Assume Identity

注释：

Client-side checks for authentication can be easily bypassed, allowing clients to escalate their access levels and perform unintended actions.
