CAPEC 描述

An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.

CAPEC 信息

前提条件

Server software must rely on client side formatted and validated values, and not reinforce these checks on the server side.

所需技能

The attacker must have fairly detailed knowledge of the syntax and semantics of client/server communications protocols and grammars

所需资源

Ability to communicate synchronously or asynchronously with server

缓解措施

Design: Ensure that client process and/or message is authenticated so that anonymous communications and/or messages are not accepted by the system.
Design: Do not rely on client validation or encoding for security purposes.
Design: Utilize digital signatures to increase authentication assurance.
Design: Utilize two factor authentication to increase authentication assurance.
Implementation: Perform input validation for all remote content.

相关弱点

CWE-ID 弱点名称

CWE-290

Authentication Bypass by Spoofing
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.

CWE-287

Improper Authentication
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

CWE-20

Improper Input Validation
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

CWE-200

Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

CWE-693

Protection Mechanism Failure
The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.
