Use of Client-Side Authentication

A client/server product performs authentication within client code but not in server code, allowing server-side authentication to be bypassed via a modified client that omits the authentication check.

Extended Description

Client-side authentication is extremely weak and may be breached easily. Any attacker may read the source code and reverse-engineer the authentication mechanism to access parts of the application which would otherwise be protected.

Informations

Modes Of Introduction

Architecture and Design : COMMISSION: This weakness refers to an incorrect design related to an architectural security tactic.
Implementation

Applicable Platforms

Language

Class: Not Language-Specific (Undetermined)

Technologies

Class: ICS/OT (Undetermined)

Common Consequences

Scope Impact Likelihood
Access ControlBypass Protection Mechanism, Gain Privileges or Assume Identity

Observed Examples

Reference Description
CVE-2022-33139SCADA system only uses client-side authentication, allowing adversaries to impersonate other users.
CVE-2006-0230Client-side check for a password allows access to a server using crafted XML requests from a modified client.

Potential Mitigations

Phases : Architecture and Design
Do not rely on client side data. Always perform server side authentication.

Vulnerability Mapping Notes

Rationale : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comments : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
