CWE-603: Use of Client-Side Authentication
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
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.
扩展描述
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.
常见后果
影响范围: Access Control
技术影响: Bypass Protection Mechanism Gain Privileges or Assume Identity
潜在缓解措施
阶段: Architecture and Design
描述: Do not rely on client side data. Always perform server side authentication.
观察示例
参考: CVE-2022-33139
SCADA system only uses client-side authentication, allowing adversaries to impersonate other users.
参考: CVE-2006-0230
Client-side check for a password allows access to a server using crafted XML requests from a modified client.
