CWE-420 未保护的候选通道 类漏洞列表 36

CWE-420 未保护的候选通道 类弱点 36 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-420 指未受保护的备用通道漏洞,属于安全配置缺陷。当产品仅保护主通信通道而忽视备用通道时,攻击者会利用该差异,通过未加密或弱认证的备用接口窃取敏感数据或执行未授权操作。开发者应避免此风险,需确保所有通信路径采用一致且高强度的加密与认证机制,实施全面的安全策略,消除保护盲区。

MITRE CWE 官方描述
CWE:CWE-420 Unprotected Alternate Channel(未受保护的备用通道) 英文:The product protects a primary channel, but it does not use the same level of protection for an alternate channel. 译文:产品对主通道(primary channel)进行了保护,但未对备用通道(alternate channel)采用同等级别的保护。
常见影响 (1)
Access Control Gain Privileges or Assume Identity, Bypass Protection Mechanism
缓解措施 (1)
Architecture and Design Identify all alternate channels and use the same protection mechanisms that are used for the primary channels.

Register SECURE_ME is located at address 0xF00. A mirror of this register called COPY_OF_SECURE_ME is at location 0x800F00. The register SECURE_ME is protected from malicious agents and only allows access to select, while COPY_OF_SECURE_ME is not. Access control is implemented using an allowlist (as indicated by a…
