CVE-2026-108473— 多个TP-Link Kasa设备认证缺陷与凭证泄露漏洞
一分钟漏洞结论
影响对象
TP-Link Systems Inc. HS103 v5
利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
多个Kasa设备在其本地设备管理协议中存在不正确的身份验证漏洞。未经身份验证的相邻网络攻击者可以在无需充分认证或授权的情况下，向受影响设备发送管理指令，从而能够修改设备状态或管理设置。在某些涉及用户、移动应用与设备-云服务交互的使用条件下，对账户相关通信的保护不足还可能暴露账户信息。 成功利用该漏洞可能使未经身份验证的相邻网络攻击者执行未授权的设备管理操作，并破坏合法用户的控制权。在特定条件下，账户相关信息也可能被暴露，进而可能导致关联云账户被入侵。

Vulnerability Title
Improper Authentication and Credential Exposure in Multiple TP-Link Kasa Devices
来源: CVE Program / CVE List V5
Vulnerability Description
Multiple
Kasa devices contain an improper authentication vulnerability in the local
device-management protocol. An unauthenticated adjacent attacker may send
management instructions to an affected device without adequate authentication
or authorization, allowing modification of the device state or management
settings. Under certain usage conditions involving interaction between the
user, mobile application, and device-cloud service, insufficient protection of
account-related communications may also expose account information.
Successful
exploitation may allow an unauthenticated adjacent-network attacker to perform
unauthorized device-management actions and disrupt legitimate user control.
Under certain conditions, account-related information may also be exposed,
potentially leading to compromise of the associated cloud account.
