Authentication Bypass in OpenThread Boarder Router devices

There exists an authentication bypass vulnerability in OpenThread border router devices and implementations. This issue allows unauthenticated nodes to craft radio frames using “Key ID Mode 2”: a special mode using a static encryption key to bypass security checks, resulting in arbitrary IP packets being allowed on the Thread network. This provides a pathway for an attacker to send/receive arbitrary IPv6 packets to devices on the LAN, potentially exploiting them if they lack additional authentication or contain any network vulnerabilities that would normally be mitigated by the home router’s NAT firewall. Effected devices have been mitigated through an automatic update beyond the affected range.

Google Nest 授权问题漏洞

Google Nest是美国谷歌（Google）公司的一款智能家居产品。 Google Nest存在安全漏洞。该漏洞允许未经身份验证的节点使用“Key ID Mode 2”来伪造无线电帧，这是一种使用静态加密密钥绕过安全检查的特殊模式，从而允许任意 IP 数据包传输到 Thread 网络中。
