Authenticated Thread Attacker Causes Device Denial of Service via OpenThread MLE Packet Vulnerabilities

Multiple vulnerabilities exist in OpenThread's handling of MLE packets. An authenticated attacker on the same Thread network could send specially crafted packets to cause a denial of service. These issues include triggerable assertion failures and a stack-based buffer overflow.

Unchecked length in Trusted Application on Google Nest Wifi Pro, leading to out of bounds read

Due to length check, an attacker with privilege access on a Linux Nonsecure operating system can trigger a vulnerability and leak the secure memory from the Trusted Application

U-Boot environment is read from unauthenticated partition.

According to the researcher: "The TLS connections are encrypted against tampering or eavesdropping. However, the application does not validate the server certificate properly while initializing the TLS connection. This allows for a network attacker to intercept the connection and read the data. The attacker could the either send the client a malicious response, or forward the (possibly modified) data to the real server."

Google Nest WiFi Pro root code-execution & user-data compromise

Google Nest WiFi Pro root code-execution & user-data compromise

The libcurl CURLOPT_SSL_VERIFYPEER option was disabled on a subset of requests made by Nest production devices which enabled a potential man-in-the-middle attack on requests to Google cloud services by any host the traffic was routed through.

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.

An exploitable denial-of-service vulnerability exists in the Weave daemon of the Nest Cam IQ Indoor, version 4620002. A set of TCP connections can cause unrestricted resource allocation, resulting in a denial of service. An attacker can connect multiple times to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the Weave MessageLayer parsing of Openweave-core version 4.0.2 and Nest Cam IQ Indoor version 4620002. A specially crafted weave packet can cause an integer overflow to occur, resulting in PacketBuffer data reuse. An attacker can send a packet to trigger this vulnerability.

An exploitable denial-of-service vulnerability exists in the Weave certificate loading functionality of Nest Cam IQ Indoor camera, version 4620002. A specially crafted weave packet can cause an integer overflow and an out-of-bounds read on unmapped memory to occur, resulting in a denial of service. An attacker can send a specially crafted packet to trigger.

An exploitable denial-of-service vulnerability exists in the Weave error reporting functionality of the Nest Cam IQ Indoor, version 4620002. A specially crafted weave packets can cause an arbitrary Weave Exchange Session to close, resulting in a denial of service. An attacker can send a specially crafted packet to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the Weave PASE pairing functionality of the Nest Cam IQ Indoor, version 4620002. A set of specially crafted weave packets can brute force a pairing code, resulting in greater Weave access and potentially full device control. An attacker can send specially crafted packets to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the Weave Legacy Pairing functionality of Nest Cam IQ Indoor version 4620002. A set of specially crafted weave packets can cause an out of bounds read, resulting in information disclosure. An attacker can send packets to trigger this vulnerability.
