Malformed Device Reset Locally command classes can be sent to temporarily deny service to an end device. Any frames sent by the end device will not be acknowledged by the gateway during this time.

Malformed S2 Nonce Get command classes can be sent to crash the gateway. A hard reset is required to recover the gateway.

The first S0 encryption key is generated with an uninitialized PRNG in Z/IP Gateway products running Silicon Labs Z/IP Gateway SDK v7.18.3 and earlier. This makes the first S0 key generated at startup predictable, potentially allowing network key pre...

Description: A vulnerability in SiLabs Z/IP Gateway 7.18.01 and earlier allows an unauthenticated attacker within Z-Wave range to overflow a stack buffer, leading to arbitrary code execution.

A vulnerability in SiLabs Z/IP Gateway 7.18.01 and earlier allows an authenticated attacker within Z-Wave range to manipulate an array pointer to disclose the contents of global memory.

Multiple buffer overflow vulnerabilities in SiLabs Z/IP Gateway SDK version 7.18.01 and earlier allow an attacker with invasive physical access to a Z-Wave controller device to overwrite global memory and potentially execute arbitrary code.

A logic error in SiLabs Z/IP Gateway SDK 7.18.02 and earlier allows authentication to be bypassed, remote administration of Z-Wave controllers, and S0/S2 encryption keys to be recovered.
