CVE-2022-32504
The code used to parse the JSON objects received from the WebSocket service provided by the device leads to a stack buffer overflow.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered on certain Nuki Home Solutions devices. The code used to parse the JSON objects received from the WebSocket service provided by the device leads to a stack buffer overflow. An attacker would be able to exploit this to gain arbitrary code execution on a KeyTurner device. This affects Nuki Smart Lock 3.0 before 3.3.5 and 2.0 before 2.12.4, as well as Nuki Bridge v1 before 1.22.0 and v2 before 2.13.2.
