A vulnerability was found in Insteon Hub 2245-222 1012 (Network Management Software). It has been rated as critical. This issue affects an unknown code of the component PubNub Service. The manipulation of the argument ak as part of a GET Request leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

On Insteon Hub 2245-222 devices with firmware version 1012, specially crafted replies received from the PubNub service can cause buffer overflows on a global section overwriting arbitrary data. An attacker should impersonate PubNub and answer an HTTPS GET request to trigger this vulnerability. A strcpy overflows the buffer insteon_pubnub.channel_ak, which has a size of 16 bytes. An attacker can send an arbitrarily long "ak" parameter in order to exploit this vulnerability.
