Insteon Hub 2245-222 Firmware 1012

An exploitable information leak vulnerability exists in Insteon Hub running firmware version 1012. The HTTP server implementation incorrectly checks the number of GET parameters supplied, leading to an arbitrarily controlled information leak on the whole device memory. An attacker can send an authenticated HTTP request to trigger this vulnerability.

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.

On Insteon Hub 2245-222 devices with firmware version 1012, specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability. At 0x9d01ef24 the value for the s_offset key is copied using strcpy to the buffer at $sp+0x2b0. This buffer is 32 bytes large, sending anything longer will cause a buffer overflow.

An attacker should impersonate PubNub and answer an HTTPS GET request to trigger this vulnerability. A strcpy overflows the buffer insteon_pubnub.channel_ad_r, which has a size of 16 bytes. An attacker can send an arbitrarily long "ad_r" parameter in order to exploit this vulnerability.
