CVE-2017-16337
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
