CVE-2017-14454
Multiple exploitable buffer overflow vulnerabilities exists in the PubNub message handler for the "control" channel of Insteon Hub running firmware version 1012.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.60%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Multiple exploitable buffer overflow vulnerabilities exists in the PubNub message handler for the "control" channel of Insteon Hub running 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. The `strcpy` at [18] overflows the buffer `insteon_pubnub.channel_al`, which has a size of 16 bytes.
