A vulnerability classified as critical was found in Insteon Hub 1012 (Network Management Software). Affected by this vulnerability is some unknown functionality of the component PubNub Message Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Multiple exploitable buffer overflow vulnerabilities exist in the PubNub message handler for the "cc" channel of Insteon Hub running 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. In cmd g_b, at 0x9d015714, the value for the `grp` key is copied using `strcpy` to the buffer at `$sp+0x280`.This buffer is 16 bytes large, sending anything longer will cause a buffer overflow.

The weakness was presented 01/12/2023 as TALOS-2017-0483. It is possible to read the advisory at talosintelligence.com. This vulnerability is known as CVE-2017-16261 since 10/31/2017.
