A vulnerability, which was classified as critical, has been found in Insteon Hub 1012 (Network Management Software). Affected by this issue is an unknown code block of the component PubNub Message Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to 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). Impacted is confidentiality, integrity, and availability. CVE summarizes:

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 s_utc, at 0x9d0193ac, the value for the `offset` key is copied using `strcpy` to the buffer at `$sp+0x2d0`.This buffer is 100 bytes large, sending anything longer will cause a buffer overflow.

The weakness was published 01/12/2023 as TALOS-2017-0483. The advisory is available at talosintelligence.com. This vulnerability is handled as CVE-2017-16289 since 10/31/2017. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 02/04/2023).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
