Detailsinfo

A vulnerability was found in Insteon Hub 1012 (Network Management Software). It has been classified as critical. This affects an unknown code block of the component PubNub Message Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as 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). This is going to have an impact on 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 sn_sx, at 0x9d014f28, the value for the `cmd3` 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.

The weakness was shared 01/12/2023 as TALOS-2017-0483. It is possible to read the advisory at talosintelligence.com. This vulnerability is uniquely identified as CVE-2017-16257 since 10/31/2017.
