A vulnerability was found in Insteon Hub 1012 (Network Management Software). It has been rated as critical. This issue affects an unknown functionality of the component HTTP Server. The manipulation of the argument sn_speaker as part of a HTTP Request leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01c368 the value for the s_mac key is copied using strcpy to the buffer at 0xa000170c. This buffer is 25 bytes large, sending anything longer will cause a buffer overflow. The destination can also be shifted by using an sn_speaker parameter between "0" and "3".

The bug was discovered 06/19/2018. The weakness was presented 08/02/2018 (Website). It is possible to read the advisory at talosintelligence.com.
