Summary

An attacker could send an authenticated HTTP request to trigger this vulnerability in Insteon Hub running firmware version 1012. At 0x9d01bad0 the value for the host key is copied using strcpy to the buffer at 0xa00016e0. This buffer is 32 bytes large, sending anything longer will cause a buffer overflow.

Exploit prediction

1.36% chance of exploitation in the next 30 days, higher than 71% of all scored CVEs (FIRST EPSS, 2026-11-08).
