Description Preview

An exploitable firmware downgrade vulnerability exists in Insteon Hub running firmware version 1013. The firmware upgrade functionality, triggered via PubNub, retrieves signed firmware binaries using plain HTTP requests. The device doesn't check the firmware version that is going to be installed and thus allows for flashing older firmware images. To trigger this vulnerability, an attacker needs to impersonate the remote server 'cache.insteon.com' and serve any signed firmware image. This vulnerability has a high severity rating with a CVSS base score of 8.6.

Overview

The vulnerability lies in the firmware upgrade functionality of the Insteon Hub running firmware version 1013. The device does not verify the firmware version that is going to be installed, allowing an attacker to flash older firmware images. The attack can be triggered remotely over the network without any user interaction. The attack complexity is low and does not require any special privileges.

Remediation

Users are advised to update their Insteon Hub to the latest firmware version to mitigate this vulnerability. It is also recommended to use secure protocols such as HTTPS for firmware updates to prevent attackers from impersonating the remote server.
