What is CVE-2017-8226?

The Amcrest IPM-721S device features a vulnerability where default hardcoded credentials are embedded in the firmware. These credentials are accessible through reverse engineering of the firmware, specifically version V2.420.AC00.16.R, using tools like binwalk. The vulnerable binary, 'sonia', utilizes a function that establishes these default values within the device's configuration files. Attackers can leverage this vulnerability to gain unauthorized access to the device, which may lead to further exploitation of the IoT environment.
