Description
The vulnerability allows a remote attacker to gain full control to the device.
The weakness exists due to use of hardcoded root SSH credentials to be stored within the “core_app” binary utilised by the EE router for networking services. A remote attacker with knowledge of the default password (“REDACTED”) and able to communicate with the SSH server can log into the “admin” user over SSH, discover the hard-coded SSH password using strings on the web server binary, bypass of the “AP Isolation” mode that is supported by the router, as well as the settings for multiple Wireless networks, and compromise the router.
Remediation
Cybersecurity Help is currently unaware of any solutions addressing the vulnerability.
