Arlo Basestation firmware 1.12.0.1_27940 and prior firmware contain a networking misconfiguration that allows access to restricted network interfaces. This could allow an attacker to upload or download arbitrary files and possibly execute malicious code on the device.

Arlo Basestation firmware 1.12.0.1_27940 and prior contain a hardcoded username and password combination that allows root access to the device when an onboard serial interface is connected to.

This vulnerability allows attackers with physical access to escalate privileges on affected installations of Arlo Q Plus 1.9.0.3_278. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SSH service. The device can be booted into a special operation mode where hard-coded credentials are accepted for SSH authentication. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-12890.
