NETGEAR D3600 and D6000 modem routers have a hardcoded password vulnerability in firmware versions before 1.0.0.76, allowing attackers to gain full control.
Vulnerability
The hardcoded password vulnerability affects NETGEAR D3600 and D6000 modem routers running firmware versions prior to 1.0.0.76 [1]. The vulnerability is due to a hardcoded credential embedded in the firmware that can be used to authenticate to the device.
Exploitation

Impact
Successful exploitation allows an attacker to gain full control over the device, potentially leading to disclosure of sensitive information, modification of device settings, or denial of service. The CVSS score is 8.8 (High), with significant impact on confidentiality, integrity, and availability [1].
Mitigation
NETGEAR has released firmware version 1.0.0.76 for both D3600 and D6000 to fix this issue [1]. Users are strongly recommended to download and install the latest firmware from NETGEAR Support as soon as possible. No workaround other than upgrading is mentioned.
