The flaw impacts multiple Wireless AC Nighthawk, Wireless AX Nighthawk (WiFi 6), and Wireless AC router models.
Netgear did not disclose any information about which component was affected by this bug or its impact. It did say that it is a pre-authentication buffer overflow vulnerability.
The impact of a successful buffer overflow exploitation can range from crashes following denial of service to arbitrary code execution if code execution is achieved during the attack. Attackers can exploit this flaw in low-complexity attacks without requiring permissions or user interaction.
In its security advisory, Netgear "strongly recommends that you download the latest firmware as soon as possible."
