Netgear has fixed a high-severity vulnerability affecting multiple WiFi router models and advised customers to update their devices to the latest available firmware as soon as possible.
The flaw impacts multiple Wireless AC Nighthawk, Wireless AX Nighthawk (WiFi 6), and Wireless AC router models.
Although Netgear did not disclose any information about the component 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 a security advisory published on Wednesday, Netgear said it “strongly recommends that you download the latest firmware as soon as possible.”
