WPA2 KRACK Exploit: A SonicWall Alert

by Admin Admin

Exert from here:

On October 16, 2017 security researchers made public earlier findings in which they demonstrated fundamental design flaws in WPA2 that could theoretically lead to man-in-the-middle (MITM) attacks using key reinstallation attacks (KRACKs). Exploiting the vulnerability could enable cyber criminals to steal confidential information such as email, credit card numbers, passwords and more.

The WPA2 design flaws are protocol vulnerabilities and are not implementation specific. Both wireless access points and wireless clients are susceptible. Details of the vulnerabilities are available on the researchers’ website at

Impact to SonicWall customers

SonicWall Capture Labs has evaluated these vulnerabilities and determined that our SonicPoint and SonicWave wireless access points, as well as our TZ and SOHO Wireless firewalls, are not vulnerable to the flaws in WPA2.

SonicWall is working on a solution to provide an additional layer of protection for SonicWall customers that will block these man-in-the-middle attacks even from vulnerable unpatched clients. This will be delivered in a future SonicOS update.

Recommended Action

In order to minimize the potential impact of these vulnerabilities, SonicWall recommends customers take the following actions:
