On July 19th, 2019, SonicWall disclosed a newly discovered critical vulnerability in a number of their physical firewall appliances. ADNET strongly advises that companies take steps to apply an update patch as soon as possible. ADNET’s Security Team has been monitoring this situation through various security threat sources to ensure that we are acting upon the most current information.

What does this vulnerability do?

The vulnerability affects only the management interface of devices which are used to log in to and interact with its settings and configuration. To exploit this weakness, an attacker would need access to the management interface. The security technology and functionality of the devices with this vulnerability, including prevention and detection capabilities, are not directly affected or impacted.

Am I at risk?

If your SonicWall firewall is configured to allow access to the management interface from the internet, your exposure and risk is high. If access to the management interface is configured to allow access only from trusted networks and sources, the severity and potential risk is significantly reduced. ADNET strongly advises applying the security patch immediately to eliminate the risk as soon as possible.
