SonicWall Critical Vulnerability

What Was the Issue with the SMA 100 Series?

The issue that was reported was in relation to the SMA 100 series and was classified under CVE-2021-20034 under the CVE range. If the exploitation did occur, it would allow a hacker to delete files randomly from your system.

A SonicWall critical vulnerability is very usually, but our team is here to help clients act quickly and avoid issues in the future.

What Caused the SonicWall Vulnerability?

As a result of this, hackers can undertake malicious actions, such as deleting random files from your appliances without needing any type of authentication. They can bypass path traversal checks and even factory reset your SonicWall. This would allow them to have full admin access to your host, which could cause a huge range of issues for you. The Common Vulnerabilities and Exposures database rated this vulnerability a 9.1 out of 10. While there have been no reports of exploitation just yet, the sooner you take action, the more protected you will be.
