What is CVE-2016-9683?

The SonicWall Secure Remote Access server is susceptible to a Remote Command Injection vulnerability through its web administration interface. This flaw lies within the 'extensionsettings' CGI component, which inadequately sanitizes input from a certain multi-part form submission related to server configurations. The vulnerability allows an attacker to pass harmful commands via the 'scriptname' variable, leading to unauthorized shell access to the affected server under the 'nobody' user account. Prompt action is needed to mitigate risks associated with this security issue.
