A vulnerability classified as critical has been found in SonicWALL Secure Remote Access Server up to 8.1.0.2-14sv (Remote Access Software). Affected is an unknown functionality of the file /cgi-bin/diagnostics. The manipulation of the argument tsrDeleteRestartedFile/currentTSREmailTo with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77.

This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The SonicWall Secure Remote Access server (version 8.1.0.2-14sv) is vulnerable to two Remote Command Injection vulnerabilities in its web administrative interface. These vulnerabilities occur in the diagnostics CGI (/cgi-bin/diagnostics) component responsible for emailing out information about the state of the system. The application doesn't properly escape the information passed in the 'tsrDeleteRestartedFile' or 'currentTSREmailTo' variables before making a call to system(), allowing for remote command injection. Exploitation of this vulnerability yields shell access to the remote machine under the nobody user account.
