Summary

The SonicWall Secure Remote Access server (specifically version 8.1.0.2-14sv) features remote command injection vulnerabilities within its web administrative interface. These vulnerabilities are linked to the diagnostics CGI component, which handles system status emails. Specifically, the parameters 'tsrDeleteRestartedFile' and 'currentTSREmailTo' are inadequately sanitized before invoking system calls, creating an avenue for attackers to execute arbitrary commands. Successful exploitation can grant an attacker shell access on the affected system, running under the context of the nobody user account.
