Summary

ClearOS 7.9 contains an OS command injection vulnerability in the Log Viewer component that allows authenticated attackers to execute arbitrary commands by submitting unsanitized input through the filter parameter, which is interpolated directly into a shell command in File.php. Attackers can inject command substitution payloads into the filter parameter to execute arbitrary commands as the webconfig user, and due to extensive NOPASSWD sudo privileges granted to that user by default, immediately escalate to root.
