This exploit leverages an unauthenticated SQL injection (CVE-2018-6328) to achieve remote command execution as a low-privileged user, followed by a local privilege escalation (CVE-2018-6329) to execute arbitrary commands as root. It establishes a reverse shell via a bindshell and uploads a Python-based privilege escalation script.
