Borrowed Crown
Easy remote foothold via `GET /api/ping?host=` command injection on `:8080`, but `/flag` is root-only so winning requires privilege escalation. A constrained sudoers rule is intentionally exploitable: `ctf ALL=(root) NOPASSWD: /usr/bin/find /var/log/webapp -type f -name *.log *` (wildcard abuse, GTFOBins-style). Uptime is enforced via `GET /api/health` (15s checks, 30s grace, 3 fails = elimination). Expect quick shells, then privesc races while keeping the service alive.
