Adversarial audit of the auth surface confirmed several exploitable gaps. Every fix
auto-expires and never permanently locks the control plane (bare-IP recovery host and
the clusev:reset-admin CLI stay open).
Login:
- per-IP (20/min) + per-account (30/15min) buckets on top of the existing email+IP 5/min,
so a distributed multi-IP brute-force of the single admin account is capped instead of
scaling linearly with IPs. ip/acct counters decay on their own (a valid login doesn't
reset a flood's budget).
- constant-time: the unknown-email branch now runs one bcrypt against a fixed DUMMY_HASH
(evaluated before the `! $user ||` short-circuit), closing the account-enumeration
timing oracle.
2FA:
- TOTP replay protection — verifyTotp uses verifyKeyNewer with a persisted last-used step
(two_factor_last_used_step migration), so each 30s code is single-use. Passes 0 (never
null) as the old step, since null makes verifyKeyNewer return bare `true` not the step.
- challenge + 2FA-proof reset gain an IP-independent per-account backstop, capping the
distributed TOTP/backup brute-force surface.
Defense-in-depth / DoS:
- global throttle on /livewire/update (180/min per user-id-or-IP) via setUpdateRoute,
keeping 'web' + the persistent EnsureSecurityOnboarded gate intact.
- reauth throttle (5/min per user) on password change/profile; SMTP test-send capped
(3/10min per user) so the panel can't relay spam.
- SshClient gets a short, separate connect timeout (~5s) so a dead/tarpit host can't hold
a worker across several sequential 15s reads (the observed 8.3s /livewire/update DoS).
- profile password policy raised to 12 chars + mixed case + numbers (was 10).
Tests: BruteForceHardeningTest covers TOTP replay, per-email + per-IP login caps,
identical unknown/known rejection, and reauth throttling. Full suite 187 green; Codex
clean; verified in a real browser (login/polls/Livewire updates unaffected by the throttle).

Security pivot — make server hardening, SSH access, firewall, dashboard domain/TLS
and the release channel controllable from the dashboard (no SSH needed), with guards
so a remote change can never lock the operator out.
Foundation
- ssh_credentials gains name + disabled_at + last_used_at; CredentialVault refuses a
disabled credential. New key/value Setting model. FleetService::runPrivileged() /
runPlain() — central sudo-aware exec (base64-wrapped sh -c), live-verified as root.
A · control-plane self-hardening
- SecurityHeaders middleware: env-aware CSP (allows the Vite dev origin in dev, strict
same-origin in prod), X-Frame-Options DENY, nosniff, Referrer/Permissions-Policy,
HSTS when secure. 2FA brute-force throttle (5/60s). install.sh sets
SESSION_SAME_SITE=strict + EXPIRE_ON_CLOSE + SECURE_COOKIE (only behind TLS).
B · SSH credential management
- name/label on the access; a credential card on the server page with Bearbeiten /
Sperren-Entsperren (kill-switch) / Löschen (R5), all audited.
C · server hardening from the dashboard (guards + confirmation)
- HardeningService (PermitRootLogin no, PasswordAuthentication no, fail2ban,
unattended-upgrades) + FirewallService (UFW). HardeningAction modal previews the
exact root commands before applying. GUARDS: refuse to disable password-login when
Clusev itself logs in by password or no key exists; UFW opens the real sshd port +
80/443 before enabling. Live-verified non-destructively (previews, the password
guard refusing, ufw status read).
D+E · System page (/system)
- Dashboard Domain + Let's-Encrypt email (Setting) -> DeploymentService renders the
matching Caddy site block (honest: stages the file + shows the reload command, never
fakes TLS). Release channel (stable|beta|dev) configurable; Versions reads it.
Built largely by 4 parallel agents into disjoint files; shared files integrated + the
security-critical bits hardened by hand (the password-auth lock-out guard + env-aware CSP).
Verified (R12): /system + server detail + all 8 routes 200 / 0 console errors (CSP does
not break Livewire/Alpine/Vite); credential card + 5 hardening "Anwenden" buttons render;
the hardening modal opens with the command preview; System persists domain/channel +
renders valid Caddy config; runPrivileged runs as root + the vault refuses disabled creds.

Full feedback round — all browser-verified (R12: 7 routes 200, zero console errors)
and functionally tested live against the target host.
- Metrics are real AND honest: poller now stores cpu/mem/DISK/LOAD history (all
four sparklines real, not synthetic); KPIs show absolute context (Memory
"1,9 / 7,8 GB", Disk "13 / 80 GB", Load "4 Kerne"); tiles are status-coloured
and Load is rated against core count (so "yellow" actually means load≈0.7-1.0×
cores), not a fixed warning tint.
- File manager is functional: Hochladen (Livewire upload -> SFTP put), Download
(SFTP get -> streamed), and view/edit (new FileEditor modal: SFTP get, binary/
size guards, SFTP put on save + audit). File names + Bearbeiten open the editor.
- Settings redesigned (/frontend-design): account identity header + section nav
(Profil / Sicherheit) instead of flat stacked panels.
- Routes are English (R13): /einstellungen -> /settings; rule added to rules.md +
CLAUDE.md. Dummy data removed: the topbar "Flotte online / Uptime 42d" + dead
bell button are gone, replaced by a real "<online>/<total> online" pill.
New: app/Livewire/Modals/FileEditor + view; FleetService get/read/write/upload +
Sftp putFromFile/size.

Resolve all 12 confirmed findings from the SSH-integration review.
Security:
- TOFU host-key pinning (new VerifiesHostKey trait + servers.ssh_host_key column):
SshClient/Sftp record the server host key on first connect and refuse the
connection on any later mismatch — phpseclib does not pin host keys itself.
- PollMetrics keeps one long-lived SSH connection per server and reuses it across
ticks (a single login, not one per interval) — avoids fail2ban/auth-log churn;
dead connections are dropped and re-established next tick.
- @js() escaping for every server-controlled value interpolated into wire:click
(file names, paths, service names, SSH-key comments/fingerprints) — prevents
JS-string breakage / injection from untrusted remote data.
Correctness:
- parseKeys regex makes the key comment optional (keys without a comment were
silently dropped).
- parseVolumes pops the three trailing single-token df fields and rejoins the
rest, so mount points containing spaces parse correctly.
- Sftp gains a disconnect() method to match SshClient (explicit cleanup).
Rules:
- Services "Start" -> "Starten" (R9, German).
- Files breadcrumb buttons get min-w-11 + padding (R7, >=44px touch target).
Verified live: host key stored + mismatch refused + correct key reconnects;
poller reuse polls ok; all pages still render real data.
