CIS490/exploits
max a88ac83db0 Close out the deployment-readiness gaps
Wraps the gaps surfaced in the "what is not implemented" audit so the
fleet really is shippable end-to-end. Verified live on the Pi:
  - cis490-shipper --ping → HTTP 200 through Caddy + mTLS via the
    new wg-pki client CA leaf
  - real episode dir → tar+zstd → PUT → HTTP 201 stored
  - re-ship same bytes → 200 (idempotent)
  - re-ship different bytes under same id → 409 (conflict)

Changes:

orchestrator/episode.py
  - EpisodeConfig.revert_at_start / revert_at_end (Tier 0+ snapshot/
    revert per docs/architecture.md). When set + qmp_socket present,
    EpisodeRunner issues loadvm <snapshot_name> and emits
    snapshot_revert / snapshot_revert_failed events on the same
    monotonic clock as everything else.

collectors/qmp.py
  - savevm() / loadvm() helpers using human-monitor-command, plus a
    test against the fake QMP server.

exploits/workloads.py
  - chunked_real_binary_upload() returns a ChunkedUpload plan: 8 KiB
    base64 chunks (~6 KiB binary each) so msfrpc never sees a buffer-
    busting payload. Includes a finalize step that sha256-verifies on
    the guest before exec.
  - real_binary_workload() now wraps the chunked plan for backwards
    compat with single-shot callers.

exploits/driver.py
  - Tier-4 dispatch walks the chunked plan in MSFExploitDriver:
    each chunk is a separate session_shell_write; finalize verifies;
    exec only runs on sha-ok. New events: real_binary_upload_begin,
    real_binary_verify, real_binary_aborted.

etc/cis490-orchestrator.service
  - Reads /etc/cis490/lab-host.env (FLEET_HOST_ID + optional BRIDGE).
  - Grants AmbientCapabilities CAP_NET_RAW (tcpdump for source 4) +
    CAP_SYS_ADMIN + CAP_PERFMON (perf for source 3) so collectors
    work under hardening.

scripts/install-lab-host.sh
  - Writes /etc/cis490/lab-host.env on first install with FLEET_HOST_ID
    defaulting to `hostname -s`.
  - Best-effort: fetches the Alpine baseline qcow2 (sha512-pinned) and
    builds cidata.iso with the in-guest agent embedded; symlinks both
    into /opt/cis490/vm/images/ so launchers find them.

scripts/fetch-alpine-baseline.sh
  - Idempotent fetcher for the Alpine 3.21 cloud-init nocloud qcow2
    matching the sha512 in docs/sources.md.

tools/plot_envelope.py
  - Rebuilt to render whatever telemetry the episode dir contains:
    proc → QMP block ops → perf IPC/miss-rate → bridge pkts/SYNs →
    guest agent load/mem. Missing sources are silently skipped.

tools/index_reader.py
  - cis490-index CLI: filter receiver's index.jsonl by host / sample
    / time range, sort, count-by group. Closest thing to a query
    interface until we stand up Postgres/Timescale.

samples/README.md
  - Rewritten to match the new manifest schema, the kind=real vs mimic
    split, the per-(host, slot, ep) selection mechanic, and the
    chunked-upload safety story.

Tests: 106 pass (was 102). New cases:
  - test_qmp.py — savevm + loadvm (HMP wrapper + error path)
  - test_tier4.py — chunked plan splitting, sha-pinned finalize,
    end-to-end driver walks all chunks + verify + exec via the fake
    msfrpc client

Closes the "what is not implemented" punch list.

exploits/

The Tier-3 exploit driver — fires a Metasploit module against a vulnerable target VM, watches for the resulting session, and stamps the session-open transition into the episode's events.jsonl so the labeler can mark armed → infecting honestly.

Layout

exploits/
  msfrpc.py           tiny msgpack-over-HTTPS client for msfrpcd
  driver.py           MSFExploitDriver — plugged in as EpisodeRunner.on_phase
  modules.py          ModuleConfig + TOML loader
  modules/
    vsftpd_234_backdoor.toml   first canned module (Metasploitable2)
    ...

Module configs

Each modules/*.toml describes one Metasploit module — its path, the options to set, and the payload to use. The driver reads these files to drive module.execute over msfrpc.

description = "..."
[module]
type = "exploit"                      # exploit | auxiliary | post
path = "unix/ftp/vsftpd_234_backdoor"

[module.options]
RHOSTS = "{{ target_ip }}"            # placeholder substituted at runtime
RPORT = 21

[payload]
path = "cmd/unix/interact"
[payload.options]                     # optional
# LHOST = "{{ target_ip }}"

[session]
type = "shell"

The only placeholder supported today is {{ target_ip }}. Add more in exploits/modules.py::ModuleConfig.render_options when needed.

Running

# 1. Start msfrpcd locally:
msfrpcd -P <password> -U msf -a 127.0.0.1 -p 55553

# 2. Drop a vulnerable target image at vm/images/<name>.qcow2 (e.g.
#    Metasploitable2 — see docs/sources.md for sha256).

# 3. Drive an episode:
MSFRPC_PASSWORD=<password> uv run python tools/run_tier3_demo.py \
    --module vsftpd_234_backdoor \
    --target-port 21 \
    --data-root data

The episode's events.jsonl will contain:

driver_setup        — module + target snapshotted before fire
exploit_fire        — module.execute issued
session_open        — new session id observed in session.list
session_landing_probe — first command response (id) recorded
sample_executed     — workload kicked off inside the session
session_dormant     — workload killed
session_killed      — session.stop at episode end

These pair with the standard phase labels in labels.jsonl so a downstream loader can reconcile "what the orchestrator scheduled" against "what actually happened on the wire".

Adding a module

  1. Drop a TOML at exploits/modules/<name>.toml per the schema above.
  2. Pick a payload that works without a callback channel until the br-malware bridge is in (see vm/launch_target.sh — SLIRP + restrict=on blocks reverse-tcp by design). cmd/unix/interact and other "session on the same socket" payloads are safe.
  3. Drive a quick check: uv run python tools/run_tier3_demo.py --module <name>.
  4. The new module is automatically picked up by tools/run_tier3_demo.py via --module <name>; no driver code changes needed.

We do not author exploits or modify upstream Metasploit code. The driver is a pure adapter from the project's phase machine to msfrpc.
