Générateur de règles WAF « produit absent » — Plan d'implémentation

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Générer, dans secubox-cve-triage, des règles WAF en mode detect qui fichent les scanners sondant des produits absents de la box — à partir d'un sous-ensemble Nuclei vendored, filtré par deux barrières de présence.

Architecture: Pipeline de fonctions pures (extraction Nuclei → candidat ; oracle de présence à deux barrières) plus un adaptateur d'inventaire mince (dpkg ∪ vhosts ∪ modules) et un émetteur additif/atomique qui écrit une seule catégorie product_absent_probes dans waf-rules.json. Sortie toujours en detect, jamais armée.

Tech Stack: Python 3.11, PyYAML (à ajouter aux deps), stdlib. Aucune autre dépendance.

Spec: docs/superpowers/specs/2026-07-18-waf-product-absent-generator-design.md

Global Constraints

• Zéro faux positif par construction. Un candidat n'est généré que s'il franchit les deux barrières : (1) famille d'appliance connue-absente ET (2) absent de dpkg ∪ vhosts routés ∪ modules.
• Dans le doute, PRÉSENT. Toute source de présence illisible/indéterminable ⟹ on ne génère rien (mieux vaut rater une sonde que bannir un vrai utilisateur).
• Sortie toujours en mode: "detect". Aucun chemin de code n'émet escalate ni block. La promotion en escalate est une décision humaine, hors de ce générateur.
• Additif et idempotent. Régénérer ne modifie QUE la catégorie product_absent_probes ; les 17 autres catégories de waf-rules.json sont préservées. Écriture atomique (temp + os.replace).
• Modules purs sans import de api.main. api/main.py lit la config à l'import (comme secubox-waf/users) ; les modules wafgen/* ne doivent PAS l'importer, pour rester testables sans board — même leçon que redact.py.
• Vendored, pas de réseau au runtime. Le service ne clone rien ; il lit le sous-ensemble embarqué. La curation est un script mainteneur hors-ligne.
• Python 3.11, PyYAML (python3-yaml, à ajouter à debian/control). SPDX 4-line header sur chaque .py. Commits terminés par Co-Authored-By: Gerald KERMA <devel@cybermind.fr>. Aucune référence à Claude.
• Tests par répertoire : .venv/bin/python -m pytest packages/secubox-cve-triage/tests -q. Jamais pytest common/ packages/ (collision api, cf. pytest.ini).

• Step 7 : packaging

Ajouter python3-yaml aux Depends de packages/secubox-cve-triage/debian/control (après python3). Vérifier la ligne Depends: existante et y insérer python3-yaml,.

Dans packages/secubox-cve-triage/debian/install, ajouter (adapter au style existant — lire d'abord) :

api/wafgen/*.py         usr/lib/secubox/cve-triage/api/wafgen/
sbin/secubox-cvectl     usr/sbin/
nuclei-subset/*         usr/lib/secubox/cve-triage/nuclei-subset/

• Step 8 : suite complète + vérif YAML réelle

.venv/bin/python -m pytest packages/secubox-cve-triage/tests -q

Attendu : 28 passed (8+7+4+6+3).

Vérifier que les deux templates vendored passent le pipeline réel :

cd /home/reepost/CyberMindStudio/secubox-deb/secubox-deb/packages/secubox-cve-triage
.venv/bin/python -c "
import sys; sys.path.insert(0,'.')
from pathlib import Path
from api.wafgen.generate import generate
kept, rej = generate(Path('nuclei-subset'), present=set(), present_complete=True)
print('retenus:', [c.cve for c in kept])
print('rejets :', rej)
assert len(kept) == 2, kept
print('les 2 templates vendored produisent bien un candidat ✓')
"

Attendu : les 2 CVE retenus.

• Step 9 : commit

git add packages/secubox-cve-triage/
git commit -m "feat(cve-triage): secubox-cvectl waf-rules generate + vendored Nuclei subset

CLI (dry-run by default, --apply to write) orchestrates extract + presence +
emit. Ships a small vendored Nuclei subset (MIT, with LICENSE) of appliance/KEV/
URL-extractable templates + an offline maintainer curation script. Adds
python3-yaml to Depends. --apply refuses to write when the presence inventory is
incomplete (fail-safe).

Task 6 : Panel — onglet règles générées

Files:

• Modify: packages/secubox-cve-triage/api/main.py (ajouter les routes GET /waf-rules + POST /waf-rules/generate)
• Modify: packages/secubox-cve-triage/www/cve-triage/index.html (onglet)

Interfaces:

• Consumes: generate, gather_present, write_category (wafgen) ; require_jwt (secubox_core).

• Produces: routes /waf-rules (aperçu : retenus + rejets, dry-run) et /waf-rules/generate (POST --apply).

• Step 1 : implémenter les routes

Dans packages/secubox-cve-triage/api/main.py, à côté des routes existantes (après les @router.get(...) du domaine feeds), ajouter :

@router.get("/waf-rules", dependencies=[Depends(require_jwt)])
async def waf_rules_preview():
    """Dry-run: what would be generated (kept + rejections), writes nothing."""
    from .wafgen.generate import generate
    from .wafgen.inventory import gather_present
    from pathlib import Path
    present, complete = gather_present()
    kept, rejected = generate(Path("/usr/lib/secubox/cve-triage/nuclei-subset"),
                              present, complete)
    return {
        "present_count": len(present), "inventory_complete": complete,
        "kept": [{"cve": c.cve, "vendor": c.vendor, "product": c.product,
                  "path": c.path} for c in kept],
        "rejected": [{"file": n, "reason": r} for n, r in rejected],
    }


@router.post("/waf-rules/generate", dependencies=[Depends(require_jwt)])
async def waf_rules_generate():
    """Apply: write product_absent_probes (detect mode). Refuses if inventory
    is incomplete (fail-safe)."""
    from .wafgen.generate import generate
    from .wafgen.inventory import gather_present
    from .wafgen.emit import write_category
    from datetime import datetime, timezone
    from pathlib import Path
    present, complete = gather_present()
    if not complete:
        raise HTTPException(409, "presence inventory incomplete — refusing (fail-safe)")
    kept, rejected = generate(Path("/usr/lib/secubox/cve-triage/nuclei-subset"),
                              present, complete)
    now = datetime.now(timezone.utc).strftime("%Y-%m-%dT%H:%M:%SZ")
    write_category(Path("/etc/secubox/waf/waf-rules.json"), kept, now=now)
    return {"success": True, "written": len(kept), "mode": "detect",
            "rejected": len(rejected)}

Note à l'implémenteur : require_jwt, HTTPException, router/app sont déjà importés dans main.py — vérifier leurs noms exacts et réutiliser. Ne pas ré-importer différemment.

• Step 2 : l'onglet webui

Dans packages/secubox-cve-triage/www/cve-triage/index.html, ajouter un onglet « WAF probes » qui appelle GET /api/v1/cve-triage/waf-rules, affiche kept (cve/vendor/path) et rejected (file/reason), plus un bouton « Generate » qui POST /waf-rules/generate puis rafraîchit. Suivre le style cyan hybrid-skin déjà présent dans le fichier (réutiliser ses classes .card/.btn/.tab ; lire l'existant). esc() sur toute valeur d'API ; lire le token depuis localStorage.getItem('sbx_token') ; 401 → toast.

node --check le JS extrait.

• Step 3 : vérifier que le module se charge encore

cd /home/reepost/CyberMindStudio/secubox-deb/secubox-deb/packages/secubox-cve-triage
python3 -c "import ast; ast.parse(open('api/main.py').read()); print('main.py parse ✓')"

(La suite tests/ reste verte — les routes ajoutées n'importent wafgen que dans le corps des handlers, pas au niveau module, donc elles n'introduisent pas de lecture de config supplémentaire.)

• Step 4 : commit

git add packages/secubox-cve-triage/api/main.py packages/secubox-cve-triage/www/cve-triage/index.html
git commit -m "feat(cve-triage): panel tab for generated WAF probes (dry-run + apply)

GET /waf-rules previews kept + rejections (writes nothing); POST /waf-rules/
generate applies (detect mode), refusing on an incomplete presence inventory.
Cyan hybrid-skin tab, esc()'d, sbx_token auth.

Auto-revue du plan

Couverture du spec :

Exigence du spec	Tâche
Source vendored Nuclei (MIT, pas de git-pull runtime)	5 (subset + LICENSE + curation script)
Extraction : sonde URL, rejets journalisés	1
Barrière 1 : allowlist appliance	2
Barrière 2 : union dpkg ∪ vhosts ∪ modules	3
Fail-safe « dans le doute présent »	2 (present_complete), 3 (complete), 5 (CLI refuse), 6 (409)
Trou LXC/vhost (nextcloud absent dpkg mais routé)	3 (source vhosts + test)
Sortie catégorie detect, additive, idempotente, atomique	4
Jamais escalate/block (jamais armé)	4 (test + mutation)
CLI dry-run par défaut	5
Panel onglet	6
Tests capables d'échouer (mutation)	1,2,3,4

Hors périmètre, donc absent (voulu) : git-pull runtime, promotion auto detect→escalate, génération hors appliance, généralisation des patterns, corrélation ASN/JA4.

Placeholders : aucun — chaque étape porte son code et sa commande. Les « notes à l'implémenteur » (routes de main.py, style du panel) demandent de lire l'existant plutôt que d'inventer — instruction, pas trou.

Cohérence des types : Candidate (Task 1) consommé par 2/4/5 ; should_generate(candidate, present, present_complete) (Task 2) appelé identiquement en 5 ; gather_present() -> (set, bool) (Task 3) consommé en 5/6 ; write_category(rules_path, candidates, *, now) / CATEGORY_KEY (Task 4) consommés en 5/6 ; generate(subset_dir, present, present_complete) -> (kept, rejected) (Task 5) consommé en 6. Noms stables partout.
