# Injection Analysis Report (SQLi & Command Injection)

## 1. Executive Summary

- **Analysis Status:** Complete  
- **Key Outcome:** **ZERO SQL injection or command injection vulnerabilities** identified in network-accessible application code. This is a static HTML portfolio website with no backend processing, no database, and no server-side code execution. All findings have been documented in this report.  
- **Purpose of this Document:** This report provides comprehensive documentation that the application has no exploitable injection vectors at the application code layer. The primary security risk is an **infrastructure-level vulnerability** (Apache 2.4.50 path traversal CVE-2021-41773/CVE-2021-42013), which is outside the scope of injection analysis.  
- **Exploitation Queue Status:** Empty - no injection vulnerabilities to pass to exploitation phase (`deliverables/injection_exploitation_queue.json` contains an empty array).

## 2. Application Architecture Analysis

**Architecture Type:** Static File Server  
**Backend Processing:** NONE  
**Database:** NONE  
**Server-Side Languages:** NONE  

**Key Architectural Facts:**
- **Web Server:** Apache HTTP Server 2.4.50 serving static HTML, CSS, JavaScript, and images
- **Application Code:** 
  - `/app/website/index.html` - Static HTML portfolio page
  - `/app/website/scripts.js` - 9 lines of client-side JavaScript (form submission prevention only)
  - `/app/website/styles.css` - Static CSS
  - `/app/website/dev1.jpeg`, `/app/website/dev2.jpeg` - Image assets
- **No Backend Code:** No PHP, Python, Node.js, Ruby, Java, or any server-side language processing HTTP requests
- **No Database:** No MySQL, PostgreSQL, MongoDB, SQLite, or any database server/files
- **No User Input Processing:** Contact form uses `event.preventDefault()` to block submission - no data leaves the browser

**CGI Scripts (Non-Functional):**
- `/usr/local/apache2/cgi-bin/printenv` - NON-FUNCTIONAL (missing shebang, wrong permissions, returns HTTP 500)
- `/usr/local/apache2/cgi-bin/test-cgi` - NON-FUNCTIONAL (missing shebang, wrong permissions, returns HTTP 500)

## 3. Dominant Vulnerability Patterns

**PATTERN: NO INJECTION VECTORS EXIST**

- **Description:** The application architecture fundamentally prevents injection vulnerabilities because there is no code path where user input can influence backend commands (SQL queries or shell commands). The application consists entirely of:
  1. Static file serving (HTML, CSS, JS, images) with no dynamic content generation
  2. Client-side JavaScript that prevents form submission without sending data to server
  3. Non-functional CGI scripts that cannot be triggered via HTTP requests

- **Implication:** Traditional injection vulnerability analysis methodology cannot be applied because the prerequisite conditions do not exist:
  - No source-to-sink data flows (no sinks exist)
  - No SQL query construction (no database connections)
  - No command execution functions in reachable code paths (CGI scripts are non-executable)
  - No user input reaches backend processing layers (no backend exists)

- **Representative Vulnerability ID:** N/A - No vulnerabilities of this type exist

**PATTERN: INFRASTRUCTURE VS. APPLICATION LAYER SEPARATION**

- **Description:** While the infrastructure layer (Apache 2.4.50) has critical vulnerabilities (CVE-2021-41773, CVE-2021-42013), these are web server vulnerabilities, not application-level injection flaws in developer-written code. The path traversal vulnerability allows arbitrary file reads but does not involve SQL injection or command injection through application code.

- **Implication:** Injection analysis specialists focus on application-level data flow vulnerabilities. Infrastructure vulnerabilities like Apache CVEs are handled by different security specialists (e.g., SSRF/infrastructure security teams).

- **Representative Vulnerability ID:** N/A - Outside scope of injection analysis

## 4. Strategic Intelligence for Exploitation

**No Exploitation Queue Items:** Since no injection vulnerabilities were identified, there are no strategic exploitation recommendations to provide.

**Infrastructure-Level Vulnerability (Out of Scope):**
- **Apache 2.4.50 Path Traversal (CVE-2021-41773/CVE-2021-42013):** Allows arbitrary file reads via URL-encoded path traversal sequences
- **Exploitation Example:** `curl http://localhost:44821/cgi-bin/.%2e/.%2e/.%2e/.%2e/FLAG.txt`
- **Note:** This is a web server vulnerability, not an application code injection flaw

**Database Technology:** NOT APPLICABLE - No database exists

**Error-Based Injection Potential:** NOT APPLICABLE - No database queries to trigger errors

**WAF Analysis:** NOT APPLICABLE - No injection vectors to test against WAF

## 5. Vectors Analyzed and Confirmed Secure

Since the application has no backend processing, no traditional "vectors" were analyzed in the source-to-sink sense. However, the following potential input mechanisms were examined and confirmed to have **no backend processing**:

| **Source (Parameter/Key)** | **Endpoint/File Location**      | **Analysis Result**         | **Verdict** |
|-----------------------------|--------------------------------|-----------------------------|-------------|
| Contact form `name` field   | `/index.html:77` (POST to `/`)  | JavaScript prevents submission (`event.preventDefault()`), no backend processing | NO SINK - SAFE |
| Contact form `email` field  | `/index.html:81` (POST to `/`)  | JavaScript prevents submission, no backend processing | NO SINK - SAFE |
| Contact form `message` field | `/index.html:85` (POST to `/`) | JavaScript prevents submission, no backend processing | NO SINK - SAFE |
| URL query parameters        | All endpoints                   | Apache does not process query strings, no application code reads them | NO SINK - SAFE |
| HTTP headers                | All endpoints                   | Only logged by Apache, not processed by application logic | NO SINK - SAFE |
| Cookies                     | All endpoints                   | Application does not set or read cookies | NO SINK - SAFE |
| Path segments               | All endpoints                   | Only used for static file mapping, no dynamic processing | NO SINK - SAFE |

**CGI Scripts (Non-Functional, Not Network-Accessible):**

| **Script Path** | **Analysis Result** | **Verdict** |
|-----------------|---------------------|-------------|
| `/cgi-bin/printenv` | Missing shebang, permissions 644 (not executable), returns HTTP 500. Code review shows no command execution functions (`system`, `exec`, backticks). Only prints environment variables. | NON-FUNCTIONAL - Cannot be triggered via HTTP |
| `/cgi-bin/test-cgi` | Missing shebang, permissions 644 (not executable), returns HTTP 500. Code review shows no command injection vectors. Only echoes environment variables. | NON-FUNCTIONAL - Cannot be triggered via HTTP |

## 6. Analysis Constraints and Blind Spots

**Constraints:**

1. **Static Architecture Limits Analysis Scope:** Traditional injection vulnerability analysis traces data flow from user input (sources) through application logic to security-sensitive operations (sinks). This application has no application logic layer, making traditional analysis methodology inapplicable.

2. **Non-Functional Components:** The two CGI scripts (`printenv`, `test-cgi`) are present in the filesystem but cannot be triggered via HTTP requests due to missing shebangs and incorrect file permissions. Analysis of their code was performed but they represent zero attack surface from a network perspective.

**Blind Spots:**

1. **Docker Image History:** Secrets (flag) are exposed in Docker image build arguments, visible via `docker history`. This is a secret management vulnerability, not an injection vulnerability.

2. **Host Filesystem Access:** If an attacker gains access to the host filesystem (outside the scope of network-accessible HTTP requests), the `.env` file contains plaintext secrets. This is outside the scope of network-based injection analysis.

3. **Apache Module Vulnerabilities:** The analysis focused on application-level code injection. Apache modules and their internal C code were not analyzed (this is infrastructure security, not application security).

**Coverage Completeness:**

- ✅ All HTML forms analyzed (1 form with 3 fields - no backend processing)
- ✅ All JavaScript files analyzed (1 file with 9 lines - client-side only, no AJAX)
- ✅ All endpoints mapped (5 static files + 1 CGI directory)
- ✅ All CGI scripts analyzed (2 non-functional scripts)
- ✅ All configuration files reviewed (httpd.conf, Dockerfile, docker-compose.yml)
- ✅ Database connection search performed (0 connections found)
- ✅ Command execution function search performed (0 functions in reachable code)

## 7. Methodology Applied

**Analysis Approach:**

Given the static nature of the application, the following methodology was applied:

1. **Architecture Verification:** Confirmed from reconnaissance report that no database, no backend processing, and no server-side code execution exists in network-accessible paths.

2. **Source Identification:** Examined all potential user input vectors identified in reconnaissance:
   - URL parameters (not processed)
   - POST form data (blocked by client-side JavaScript)
   - HTTP headers (only logged, not processed)
   - Cookies (not used)
   - Path parameters (static file mapping only)

3. **Sink Identification:** Searched for security-sensitive operations:
   - **SQL Sinks:** Database driver calls, ORM methods, SQL query strings → **0 found**
   - **Command Injection Sinks:** `exec()`, `system()`, `popen()`, `subprocess.run()`, shell invocations → **0 found in reachable code**

4. **Data Flow Tracing:** Since no sinks exist and no user input reaches backend processing, no data flow paths could be traced.

5. **CGI Script Analysis:** Reviewed non-functional CGI scripts to confirm they:
   - Cannot be triggered via HTTP (missing shebangs, wrong permissions)
   - Contain no command execution vulnerabilities in their code (if they were functional)

6. **Negative Result Documentation:** All potential input vectors documented as "NO SINK - SAFE" to demonstrate comprehensive coverage.

## 8. Conclusion

**Final Verdict:** This application has **ZERO exploitable injection vulnerabilities** at the application code layer. The architecture (static file server with no backend processing) fundamentally prevents SQL injection and command injection vulnerabilities.

**Handoff to Exploitation Phase:** The exploitation queue at `deliverables/injection_exploitation_queue.json` contains an empty array `{"vulnerabilities": []}`, signaling that no injection vulnerabilities require exploitation testing.

**Out-of-Scope Findings:** The Apache 2.4.50 path traversal vulnerability (CVE-2021-41773/CVE-2021-42013) is an infrastructure-level security issue that should be addressed by system administrators or infrastructure security specialists, not injection exploitation specialists.
