# Injection Analysis Report (SQLi & Command Injection)

## 1. Executive Summary

- **Analysis Status:** Complete  
- **Key Outcome:** **ZERO SQL injection and ZERO command injection vulnerabilities identified.** This application is a static Apache HTTP Server 2.4.49 instance with no application code, no database, and no dynamic content processing. No user input reaches SQL queries or shell command execution contexts.
- **Purpose of this Document:** This report documents the systematic analysis of all potential injection vectors and confirms that the application architecture fundamentally lacks the components necessary for injection vulnerabilities to exist.

## 2. Analysis Scope and Methodology

### Application Architecture Analysis

**Technology Stack:**
- **Web Server:** Apache HTTP Server 2.4.49 (static file server only)
- **Application Code:** None - serves only static HTML (45 bytes: "It works!")
- **Database:** None (no MySQL, PostgreSQL, MongoDB, SQLite, Redis)
- **Dynamic Processing:** None (all dynamic language modules disabled)

**User Input Processing:**
- Query parameters: IGNORED (not processed)
- POST data: IGNORED (not processed)
- Headers: LOGGED ONLY (not processed)
- Cookies: IGNORED (no session management)
- Path: Vulnerable to CVE-2021-41773 traversal but does not lead to injection sinks

### Injection Source Analysis

Following the reconnaissance deliverable (Section 9), I systematically analyzed all potential injection vectors:

#### SQL Injection Source Analysis

**Database Systems:** 
- ✗ No database system installed
- ✗ Database modules disabled in httpd.conf (lines 73, 81, 101)
- ✗ No database client binaries in container
- ✗ No ORM or query builder libraries
- ✗ No SQL keywords (SELECT, INSERT, UPDATE, DELETE) in codebase

**Evidence:**
- Container check: `which mysql psql sqlite3 mongo redis-cli` → Not found
- Application code files: 0 (only static HTML)
- SQL keyword search: 0 matches in application code
- Database configuration: All modules commented out (#LoadModule)

**Data Flow Analysis:**
```
HTTP Request → Apache 2.4.49 → Static File Handler → Static HTML Response
                                      ↓
                              No Database Layer
```

**Conclusion:** No mechanism exists for user input to reach SQL queries because no database exists and no application code processes user input.

#### Command Injection Source Analysis

**CGI Scripts:**
- `/usr/local/apache2/cgi-bin/printenv` - Permissions: 644 (NOT executable)
- `/usr/local/apache2/cgi-bin/test-cgi` - Permissions: 644 (NOT executable)
- `/usr/local/apache2/cgi-bin/printenv.vbs` - Windows-only (non-functional on Linux)
- `/usr/local/apache2/cgi-bin/printenv.wsf` - Windows-only (non-functional on Linux)

**Evidence:**
- All CGI scripts return HTTP 500: `(13)Permission denied: AH01241: exec failed`
- Scripts lack executable permissions (644 instead of 755)
- Scripts do NOT process user input (only print environment variables)

**Dynamic Language Modules:**
- ✗ mod_php DISABLED (no PHP execution)
- ✗ mod_python DISABLED (no Python execution)
- ✗ mod_perl DISABLED (no Perl execution)
- ✗ mod_ruby DISABLED (no Ruby execution)

**Server-Side Includes (SSI):**
- ✗ httpd.conf line 115: `#LoadModule include_module` (DISABLED)
- ✗ No `<!--#exec cmd="..."-->` processing possible

**Shell Execution Functions:**
- ✗ No application code exists to invoke shell commands
- ✗ No dynamic content handlers loaded

**Data Flow Analysis:**
```
HTTP Request → Apache 2.4.49 → Static File Handler → Static HTML Response
                                      ↓
                         No Command Execution Context
```

**Conclusion:** No mechanism exists for user input to reach shell command execution because:
1. No executable CGI scripts
2. No dynamic language modules loaded
3. No Server-Side Includes enabled
4. No application code invokes shell commands
5. Static HTML server only

## 3. Dominant Vulnerability Patterns

**Pattern:** N/A - No injection vulnerabilities identified

**Analysis Result:** The application architecture is fundamentally incompatible with injection vulnerabilities. It is a static file server with no:
- Database layer (SQL injection impossible)
- Command execution contexts (Command injection impossible)
- Dynamic content processing (Template injection impossible)
- User input processing (No data flow to sinks)

## 4. Strategic Intelligence for Exploitation

**Injection Exploitation Potential:** **NONE**

This application **cannot be exploited via SQL injection or command injection** because:
1. No SQL queries exist in the codebase
2. No shell commands are executed by the application
3. No user input is processed by application code
4. The server only serves static files

**Primary Vulnerability Class:** This application is vulnerable to **CVE-2021-41773 (Path Traversal)**, not injection attacks. The path traversal vulnerability allows arbitrary file read but does not enable SQL injection or command injection.

**Correct Exploitation Approach:**
- Use path traversal to read `/tmp/flag`
- Use path traversal to read `/proc/self/environ`
- Use path traversal to read system files (`/etc/passwd`)

**Out of Scope for Injection Analysis:**
- Path traversal exploitation (different vulnerability class)
- Information disclosure (no injection component)
- Configuration security issues (no injection component)

## 5. Vectors Analyzed and Confirmed Secure

Since no injection sinks exist, all input vectors are inherently secure from injection attacks by architectural design:

| **Source (Parameter/Key)** | **Endpoint/File Location**      | **Defense Mechanism Implemented**         | **Verdict** |
|-----------------------------|--------------------------------|-------------------------------------------|-------------|
| Query parameters            | All endpoints                  | Not processed by application (ignored)    | SAFE (No sink exists) |
| POST body data              | All endpoints                  | Not processed by application (ignored)    | SAFE (No sink exists) |
| HTTP headers                | All endpoints                  | Only logged, not processed                | SAFE (No sink exists) |
| Cookie values               | All endpoints                  | Not processed (no session management)     | SAFE (No sink exists) |
| File uploads                | All endpoints                  | Not processed (no upload handler)         | SAFE (No sink exists) |
| URL path                    | All endpoints                  | Vulnerable to traversal, but no injection sinks | SAFE (No SQL/CMD sinks) |

**Note:** These vectors are "safe" from injection specifically because no injection sinks exist. The URL path is vulnerable to **path traversal (CVE-2021-41773)**, which is a different vulnerability class outside the scope of injection analysis.

## 6. Analysis Constraints and Blind Spots

**No Blind Spots Identified:** The analysis is comprehensive because:
1. The entire codebase consists of only static HTML and configuration files
2. No application code exists to analyze
3. All potential injection vectors (CGI, SSI, dynamic modules) are disabled or non-functional
4. Container inspection confirmed no database or command execution capabilities

**Confidence Level:** **HIGH** - The absence of injection vulnerabilities is architecturally guaranteed by the lack of:
- Database systems
- Application code
- Dynamic content processing
- User input processing

**Limitations:**
- This analysis only covers SQL injection and command injection
- Path traversal vulnerabilities (CVE-2021-41773) are documented in reconnaissance but out of scope for this phase
- If the application were modified to add dynamic content processing or database connectivity, re-analysis would be required

## 7. Conclusion

**Final Verdict:** This Apache 2.4.49 static web server has **ZERO exploitable SQL injection or command injection vulnerabilities** due to its architectural design as a static file server with no application code, no database, and no dynamic content processing capabilities.

**Exploitation Queue Status:** Empty (0 vulnerabilities passed to exploitation phase)

**Recommendation:** Focus penetration testing efforts on the confirmed **CVE-2021-41773 path traversal vulnerability**, which is the primary security issue in this application.
