Identifying a WordPress Site
If you’re using Metasploit to perform a penetration test and want to target a WordPress site, it’s essential to identify if the target is running WordPress or not. Here are some methods to help you determine if the target is a WordPress site.
Checking the IP Address
Before performing any tests, you can check the IP address of the target site. If the IP address is associated with WordPress, it’s likely that the target site is running WordPress. You can use a tool like whois to retrieve the IP address information and check if it’s associated with WordPress.
Analyzing the URI
Another way to identify a WordPress site is to analyze the URI. WordPress sites typically have a specific URI structure, which includes /wp-admin/, /wp-content/, and /wp-includes/. You can check if these URIs exist on the target site by performing an HTTP request using a tool like curl.
TargetURI
Metasploit uses the TARGETURI variable to determine the base path to the WordPress application. If the TARGETURI is set to the root directory of the target site, Metasploit will not be able to detect WordPress using the various fingerprinting techniques. Therefore, it’s essential to set the TARGETURI correctly to detect WordPress.
HTTP Requests
HTTP requests can provide valuable information about the target site. You can use tools like nmap or curl to retrieve HTTP headers and analyze them for WordPress-specific information. For example, WordPress sites typically include the X-Powered-By header, which indicates that the site is running on WordPress.
SSL
If the target site is using SSL, you can analyze the SSL certificate to determine if it’s associated with WordPress. WordPress sites typically use SSL certificates issued by Let’s Encrypt, which can provide a clue that the target site is running WordPress.
In summary, identifying a WordPress site is crucial before attempting any exploits or brute-force attacks. By analyzing the IP address, URI, HTTP requests, and SSL certificate, you can determine if the target site is running WordPress and take appropriate actions.
Metasploit and WordPress

Another module that can be used to exploit WordPress is the exploit/unix/webapp/wp_admin_shell_upload module. This module allows penetration testers to upload a PHP shell to the WordPress site’s wp-content/plugins directory, which can then be used to execute arbitrary code on the remote host.
When using Metasploit to exploit WordPress, it is essential to specify the correct target host and port. The rhost and rport options can be used to specify the remote host and port, respectively. It is also important to ensure that the correct module is selected and that the source code is up-to-date.
In conclusion, Metasploit is a powerful tool that can be used to exploit vulnerabilities in WordPress sites. There are several modules available that can be used for enumeration, brute-forcing, and remote code execution. When using Metasploit, it is important to specify the correct target host and port, select the correct module, and ensure that the source code is up-to-date.
Common Vulnerabilities in WordPress Sites
WordPress is a popular content management system used by millions of websites worldwide. However, like any software, it has its vulnerabilities that can be exploited by attackers. Here are some of the most common vulnerabilities found in WordPress sites:
Remote Code Execution (RCE)
Remote Code Execution (RCE) is a vulnerability that allows an attacker to execute arbitrary code on a remote system. In WordPress, RCE can occur due to outdated plugins and themes, which can allow attackers to inject malicious code into the site. To prevent RCE, it is important to keep WordPress, plugins, and themes updated to the latest version.
User Enumeration
User Enumeration is a vulnerability that allows an attacker to identify valid usernames on a WordPress site. This can be done through various methods, such as using the XML-RPC interface or by analyzing the HTTP response codes. To prevent user enumeration, it is important to disable the XML-RPC interface and configure the site to return the same HTTP response codes for valid and invalid usernames.
