CVE-2025-60069

Executive Summary

CVE-2025-60069 is a critical PHP Local File Inclusion (LFI) vulnerability discovered in the ThemeMove MinimogWP WordPress theme, affecting all versions up to and including 3.9.6. The vulnerability stems from improper control of a filename used in a PHP include/require statement, allowing an unauthenticated attacker to include arbitrary local files from the server. This can lead to sensitive information disclosure, including configuration files, database credentials, and potentially source code. The CVSS score of 8.1 (High) reflects the ease of exploitation and the high confidentiality impact. As of this report, no official patch has been released, and no public proof-of-concept (PoC) code is available.

Supply Chain & Package Security

This vulnerability affects a WordPress theme distributed via ThemeMove’s own channels and potentially through third-party marketplaces. Since it is a PHP application component, there is no NPM, PyPI, Go, or Ruby package involved. However, users should verify the integrity of their theme files and ensure they are obtained from trusted sources. The lack of a patch increases the risk of supply chain attacks if the theme is bundled with other plugins or themes.

CVSS Breakdown & Threat Level

• Attack Vector (AV): Network (N) – Exploitable remotely.
• Attack Complexity (AC): Low (L) – No special conditions required.
• Privileges Required (PR): None (N) – No authentication needed.
• User Interaction (UI): None (N) – No user action required.
• Scope (S): Unchanged (U) – The vulnerable component and the affected resource are the same.
• Confidentiality (C): High (H) – Full file read capability.
• Integrity (I): None (N) – No file modification.
• Availability (A): None (N) – No denial of service.

Threat Level: High. The vulnerability is trivial to exploit and can lead to complete disclosure of sensitive server-side files.

Deep Dive & Mechanics

The vulnerability is a PHP Local File Inclusion (LFI) caused by insufficient sanitization of user-supplied input used in a PHP include() or require() statement. In the MinimogWP theme, a parameter (likely a GET or POST parameter) is passed directly to a file inclusion function without proper validation or path restriction. An attacker can manipulate this parameter to traverse directories (e.g., using ../) and include arbitrary files from the server.

Root Cause: The theme likely uses a construct similar to:

include($_GET['file'] . '.php');

or

require_once($some_path . $_REQUEST['template']);

without checking for path traversal sequences or restricting the base directory.

Exploitation Scenario: An attacker sends a crafted HTTP request to a vulnerable endpoint, such as:

GET /wp-content/themes/minimog/?file=../../../../etc/passwd

If the theme includes the file with a .php extension appended, the attacker might use a null byte injection (though PHP 5.3+ mitigates this) or a path truncation technique. More likely, the vulnerable parameter is used in a way that allows direct inclusion without extension, or the extension is not enforced.

Impact: Successful exploitation allows reading any file readable by the web server user, including:

• /etc/passwd (user enumeration)
• /etc/nginx/nginx.conf or Apache configs (server configuration)
• wp-config.php (database credentials, salts, keys)
• /proc/self/environ (environment variables)
• Source code of other PHP files (further vulnerability discovery)

Vulnerable vs. Patched Code

Since no patch is available, we can only hypothesize the vulnerable code pattern and the expected fix.

Vulnerable Code (Hypothetical):

// In a template loader function
$template = $_GET['template'];
include( get_template_directory() . '/templates/' . $template . '.php' );

This allows path traversal if $template is not sanitized.

Patched Code (Expected):

$allowed_templates = array('home', 'single', 'page', 'archive');
$template = $_GET['template'];
if (in_array($template, $allowed_templates)) {
    include( get_template_directory() . '/templates/' . $template . '.php' );
} else {
    // Default template or error
    include( get_template_directory() . '/templates/page.php' );
}

Or using realpath() to resolve the path and ensure it stays within the allowed directory.

Exploitation & Lab Setup

Red Team (Offensive)

Prerequisites:

• A WordPress installation with MinimogWP theme version <= 3.9.6.
• Knowledge of a vulnerable endpoint (e.g., a page that accepts a file or template parameter).

Exploitation Steps:

1. Identify the vulnerable parameter by fuzzing common parameters like file, template, page, include, load.
2. Send a request to read /etc/passwd:

   GET /?file=../../../../etc/passwd HTTP/1.1
   Host: target.com
   

3. If the theme appends .php, try:

   GET /?file=../../../../etc/passwd%00 HTTP/1.1
   

   (Null byte injection may work on older PHP versions.)
4. Alternatively, use path truncation with a long string of ../ to bypass extension appending (PHP < 5.3.4).
5. Read wp-config.php:

   GET /?file=../../../../wp-config
   

   (If no extension appended, the file will be included as PHP; to read source, use php://filter if allow_url_include is off, but LFI typically reads raw content.)

Note: No public exploit code is available; this is a theoretical approach.

Blue Team (Defensive)

Detection:

• Monitor web server logs for suspicious ../ sequences in GET/POST parameters.
• Look for requests to theme files with unexpected parameters.
• Use WAF rules to block path traversal patterns.

Hunting:

• Search for requests containing %2e%2e%2f (URL-encoded ../) or ..%252f (double encoding).
• Check for requests to /wp-content/themes/minimog/ with parameters like file, template, include.

Lab Setup:

• Install WordPress with MinimogWP theme in a sandboxed environment.
• Enable detailed logging in Apache/Nginx.
• Use a tool like Burp Suite or OWASP ZAP to fuzz parameters.

Indicators of Compromise (IOCs)

• File Paths: /etc/passwd, /etc/shadow, /wp-config.php, /proc/self/environ
• URL Patterns: ?file=, ?template=, ?include=, ?page= followed by ../ sequences
• HTTP Requests: GET requests with path traversal sequences in query strings
• Log Entries: 200 OK responses to requests containing ../ in parameters
• Server Response: Inclusion of sensitive file contents in the HTTP response body

Remediation & Mitigation

Immediate Actions:

1. Disable the MinimogWP theme until a patch is available. Switch to a default WordPress theme (e.g., Twenty Twenty-Four).
2. Implement a Web Application Firewall (WAF) rule to block path traversal patterns in query strings.
3. Restrict file permissions on sensitive files (e.g., wp-config.php should be readable only by the web server user, but LFI bypasses this).

Long-Term Fix:

• The vendor must release a patched version that sanitizes user input and uses a whitelist of allowed files.
• As a workaround, developers can modify the theme code to use basename() and realpath() to restrict file inclusion to a specific directory.

Monitoring:

• Enable detailed logging and alert on any path traversal attempts.
• Regularly review server logs for suspicious activity.
