CVE-2025-69081

Executive Summary

CVE-2025-69081 is a critical PHP Local File Inclusion (LFI) vulnerability discovered in the ThemeREX Hope WordPress theme (slug: charity-is-hope). The vulnerability stems from improper control of a filename used in a PHP include or require statement, allowing an unauthenticated attacker to include arbitrary local files from the server. This can lead to sensitive information disclosure, such as reading the wp-config.php file to obtain database credentials, or potentially achieving remote code execution if combined with file upload capabilities.

The vulnerability affects all versions of the Hope theme up to and including version 3.0.0. As of this report, no official patch has been released by the vendor (ThemeREX), and no public proof-of-concept (PoC) exploit code is available. The EPSS score is 0.0%, indicating low exploitation activity in the wild, but the technical severity remains high due to the potential impact.

Supply Chain & Package Security

This vulnerability is part of the WordPress ecosystem and is distributed via the WordPress theme repository or third-party marketplaces. Users who have installed the Hope theme are at risk. Since the theme is a commercial product, updates may be delivered through a custom update mechanism or manual download. The lack of a patch increases the risk for all installations.

CVSS Breakdown & Threat Level

• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
• Base Score: 8.1 (High)
• Attack Vector: Network (AV:N) – The vulnerability can be exploited remotely.
• Attack Complexity: Low (AC:L) – No special conditions are required.
• Privileges Required: None (PR:N) – No authentication needed.
• User Interaction: None (UI:N) – No user action is required.
• Scope: Unchanged (S:U) – The vulnerable component and the impacted component are the same.
• Confidentiality Impact: High (C:H) – Sensitive files can be read.
• Integrity Impact: None (I:N) – File contents cannot be modified.
• Availability Impact: None (A:N) – No denial of service.

Threat Level: High. The vulnerability allows unauthenticated file disclosure, which can lead to full site compromise if credentials are leaked.

Deep Dive & Mechanics

The vulnerability exists in the ThemeREX Hope theme's PHP code, likely in a file that handles template loading or shortcode rendering. The theme improperly sanitizes a user-supplied filename parameter before passing it to a PHP include() or require() function. This allows an attacker to traverse directories using ../ sequences and include arbitrary files from the server.

Root Cause: The theme likely uses a parameter like file, template, or page in a URL or POST request to dynamically include a PHP file. Without proper validation, an attacker can supply a path like ../../../../etc/passwd to read system files, or ../../../wp-config.php to read WordPress configuration.

Attack Vector: The attacker sends a crafted HTTP request to the WordPress site, targeting a vulnerable endpoint exposed by the theme. The request includes a path traversal payload in the filename parameter.

Impact: Successful exploitation allows reading of any file on the server that the web server user has access to. This includes:

• wp-config.php (database credentials, salts)
• /etc/passwd (user enumeration)
• Log files (may contain admin session tokens)
• PHP source code (to find further vulnerabilities)

Vulnerable vs. Patched Code

Since no patch is available, the vulnerable code is presumed to be present in all versions <= 3.0.0. A typical vulnerable pattern in WordPress themes is:

Vulnerable Code (example):

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

Patched Code (hypothetical):

<?php
$file = basename( $_GET['file'] );
$allowed_files = array( 'header', 'footer', 'sidebar' );
if ( in_array( $file, $allowed_files ) ) {
    include( get_template_directory() . '/' . $file . '.php' );
} else {
    // Handle error
}
?>

The patched version would use basename() to strip directory traversal, and implement a whitelist of allowed files.

Exploitation & Lab Setup

Red Team (Offensive)

Prerequisites:

• A WordPress site running ThemeREX Hope <= 3.0.0.
• Knowledge of the vulnerable endpoint (e.g., /wp-content/themes/hope/template.php?file=).

Exploitation Steps:

1. Identify the vulnerable parameter by fuzzing the theme's endpoints.
2. Send a request to read wp-config.php:

   GET /wp-content/themes/hope/template.php?file=../../../wp-config
   

3. The server will include the file and output its contents (if PHP is not executed) or return an error with the file path.

Example cURL command:

curl -v "http://target.com/wp-content/themes/hope/template.php?file=../../../wp-config"

Note: No public exploit code is available. The above is a generic example based on the vulnerability type.

Blue Team (Defensive)

Detection:

• Monitor web server logs for requests containing ../ or file= parameters.
• Look for requests to theme files with suspicious query strings.
• Use WAF rules to block path traversal patterns.

Hunting:

• Search for include( or require( in the theme's PHP files.
• Check for unsanitized $_GET or $_POST variables used in file inclusion.

Lab Setup:

1. Install a local WordPress instance with the Hope theme.
2. Create a test page that triggers the vulnerable include.
3. Use Burp Suite or curl to send malicious requests.
4. Monitor logs and system behavior.

Indicators of Compromise (IOCs)

• Network IOCs:

  • HTTP requests containing ../ in query parameters.
  • Requests to theme files like template.php, page.php, or shortcode.php with file= parameters.
  • User-Agent strings from known scanning tools (e.g., curl, python-requests).

• File System IOCs:

  • Unexpected access to /etc/passwd, wp-config.php, or other sensitive files.
  • Modified or new files in the theme directory (if RCE is achieved).

• Log IOCs:

  • Apache/Nginx access logs showing 404 or 200 responses to path traversal attempts.
  • PHP error logs with messages like include(../../../etc/passwd): failed to open stream.

Remediation & Mitigation

Immediate Actions:

1. Disable the Hope theme and switch to a default WordPress theme (e.g., Twenty Twenty-Four) until a patch is available.
2. Implement a Web Application Firewall (WAF) rule to block requests containing ../ or file= parameters in theme URLs.
3. Restrict file permissions on wp-config.php to 400 (read-only for owner) to limit exposure.

Long-term Fix:

• Contact ThemeREX for an official patch.
• If you have development resources, manually audit the theme's PHP files for unsanitized include/require statements and apply the patched code pattern described above.
• Consider replacing the theme with a more secure alternative.

Workaround:

• Add the following rule to .htaccess (Apache) or nginx.conf (Nginx) to block path traversal:

  RewriteEngine On
  RewriteCond %{QUERY_STRING} (\.\./|wp-config) [NC]
  RewriteRule .* - [F,L]
