CVE-2025-14430: Thememove Brook Path Traversal Vulnerability

CVE-2025-14430 Overview

CVE-2025-14430 is a critical PHP Local File Inclusion (LFI) vulnerability affecting the ThemeMove Brook - Agency Business Creative WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files from the web server. This flaw can be exploited remotely without authentication, potentially leading to sensitive data exposure, arbitrary code execution, and complete server compromise.

Critical Impact

Unauthenticated attackers can exploit this PHP Local File Inclusion vulnerability to read sensitive files, including configuration files containing database credentials, and potentially achieve remote code execution on WordPress sites using the Brook theme.

Affected Products

• ThemeMove Brook - Agency Business Creative (WordPress Theme) versions up to and including 2.8.9

Technical Details for CVE-2025-14430

Vulnerability Analysis

This vulnerability belongs to the CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program) weakness category. The Brook WordPress theme fails to properly sanitize user-supplied input before passing it to PHP's include or require functions. This allows an attacker to manipulate file path parameters to traverse directories and include arbitrary local files from the server's filesystem.

The vulnerability is particularly severe because it can be exploited remotely over the network without requiring any authentication or user interaction. Successful exploitation can result in complete compromise of confidentiality, integrity, and availability of the affected WordPress installation and potentially the underlying server.

Root Cause

The root cause of this vulnerability lies in insufficient input validation within the Brook theme's PHP code. When processing user-supplied data that determines which files to include, the theme fails to implement proper path validation, sanitization, or allowlist restrictions. This allows malicious path traversal sequences (such as ../) to be injected into file paths, enabling attackers to escape the intended directory structure and access sensitive files elsewhere on the server.

Attack Vector

The attack is conducted over the network by sending specially crafted HTTP requests to vulnerable endpoints in the Brook theme. An attacker can construct malicious requests containing path traversal sequences to read sensitive files such as wp-config.php, which contains database credentials and WordPress secret keys. In more advanced scenarios, if the attacker can combine LFI with file upload capabilities or log poisoning techniques, they may achieve remote code execution.

Typical exploitation involves manipulating URL parameters or POST data to include references like ../../wp-config.php or leveraging PHP wrappers such as php://filter to encode and extract file contents. Since no authentication is required, any internet-accessible WordPress site running a vulnerable version of the Brook theme is at risk.

Detection Methods for CVE-2025-14430

Indicators of Compromise

• Unusual HTTP requests containing path traversal sequences (e.g., ../, ..%2f) targeting theme-related endpoints
• Access log entries showing attempts to read sensitive files like wp-config.php, /etc/passwd, or other system files
• Requests containing PHP wrapper protocols such as php://filter, php://input, or file://
• Unexpected file access patterns or error logs indicating failed file inclusion attempts

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block path traversal attempts in HTTP requests
• Monitor WordPress access logs for requests targeting the Brook theme directory with suspicious path patterns
• Implement file integrity monitoring (FIM) on critical WordPress configuration files
• Configure intrusion detection systems (IDS) to alert on LFI attack signatures

Monitoring Recommendations

• Enable detailed logging for all HTTP requests to WordPress installations using the Brook theme
• Set up alerts for access attempts to sensitive configuration files from web-accessible directories
• Monitor for unusual PHP error messages that may indicate exploitation attempts
• Regularly review web server logs for anomalous request patterns targeting theme endpoints

How to Mitigate CVE-2025-14430

Immediate Actions Required

• Immediately audit all WordPress installations for the presence of the Brook theme version 2.8.9 or earlier
• Consider temporarily disabling or replacing the Brook theme until a patched version is available
• Implement WAF rules to block path traversal attempts targeting the theme's vulnerable endpoints
• Restrict file permissions on sensitive WordPress files such as wp-config.php
• Review server logs for any signs of prior exploitation attempts

Patch Information

At the time of publication, administrators should consult the Patchstack WordPress vulnerability database for the latest patching information and updates from ThemeMove. It is strongly recommended to upgrade to a patched version as soon as one becomes available from the vendor.

Workarounds

• Deploy a Web Application Firewall (WAF) with rules specifically designed to block PHP file inclusion attacks
• Implement strict open_basedir restrictions in PHP configuration to limit file access to the WordPress directory
• Use a security plugin that provides virtual patching capabilities for WordPress themes
• If the theme functionality is not critical, consider temporarily switching to a different WordPress theme
• Disable directory listing and ensure proper file permissions are set across the WordPress installation

# PHP configuration hardening example
# Add to php.ini or .user.ini to restrict file access

# Restrict PHP file operations to specific directories
open_basedir = /var/www/html/yoursite/:/tmp/

# Disable dangerous PHP functions that could aid exploitation
disable_functions = exec,passthru,shell_exec,system,proc_open,popen

# Enable strict mode for include paths
allow_url_include = Off
allow_url_fopen = Off
