CVE-2025-31064: Vizeon Business Consulting LFI Vulnerability

CVE-2025-31064 Overview

CVE-2025-31064 is a Local File Inclusion (LFI) vulnerability affecting the Vizeon - Business Consulting WordPress theme developed by Gavias. The vulnerability stems from improper control of filename for include/require statements in PHP, classified under CWE-98 (PHP Remote File Inclusion). This flaw allows attackers to include arbitrary local files from the server, potentially leading to sensitive information disclosure, configuration file exposure, or in some scenarios, remote code execution when combined with other attack vectors.

Critical Impact

Attackers can leverage this Local File Inclusion vulnerability to read sensitive files from the WordPress server, including configuration files containing database credentials, API keys, and other critical secrets.

Affected Products

• Vizeon - Business Consulting WordPress Theme versions prior to 1.2.1
• WordPress installations using vulnerable Vizeon theme versions
• Web servers hosting affected WordPress deployments

Technical Details for CVE-2025-31064

Vulnerability Analysis

This vulnerability represents a classic PHP Local File Inclusion flaw where user-controlled input is passed to PHP's include or require functions without adequate validation or sanitization. The Vizeon theme fails to properly restrict which files can be included through its file handling mechanisms, allowing an attacker to traverse the directory structure and include arbitrary files from the local filesystem.

The vulnerability is particularly concerning in WordPress environments where attackers could potentially access sensitive files such as wp-config.php, which contains database credentials, authentication keys, and other critical configuration data. Additionally, if the server stores log files or uploaded content in accessible locations, attackers might leverage this vulnerability to achieve code execution through log poisoning or inclusion of malicious uploaded files.

Root Cause

The root cause of CVE-2025-31064 lies in the improper handling of user-supplied input within PHP include or require statements. The Vizeon theme does not implement sufficient input validation, path normalization, or allowlist-based restrictions on includable files. This allows path traversal sequences (such as ../) to be processed, enabling attackers to break out of intended directories and access files throughout the filesystem. The absence of proper sanitization functions and security controls around dynamic file inclusion creates this exploitable condition.

Attack Vector

The attack vector involves manipulating parameters passed to the vulnerable PHP include functionality within the Vizeon theme. An attacker would craft a malicious request containing path traversal sequences to navigate the server's directory structure and include sensitive files. The attack is typically executed through HTTP requests targeting the vulnerable endpoint, making it remotely exploitable without authentication in many configurations.

The exploitation process generally involves:

1. Identifying the vulnerable parameter accepting file path input
2. Injecting path traversal sequences (e.g., ../../) to navigate to target files
3. Accessing sensitive configuration files or leveraging the inclusion for further attacks
4. Potentially escalating to remote code execution through log poisoning or other techniques

Detection Methods for CVE-2025-31064

Indicators of Compromise

• Unusual file access patterns in web server logs targeting Vizeon theme files with path traversal sequences (e.g., ../../../)
• HTTP requests containing encoded path traversal characters such as %2e%2e%2f or ..%c0%af
• Evidence of sensitive file reads in access logs including paths to wp-config.php, /etc/passwd, or similar system files
• Unexpected error messages revealing file system paths in server responses

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block path traversal attempts targeting WordPress theme endpoints
• Implement file integrity monitoring on critical WordPress configuration files to detect unauthorized access
• Configure intrusion detection systems (IDS) with signatures for Local File Inclusion attack patterns
• Enable detailed logging on the web server and monitor for requests containing suspicious path traversal sequences

Monitoring Recommendations

• Monitor web server access logs for requests to Vizeon theme files containing unusual characters or traversal patterns
• Set up alerts for failed file access attempts that may indicate reconnaissance or exploitation attempts
• Review PHP error logs for include/require failures that might indicate LFI exploitation attempts
• Implement centralized logging with real-time analysis capabilities for rapid threat detection

How to Mitigate CVE-2025-31064

Immediate Actions Required

• Update the Vizeon - Business Consulting WordPress theme to version 1.2.1 or later immediately
• Review web server access logs for signs of prior exploitation attempts
• Rotate credentials stored in wp-config.php if compromise is suspected
• Implement temporary WAF rules to block path traversal attempts while patching is underway

Patch Information

The vulnerability has been addressed in Vizeon - Business Consulting theme version 1.2.1. Site administrators should update to this version or later through the WordPress theme management interface or by manually downloading the patched version from the official source. After updating, verify the theme version is correctly reflected in the WordPress admin panel. For additional details on the vulnerability and patch status, consult the Patchstack WordPress Vulnerability Report.

Workarounds

• Deploy a Web Application Firewall with rules to block requests containing path traversal patterns
• Restrict access to WordPress admin and theme functionality to trusted IP addresses if updating is not immediately possible
• Implement PHP's open_basedir directive to restrict file access to the WordPress installation directory
• Consider temporarily disabling or replacing the Vizeon theme until patching can be completed

# Configuration example - Apache mod_rewrite rules to block path traversal
# Add to .htaccess in WordPress root directory
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.\\) [NC,OR]
RewriteCond %{QUERY_STRING} (%2e%2e%2f|%2e%2e/) [NC,OR]
RewriteCond %{QUERY_STRING} (\.\.%c0%af|\.\.%c1%9c) [NC]
RewriteRule .* - [F,L]
