CVE-2024-54263: Spirit Framework LFI Vulnerability

CVE-2024-54263 Overview

CVE-2024-54263 is a Local File Inclusion (LFI) vulnerability affecting the Talemy Spirit Framework WordPress plugin. The vulnerability stems from improper control of filename for include/require statements in PHP (CWE-98), allowing authenticated attackers to include local files on the server. This can potentially lead to sensitive information disclosure, arbitrary code execution, or complete system compromise depending on the server configuration and accessible files.

Critical Impact

Authenticated attackers can exploit this LFI vulnerability to read sensitive server files, potentially including configuration files containing database credentials, or achieve code execution by including files containing malicious PHP code.

Affected Products

• Talemy Spirit Framework plugin for WordPress versions through 1.2.13

Technical Details for CVE-2024-54263

Vulnerability Analysis

This vulnerability exists due to improper validation and sanitization of user-supplied input that is used in PHP file inclusion functions. When a PHP application uses include(), require(), include_once(), or require_once() functions with user-controllable input without proper validation, attackers can manipulate the file path to include arbitrary files from the local filesystem.

The Spirit Framework plugin fails to adequately restrict the filename parameter used in these PHP inclusion statements, enabling authenticated users to traverse directories and access files outside the intended scope. This type of vulnerability requires network access and low-privilege authentication to exploit, though the attack complexity is considered high due to the specific conditions required for successful exploitation.

Root Cause

The root cause of CVE-2024-54263 is the improper control of filename for include/require statements in PHP programs. The Spirit Framework plugin does not implement sufficient input validation or path normalization before passing user-controlled data to PHP file inclusion functions. This allows attackers to use path traversal sequences (such as ../) to escape the intended directory context and include sensitive files from elsewhere on the server.

Attack Vector

The attack is network-based and requires the attacker to have authenticated access to the WordPress installation with at least low-level privileges. The attacker crafts a malicious request containing path traversal sequences targeting the vulnerable inclusion point in the Spirit Framework plugin. By manipulating the filename parameter, the attacker can force the server to include arbitrary local files such as /etc/passwd, WordPress configuration files (wp-config.php), or potentially PHP session files that could lead to code execution.

Detection Methods for CVE-2024-54263

Indicators of Compromise

• Unusual file access patterns in web server logs showing path traversal sequences (../, ..%2f, %2e%2e/)
• HTTP requests to the Spirit Framework plugin endpoints containing suspicious file path parameters
• Unexpected read access to sensitive system files such as /etc/passwd, wp-config.php, or log files
• Error logs showing failed file inclusion attempts from unusual directory paths

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Monitor web server access logs for requests containing directory traversal sequences targeting the Spirit Framework plugin
• Deploy file integrity monitoring on sensitive configuration files to detect unauthorized access
• Use SentinelOne's behavioral AI to identify anomalous file access patterns indicative of LFI exploitation

Monitoring Recommendations

• Enable detailed logging for all WordPress plugin activities, particularly file operations
• Configure alerts for access attempts to sensitive files from web server processes
• Monitor for unusual outbound connections that may indicate data exfiltration following successful exploitation
• Implement real-time log analysis to detect patterns consistent with LFI probing and exploitation attempts

How to Mitigate CVE-2024-54263

Immediate Actions Required

• Update the Spirit Framework plugin to a patched version when available from the vendor
• Implement input validation and sanitization for all user-controllable parameters at the application level
• Deploy a Web Application Firewall (WAF) with rules to block path traversal attacks
• Review and restrict file system permissions to limit the impact of potential exploitation
• Consider temporarily disabling the Spirit Framework plugin if not critical to operations until a patch is available

Patch Information

At the time of publication, organizations should monitor the Patchstack Security Vulnerability Report for updates on available patches. Users of Spirit Framework version 1.2.13 and earlier should update to the latest version as soon as a security fix is released by the vendor.

Workarounds

• Configure open_basedir in PHP to restrict file access to the WordPress directory and necessary system paths only
• Implement server-level access controls to prevent web processes from reading sensitive configuration files
• Use a WAF rule to block requests containing path traversal patterns targeting the Spirit Framework plugin
• Disable direct access to plugin files by configuring appropriate .htaccess rules

# PHP configuration hardening example
# Add to php.ini to restrict file access scope
open_basedir = /var/www/html:/tmp

# Apache .htaccess rule to block path traversal attempts
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.\\) [NC,OR]
RewriteCond %{QUERY_STRING} (\.\.%2f|\.\.%5c) [NC]
RewriteRule .* - [F,L]
