CVE-2025-60061: Axiomthemes Kicker Path Traversal Flaw

CVE-2025-60061 Overview

CVE-2025-60061 is a PHP Local File Inclusion (LFI) vulnerability affecting the Axiomthemes Kicker WordPress theme. This vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files from the server filesystem. The vulnerability enables unauthorized access to sensitive files and could potentially lead to remote code execution under certain conditions.

Critical Impact

Successful exploitation allows attackers to read sensitive server files, access configuration data, and potentially achieve remote code execution through log poisoning or other LFI-to-RCE techniques.

Affected Products

• Axiomthemes Kicker WordPress Theme versions up to and including 2.2.0
• WordPress installations running the vulnerable Kicker theme

Technical Details for CVE-2025-60061

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Kicker 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 include arbitrary files from the local filesystem.

Local File Inclusion vulnerabilities in PHP applications are particularly dangerous because they can expose sensitive configuration files such as wp-config.php, which contains database credentials, authentication keys, and other critical WordPress configuration data. Additionally, if an attacker can control the contents of any file on the system (such as through log poisoning), they may be able to escalate the LFI to achieve remote code execution.

The network-accessible nature of this vulnerability means any unauthenticated attacker who can reach the WordPress installation can potentially exploit this flaw without requiring any user interaction or special privileges.

Root Cause

The root cause lies in insufficient input validation and sanitization within the Kicker theme's file handling logic. When processing requests that involve dynamic file inclusion, the theme does not adequately validate or sanitize the filename parameter, allowing path traversal sequences and arbitrary file paths to be processed by PHP's include/require statements.

Attack Vector

The vulnerability is exploitable over the network without authentication. An attacker can craft malicious HTTP requests containing path traversal sequences (such as ../) or direct file paths to force the PHP application to include unintended files. Common targets include:

• WordPress configuration files (wp-config.php)
• System files (/etc/passwd on Linux systems)
• Application log files for potential RCE via log poisoning
• Other sensitive PHP files within the web root

The vulnerability description indicates this is specifically a Local File Inclusion vulnerability, meaning the attacker can include files present on the target server but cannot directly include remote files from external URLs.

Detection Methods for CVE-2025-60061

Indicators of Compromise

• Unusual HTTP requests to WordPress theme files containing path traversal sequences (../, ..%2f, etc.)
• Web server logs showing requests with file path parameters pointing to sensitive system or configuration files
• Requests attempting to access /etc/passwd, wp-config.php, or other sensitive files through theme endpoints
• Error messages or responses containing file contents that should not be accessible

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 suspicious path manipulation sequences
• Deploy file integrity monitoring on critical WordPress configuration files
• Use intrusion detection systems with signatures for PHP Local File Inclusion attacks

Monitoring Recommendations

• Enable detailed logging for the WordPress installation and review logs for anomalous file access patterns
• Monitor for unusual read access to sensitive files like wp-config.php or system configuration files
• Set up alerts for HTTP requests containing common LFI payloads targeting the Kicker theme directory

How to Mitigate CVE-2025-60061

Immediate Actions Required

• Update the Axiomthemes Kicker theme to a patched version immediately if one is available
• If no patch is available, consider temporarily deactivating the Kicker theme until a fix is released
• Implement WAF rules to block path traversal attempts targeting WordPress theme files
• Review web server logs for evidence of exploitation attempts

Patch Information

Users should monitor the Patchstack Kicker Theme Vulnerability advisory for updates on patch availability from Axiomthemes. Check the official WordPress theme repository or the Axiomthemes website for security updates to versions newer than 2.2.0.

Workarounds

• Deploy a Web Application Firewall with rules to block common LFI patterns and path traversal sequences
• Restrict filesystem permissions to limit what files the web server process can read
• Implement PHP open_basedir restrictions to confine PHP file operations to the WordPress directory
• Consider using WordPress security plugins that provide virtual patching capabilities for vulnerable themes

# Example PHP configuration to restrict file access (php.ini or .htaccess)
# Restrict PHP file operations to WordPress directory only
php_value open_basedir /var/www/html/wordpress/

# Or via Apache configuration
<Directory /var/www/html/wordpress>
    php_admin_value open_basedir /var/www/html/wordpress/
</Directory>
