CVE-2025-60046: Axiomthemes Heartstar Path Traversal Flaw

CVE-2025-60046 Overview

CVE-2025-60046 is a Local File Inclusion (LFI) vulnerability affecting the HeartStar WordPress theme developed by axiomthemes. This vulnerability arises 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 unauthenticated attackers to potentially access sensitive configuration files, source code, and other critical system resources. By manipulating file path parameters, malicious actors can traverse the directory structure and read files outside the intended scope of the web application.

Critical Impact

Attackers can exploit this LFI vulnerability to read sensitive server files including wp-config.php, potentially exposing database credentials, authentication keys, and other critical WordPress configuration data. This could lead to complete site compromise.

Affected Products

• axiomthemes HeartStar WordPress theme versions through 1.0.14
• WordPress installations using vulnerable HeartStar theme versions
• Web servers hosting affected WordPress sites

Technical Details for CVE-2025-60046

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The HeartStar theme fails to properly validate and sanitize user-supplied input before using it in PHP file inclusion functions such as include(), require(), include_once(), or require_once().

When user-controlled input is passed directly to these functions without adequate validation, attackers can manipulate the file path to include arbitrary files from the local filesystem. This is particularly dangerous in WordPress environments where configuration files contain database credentials and cryptographic keys.

The attack can be executed over the network and requires some user interaction, though it does not require authentication. Successful exploitation can result in complete disclosure of confidential information and potential integrity compromise of the affected system.

Root Cause

The root cause of CVE-2025-60046 is insufficient input validation in the HeartStar theme's PHP code. The vulnerability exists because:

1. User-supplied input is accepted without proper sanitization
2. The input is directly concatenated or used in file path construction
3. No allowlist validation is performed to restrict file inclusion to known-safe paths
4. Directory traversal sequences (such as ../) are not filtered or normalized

This allows attackers to break out of the intended directory context and access files elsewhere on the server filesystem.

Attack Vector

The attack is network-based and can be executed remotely against vulnerable WordPress installations. An attacker crafts a malicious request containing directory traversal sequences to manipulate the file path parameter. The vulnerable PHP code then includes the attacker-specified file, exposing its contents or executing its code within the application context.

Typical exploitation involves requesting paths like ../../../../wp-config.php to traverse up the directory tree and access WordPress configuration files. More sophisticated attacks may target system files like /etc/passwd for reconnaissance or attempt to include log files that have been poisoned with PHP code.

Detection Methods for CVE-2025-60046

Indicators of Compromise

• Unusual HTTP requests containing directory traversal patterns (../, ..%2f, ..%5c) in query parameters or POST data
• Web server access logs showing requests for sensitive file paths such as wp-config.php, /etc/passwd, or similar
• Unexpected file access patterns in WordPress theme directories
• Error logs indicating failed file inclusion attempts with suspicious paths

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block directory traversal sequences in incoming requests
• Monitor web server logs for patterns matching LFI exploitation attempts using regular expressions
• Deploy file integrity monitoring on critical WordPress configuration files
• Use intrusion detection systems with signatures for PHP file inclusion attacks

Monitoring Recommendations

• Enable verbose logging for PHP file operations and monitor for anomalous include/require patterns
• Set up alerts for access to sensitive configuration files from unexpected processes
• Implement real-time log analysis to detect traversal patterns in HTTP requests
• Monitor for sudden increases in 404 errors which may indicate enumeration attempts

How to Mitigate CVE-2025-60046

Immediate Actions Required

• Update the HeartStar WordPress theme to the latest available version that addresses this vulnerability
• If no patch is available, deactivate and remove the HeartStar theme from production WordPress installations
• Review web server access logs for signs of exploitation attempts
• Audit and rotate any credentials that may have been exposed, including database passwords and WordPress secret keys

Patch Information

Organizations should check for updates to the HeartStar theme from axiomthemes and apply any security patches as soon as they become available. For detailed vulnerability information and remediation guidance, refer to the Patchstack Vulnerability Report.

In the absence of an official patch, switching to an alternative WordPress theme that is actively maintained and free of known vulnerabilities is strongly recommended.

Workarounds

• Implement WAF rules to block requests containing directory traversal patterns targeting the HeartStar theme
• Restrict PHP file inclusion functionality at the server level using open_basedir directive to limit accessible directories
• Apply principle of least privilege to web server file permissions, ensuring the web process cannot read sensitive system files
• Consider using a security plugin that can detect and block LFI attempts at the WordPress application layer

# PHP configuration hardening example
# Add to php.ini or .htaccess to restrict file access scope
# This limits PHP's file operations to specific directories

# In php.ini:
open_basedir = /var/www/html:/tmp

# Or in Apache .htaccess:
php_admin_value open_basedir /var/www/html:/tmp
