CVE-2025-60048: Tripster Path Traversal Vulnerability

CVE-2025-60048 Overview

CVE-2025-60048 is a Local File Inclusion (LFI) vulnerability affecting the Tripster WordPress theme developed by axiomthemes. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files from the server's filesystem. This type of vulnerability can lead to sensitive information disclosure, including configuration files containing database credentials, and may potentially be chained with other vulnerabilities to achieve remote code execution.

Critical Impact

Attackers can exploit this vulnerability to read sensitive server files, potentially exposing database credentials, WordPress configuration files, and other confidential data without requiring authentication.

Affected Products

• Axiomthemes Tripster WordPress Theme version 1.0.10 and earlier
• WordPress installations using the Tripster theme
• All sites with affected theme versions regardless of WordPress core version

Technical Details for CVE-2025-60048

Vulnerability Analysis

This vulnerability is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Tripster theme fails to properly sanitize user-controlled input before using it in PHP include or require statements. When a theme accepts user input to dynamically include files without adequate validation, attackers can manipulate the file path to include unintended files from the local filesystem.

The attack requires network access and user interaction, but does not require authentication. Successful exploitation can result in unauthorized access to sensitive files on the web server, potentially compromising both confidentiality and integrity of the system.

Root Cause

The root cause lies in insufficient input validation and sanitization of file path parameters within the Tripster theme's PHP code. The theme likely accepts a parameter that influences which file gets included via PHP's include(), require(), include_once(), or require_once() functions. Without proper validation against directory traversal sequences (such as ../) or allowlist-based path restrictions, attackers can traverse the filesystem and include arbitrary files.

Attack Vector

The attack is network-based, meaning it can be initiated remotely against vulnerable WordPress installations. An attacker would craft a malicious HTTP request containing directory traversal sequences or manipulated file paths targeting the vulnerable theme component. Common attack payloads include attempts to read sensitive files such as:

• /etc/passwd on Linux servers
• wp-config.php containing WordPress database credentials
• .htaccess files containing security configurations
• Log files that might contain sensitive information

The vulnerability is exploited by manipulating URL parameters or POST data that the theme uses to determine which file to include. By injecting path traversal sequences, attackers can escape the intended directory and access files elsewhere on the server.

Detection Methods for CVE-2025-60048

Indicators of Compromise

• Unusual HTTP requests containing directory traversal patterns (../, ..%2f, %2e%2e/) targeting theme files
• Access log entries showing requests for sensitive system files through theme endpoints
• Unexpected file access patterns in WordPress theme directories
• Error logs indicating failed file inclusion attempts from unexpected paths

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block directory traversal patterns in requests targeting WordPress themes
• Monitor HTTP request logs for unusual file path parameters containing traversal sequences
• Deploy file integrity monitoring on critical WordPress configuration files
• Configure intrusion detection systems to alert on LFI attack signatures targeting the Tripster theme

Monitoring Recommendations

• Enable detailed access logging for the WordPress installation to capture all requests to theme files
• Set up alerts for requests containing common LFI payloads such as ../, encoded traversal sequences, or references to system files
• Monitor for unusual outbound data transfers that could indicate successful data exfiltration
• Review theme file access patterns for anomalies indicating exploitation attempts

How to Mitigate CVE-2025-60048

Immediate Actions Required

• Update the Tripster theme to a patched version as soon as one becomes available from axiomthemes
• If no patch is available, consider temporarily disabling or replacing the Tripster theme with a secure alternative
• Implement WAF rules to block directory traversal attempts targeting WordPress theme components
• Restrict file permissions on sensitive configuration files to minimize exposure if exploitation occurs

Patch Information

Refer to the Patchstack vulnerability database entry for the latest information on available patches and vendor advisories. Version 1.0.10 and earlier are confirmed vulnerable. Contact axiomthemes directly for information about security updates.

Workarounds

• Deploy a Web Application Firewall with rules specifically blocking LFI attack patterns targeting WordPress themes
• Implement PHP configuration hardening by disabling dangerous functions and enabling open_basedir restrictions
• Use file permission restrictions to prevent the web server from reading sensitive files outside the web root
• Consider using WordPress security plugins that provide virtual patching capabilities for known vulnerabilities

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

# Restrict PHP file operations to WordPress directory
open_basedir = /var/www/html/wordpress/

# Disable dangerous functions
disable_functions = exec,passthru,shell_exec,system,proc_open,popen

# Log all errors for monitoring
log_errors = On
error_log = /var/log/php/error.log
