CVE-2025-48171: Cena Store Path Traversal Vulnerability

CVE-2025-48171 Overview

CVE-2025-48171 is a Local File Inclusion (LFI) vulnerability discovered in the Cena Store WordPress theme developed by thembay. The vulnerability stems from improper control of filename for include/require statements in PHP, which could allow attackers to include local files from the server's filesystem. This type of vulnerability (CWE-98) can potentially lead to sensitive information disclosure, configuration file access, or even remote code execution if combined with other attack techniques such as log poisoning.

Critical Impact

Attackers exploiting this Local File Inclusion vulnerability could read sensitive files from the WordPress server, potentially exposing database credentials, configuration files, or user data stored on the system.

Affected Products

• Cena Store WordPress Theme versions through 2.11.26
• WordPress installations using the vulnerable Cena Store theme
• Websites hosted with PHP configurations allowing local file access

Technical Details for CVE-2025-48171

Vulnerability Analysis

This vulnerability is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Cena Store theme contains code that improperly validates or sanitizes user-supplied input before using it in PHP include or require statements. When exploited, this allows an attacker to manipulate file paths and force the application to include arbitrary local files from the server's filesystem.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because they can be leveraged to:

• Read sensitive WordPress configuration files such as wp-config.php
• Access server configuration files like /etc/passwd on Linux systems
• View log files that may contain sensitive information
• Potentially achieve remote code execution through log poisoning or PHP wrapper techniques

Root Cause

The root cause of this vulnerability lies in insufficient input validation within the Cena Store theme's PHP code. The theme fails to properly sanitize or validate user-controlled input before passing it to PHP's include(), require(), include_once(), or require_once() functions. This allows attackers to use directory traversal sequences (such as ../) to break out of the intended directory and access files elsewhere on the filesystem.

Attack Vector

The attack vector for this vulnerability involves manipulating parameters that are subsequently used in file inclusion operations. An attacker can craft malicious requests containing path traversal sequences to navigate the server's directory structure and include sensitive files.

For example, an attacker might manipulate a theme template parameter to traverse directories and access critical system or WordPress configuration files. The vulnerability could be exploited through GET or POST parameters, depending on how the theme implements its file inclusion logic.

Successful exploitation could result in:

• Disclosure of database credentials from wp-config.php
• Exposure of server configuration and system files
• Potential for chained attacks leading to remote code execution

Detection Methods for CVE-2025-48171

Indicators of Compromise

• Unusual HTTP requests containing path traversal sequences such as ../ or ..%2f targeting theme-related endpoints
• Web server access logs showing attempts to access sensitive files like wp-config.php, /etc/passwd, or .htaccess
• Requests with encoded directory traversal patterns targeting the Cena Store theme directory
• Abnormal file access patterns in PHP or Apache/Nginx logs indicating file inclusion attempts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Monitor web server logs for requests containing directory traversal sequences targeting the /wp-content/themes/cena/ directory
• Deploy intrusion detection systems (IDS) with signatures for PHP Local File Inclusion attack patterns
• Use WordPress security plugins that can detect and alert on suspicious file access attempts

Monitoring Recommendations

• Enable detailed logging for PHP file operations and WordPress theme activity
• Configure SIEM alerts for patterns indicative of LFI exploitation attempts
• Regularly audit access to sensitive files like wp-config.php and system configuration files
• Monitor for unusual read operations on files outside the WordPress web root

How to Mitigate CVE-2025-48171

Immediate Actions Required

• Update the Cena Store theme to the latest patched version immediately if available
• Consider temporarily deactivating the Cena Store theme and switching to a default WordPress theme until a patch is released
• Implement WAF rules to block path traversal attack patterns
• Review web server logs for any signs of exploitation attempts
• Restrict PHP's open_basedir directive to limit file inclusion to the WordPress directory

Patch Information

Users of the Cena Store WordPress theme should check for updates from thembay and apply any security patches as soon as they become available. For the latest patch information, consult the Patchstack Vulnerability Database Entry.

If no patch is currently available, implement the workarounds listed below to reduce risk exposure.

Workarounds

• Configure PHP's open_basedir directive to restrict file access to the WordPress installation directory only
• Implement strict input validation on all user-supplied parameters at the web server level
• Deploy a Web Application Firewall (WAF) with rules to block Local File Inclusion patterns
• Consider using WordPress security plugins like Wordfence or Sucuri to add an additional layer of protection

# PHP Configuration Hardening (php.ini)
# Restrict file operations to WordPress directory
open_basedir = /var/www/html/wordpress/

# Disable dangerous PHP functions if not needed
disable_functions = exec,passthru,shell_exec,system,proc_open,popen

# Apache .htaccess rule to block path traversal attempts
# Add to WordPress root .htaccess file
# RewriteEngine On
# RewriteCond %{QUERY_STRING} (\.\./|\.\.%2f) [NC,OR]
# RewriteCond %{QUERY_STRING} (etc/passwd|proc/self/environ) [NC]
# RewriteRule .* - [F,L]
