CVE-2025-67941: The Aisle Theme LFI Vulnerability

CVE-2025-67941 Overview

CVE-2025-67941 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability affecting the Elated-Themes "The Aisle" WordPress theme. This PHP Local File Inclusion (LFI) vulnerability allows attackers to manipulate file paths in PHP include or require statements, potentially enabling unauthorized access to sensitive files on the server.

Critical Impact

Attackers can exploit this Local File Inclusion vulnerability to read sensitive configuration files, access credentials, or potentially achieve remote code execution through log poisoning or other chaining techniques.

Affected Products

• Elated-Themes The Aisle WordPress Theme versions prior to 2.9.1
• WordPress installations using vulnerable versions of The Aisle theme

Technical Details for CVE-2025-67941

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The flaw exists in The Aisle WordPress theme where user-controlled input is improperly sanitized before being used in PHP include or require statements. When exploited, attackers can traverse directory structures and include arbitrary local files from the web server's filesystem.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because they can expose sensitive files such as wp-config.php, which contains database credentials and authentication keys. Additionally, attackers may chain this vulnerability with other techniques to achieve remote code execution.

Root Cause

The root cause stems from insufficient input validation and sanitization of user-supplied data that is subsequently passed to PHP's file inclusion functions (include, include_once, require, or require_once). The Aisle theme fails to properly restrict or validate the file path parameter, allowing attackers to use directory traversal sequences (such as ../) to escape the intended directory and access files elsewhere on the server.

Attack Vector

The attack vector involves manipulating HTTP request parameters that are passed to PHP file inclusion functions within The Aisle theme. An attacker can craft malicious requests containing directory traversal sequences to include arbitrary files from the local filesystem.

The vulnerability manifests in file inclusion functions where user input is not properly validated. An attacker could potentially include files such as /etc/passwd on Linux systems or wp-config.php to extract sensitive configuration data.

Detection Methods for CVE-2025-67941

Indicators of Compromise

• HTTP requests containing directory traversal patterns such as ../, ..%2f, or ..%252f targeting The Aisle theme files
• Unusual access attempts to sensitive files like /etc/passwd, wp-config.php, or log files through theme endpoints
• Anomalous file read operations originating from the WordPress web application process
• Error logs showing failed file inclusion attempts with traversal patterns

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block directory traversal patterns in requests targeting WordPress themes
• Monitor web server access logs for requests containing ../ sequences or encoded variants targeting The Aisle theme
• Deploy file integrity monitoring to detect unauthorized access to sensitive configuration files
• Enable PHP error logging and monitor for file inclusion warnings or errors

Monitoring Recommendations

• Configure real-time alerting for requests matching LFI attack patterns against WordPress installations
• Monitor process activity for the web server user accessing files outside expected directories
• Implement log analysis for unusual file access patterns from WordPress theme components
• Review access logs for requests to The Aisle theme endpoints with suspicious parameters

How to Mitigate CVE-2025-67941

Immediate Actions Required

• Update The Aisle WordPress theme to version 2.9.1 or later immediately
• If immediate patching is not possible, temporarily disable The Aisle theme and switch to a secure alternative
• Review web server logs for any evidence of exploitation attempts
• Audit WordPress installations to identify all instances using vulnerable versions of The Aisle theme

Patch Information

The vulnerability has been addressed in The Aisle theme version 2.9.1. Administrators should update the theme through the WordPress admin dashboard or by downloading the latest version from the theme vendor. For additional details on the vulnerability and patch, refer to the Patchstack vulnerability database.

Workarounds

• Deploy a Web Application Firewall (WAF) with rules to block directory traversal attempts targeting WordPress themes
• Restrict file system permissions to limit the web server user's access to only necessary files
• Disable direct access to PHP files in the theme directory using .htaccess rules where applicable
• Implement PHP open_basedir restriction to limit PHP file operations to the WordPress directory

# Example .htaccess configuration to restrict direct PHP file access in themes directory
<Directory /var/www/html/wp-content/themes/theaisle>
    <FilesMatch "\.php$">
        Order Deny,Allow
        Deny from all
    </FilesMatch>
</Directory>

# PHP open_basedir configuration example (php.ini)
open_basedir = /var/www/html/:/tmp/
