CVE-2025-69065: Snow Mountain PHP File Inclusion Flaw

CVE-2025-69065 Overview

CVE-2025-69065 is a Local File Inclusion (LFI) vulnerability in the AncoraThemes Snow Mountain WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include local files from the server. This type of vulnerability can lead to sensitive information disclosure, configuration file exposure, and potentially remote code execution when combined with other attack techniques such as log poisoning.

Critical Impact

Attackers can exploit this Local File Inclusion vulnerability to read sensitive server files, potentially exposing credentials, configuration data, and enabling further attacks on the WordPress installation.

Affected Products

• AncoraThemes Snow Mountain WordPress Theme versions through 1.4.3
• WordPress installations using the vulnerable Snow Mountain theme

Technical Details for CVE-2025-69065

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Snow Mountain theme fails to properly sanitize user-supplied input before passing it to PHP's include() or require() functions. This oversight allows an attacker to manipulate the filename parameter to include arbitrary local files from the server's filesystem.

Local File Inclusion vulnerabilities are particularly dangerous in WordPress environments because they can expose sensitive files such as wp-config.php (containing database credentials), .htaccess files, server logs, and other configuration files. When attackers gain access to these files, they can escalate their access to full server compromise.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and sanitization in the Snow Mountain theme's PHP code. The theme accepts user-controllable input that influences file path resolution without properly validating or restricting the allowed file paths. This allows path traversal sequences (such as ../) to be used to navigate outside intended directories and include sensitive system files.

Attack Vector

The attack vector involves manipulating URL parameters or request data that the Snow Mountain theme uses to dynamically include PHP files. An attacker can craft malicious requests containing path traversal sequences to access files outside the intended directory structure. For example, an attacker might attempt to include /etc/passwd on Linux systems or access WordPress configuration files to extract database credentials and security keys.

The vulnerability requires network access to the WordPress installation but may not require authentication, depending on how the vulnerable functionality is exposed. Successful exploitation can lead to information disclosure, and when combined with techniques like log file poisoning or session file inclusion, may escalate to remote code execution.

Detection Methods for CVE-2025-69065

Indicators of Compromise

• Web server access logs containing path traversal sequences such as ../, ..%2f, or %2e%2e/ in requests to theme files
• Unusual requests targeting Snow Mountain theme endpoints with file path parameters
• Error logs showing failed attempts to include non-existent or restricted files
• Unexpected access patterns to sensitive configuration files

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block path traversal patterns in HTTP requests
• Monitor WordPress access logs for requests containing encoded or plain-text directory traversal sequences
• Implement file integrity monitoring on critical WordPress files including wp-config.php
• Configure intrusion detection systems to alert on LFI attack signatures

Monitoring Recommendations

• Enable verbose logging on WordPress and web server to capture detailed request information
• Set up real-time alerting for suspicious file access patterns targeting theme directories
• Regularly audit installed themes and plugins for known vulnerabilities using security scanners
• Monitor for unauthorized changes to WordPress core files and configuration

How to Mitigate CVE-2025-69065

Immediate Actions Required

• Update the Snow Mountain theme to a patched version as soon as one becomes available from AncoraThemes
• If no patch is available, consider temporarily deactivating the Snow Mountain theme and switching to a secure alternative
• Implement WAF rules to block path traversal attack patterns targeting your WordPress installation
• Review server logs for evidence of exploitation attempts

Patch Information

At the time of this writing, users should monitor the Patchstack advisory and AncoraThemes for official patch releases. All versions of Snow Mountain theme through 1.4.3 are confirmed vulnerable.

Workarounds

• Implement server-side restrictions using open_basedir PHP directive to limit file access to the WordPress directory
• Configure web server rules to block requests containing path traversal sequences
• Use a WordPress security plugin with virtual patching capabilities to protect against LFI attacks
• Restrict PHP file inclusion functions using disable_functions if not required by other functionality

# Example Apache .htaccess rule to block path traversal attempts
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.) [NC,OR]
RewriteCond %{QUERY_STRING} (\.\.%2f|%2e%2e) [NC]
RewriteRule .* - [F,L]

# PHP configuration to restrict file access (php.ini or .user.ini)
open_basedir = /var/www/html/wordpress/
