CVE-2025-69072: Prider WordPress Theme LFI Vulnerability

CVE-2025-69072 Overview

CVE-2025-69072 is a PHP Local File Inclusion (LFI) vulnerability affecting the AncoraThemes Prider WordPress theme. 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.

Critical Impact

This Local File Inclusion vulnerability could allow attackers to read sensitive files, execute arbitrary PHP code, or potentially achieve remote code execution through log poisoning or other LFI-to-RCE techniques on WordPress installations using the vulnerable Prider theme.

Affected Products

• AncoraThemes Prider WordPress Theme versions up to and including 1.1.3.1

Technical Details for CVE-2025-69072

Vulnerability Analysis

This vulnerability is classified under CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program. The Prider WordPress theme fails to properly sanitize user-supplied input before passing it to PHP's include or require functions. This allows attackers to manipulate file path parameters to include arbitrary files from the local filesystem.

Local File Inclusion vulnerabilities in PHP applications are particularly dangerous because they can be leveraged in multiple ways: reading sensitive configuration files (such as wp-config.php containing database credentials), accessing server logs, or potentially achieving code execution through techniques like log poisoning or PHP session file inclusion.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and sanitization of user-controlled parameters that are subsequently used in PHP file inclusion operations. The theme code does not properly restrict or validate the file paths that can be specified, allowing path traversal sequences (such as ../) to navigate outside intended directories.

Attack Vector

An attacker can exploit this vulnerability by crafting malicious requests that manipulate file path parameters. By using directory traversal sequences, the attacker can navigate the filesystem and include sensitive files. For WordPress installations, this could expose the wp-config.php file containing database credentials, WordPress secret keys, and other sensitive configuration data.

The attack can be escalated from simple file disclosure to remote code execution through various techniques:

• Log Poisoning: Injecting PHP code into server logs, then including those log files
• Session File Inclusion: Manipulating PHP session data to include malicious code
• Proc/Self/Environ: On vulnerable Linux configurations, accessing environment variables through /proc/self/environ

Detection Methods for CVE-2025-69072

Indicators of Compromise

• Web server access logs containing path traversal sequences (../, ..%2f, ..%252f) targeting the Prider theme
• Unusual requests attempting to access system files like /etc/passwd, wp-config.php, or log files through theme endpoints
• Error logs showing failed file inclusion attempts or unexpected file access patterns
• Evidence of log poisoning attempts with embedded PHP code in User-Agent or Referer headers

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block path traversal patterns in requests targeting WordPress theme files
• Monitor web server logs for requests containing file inclusion indicators such as null bytes (%00), path traversal sequences, or references to sensitive files
• Implement file integrity monitoring on WordPress installations to detect unauthorized file access or modifications
• Configure intrusion detection systems to alert on LFI attack patterns targeting the /wp-content/themes/prider/ directory

Monitoring Recommendations

• Enable verbose logging for the WordPress installation and review logs regularly for suspicious file access attempts
• Set up automated alerts for requests matching known LFI attack signatures
• Monitor for unusual PHP process activity that could indicate successful code execution through LFI exploitation

How to Mitigate CVE-2025-69072

Immediate Actions Required

• Update the Prider WordPress theme to a patched version if available, or deactivate the theme until a fix is released
• Implement Web Application Firewall rules to block path traversal attempts
• Review web server access logs for any signs of exploitation attempts
• Audit WordPress file permissions to restrict access to sensitive configuration files

Patch Information

As of the published date, users should check the Patchstack WordPress Vulnerability Report for the latest patch status and remediation guidance. Contact the theme vendor AncoraThemes for information on updated versions that address this vulnerability.

Workarounds

• Temporarily deactivate the Prider theme and switch to a secure alternative theme until a patch is available
• Implement strict WAF rules to filter and block requests containing path traversal sequences
• Restrict PHP's open_basedir directive to limit file access to the WordPress directory only
• Consider using a WordPress security plugin that provides virtual patching capabilities for known vulnerabilities

# Add to .htaccess to block common LFI patterns (Apache)
RewriteEngine On
RewriteCond %{QUERY_STRING} \.\.[\/\\] [NC,OR]
RewriteCond %{QUERY_STRING} boot\.ini [NC,OR]
RewriteCond %{QUERY_STRING} etc/passwd [NC,OR]
RewriteCond %{QUERY_STRING} self/environ [NC]
RewriteRule .* - [F,L]

# PHP open_basedir restriction (php.ini or .user.ini)
# open_basedir = /var/www/html/wordpress/
