CVE-2025-58901: Ancorathemes Takeout Path Traversal Flaw

CVE-2025-58901 Overview

CVE-2025-58901 is a PHP Local File Inclusion (LFI) vulnerability affecting the AncoraThemes Takeout WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, which allows attackers to include arbitrary local files from the server. This could enable unauthorized access to sensitive configuration files, disclosure of source code, or potential remote code execution when combined with other attack vectors such as log poisoning.

Critical Impact

Unauthenticated attackers can exploit this vulnerability to read sensitive local files on WordPress installations using the Takeout theme, potentially exposing database credentials, API keys, and other confidential data stored in configuration files.

Affected Products

• AncoraThemes Takeout WordPress theme version 1.3.0 and earlier
• WordPress installations utilizing the Takeout theme

Technical Details for CVE-2025-58901

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The core issue lies in the theme's handling of user-supplied input when constructing file paths for PHP include or require statements. Without proper validation or sanitization of these filename parameters, an attacker can manipulate the input to traverse directory structures and include arbitrary files from the local filesystem.

The network-accessible nature of this vulnerability means it can be exploited remotely by any attacker who can send HTTP requests to the vulnerable WordPress installation. While exploitation requires specific conditions to be met, successful attacks can lead to complete compromise of confidentiality and integrity of the affected system.

Root Cause

The root cause of CVE-2025-58901 is insufficient input validation in the AncoraThemes Takeout theme. The vulnerable code accepts user-controlled input for file path construction without adequately filtering directory traversal sequences (such as ../) or validating that the requested file exists within an expected directory. This allows attackers to escape the intended directory scope and access files elsewhere on the server.

Attack Vector

The attack can be executed remotely over the network without requiring authentication. An attacker crafts malicious HTTP requests containing directory traversal sequences in parameters that are used for file inclusion operations. Common targets include:

• WordPress configuration file (wp-config.php) containing database credentials
• System files such as /etc/passwd for user enumeration
• Log files that may contain injected PHP code for remote code execution
• Other PHP files containing sensitive application logic or credentials

The vulnerability mechanism involves manipulating file path parameters in HTTP requests to the WordPress theme. By injecting directory traversal sequences, attackers can navigate outside the intended directory and include sensitive files. For detailed technical information, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-58901

Indicators of Compromise

• Unusual HTTP requests containing directory traversal patterns (../, ..%2f, ..%252f) targeting the Takeout theme endpoints
• Access log entries showing requests for sensitive files like wp-config.php or /etc/passwd through theme parameters
• Unexpected file access patterns in PHP error logs indicating failed or successful file inclusion attempts
• Evidence of log file poisoning attempts with embedded PHP code

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block directory traversal sequences in HTTP parameters
• Monitor web server access logs for requests containing path traversal patterns targeting WordPress theme directories
• Deploy file integrity monitoring on critical WordPress configuration files
• Enable PHP error logging and monitor for include/require failures on unexpected file paths

Monitoring Recommendations

• Configure real-time alerting for HTTP requests matching known LFI attack patterns
• Monitor for unusual file read operations from the web server process on sensitive system files
• Track access patterns to WordPress theme files for anomalous behavior
• Review web application logs for repeated failed attempts to access restricted files

How to Mitigate CVE-2025-58901

Immediate Actions Required

• Disable or remove the AncoraThemes Takeout theme if it is not critical to site operations
• Implement Web Application Firewall rules to block directory traversal attempts
• Restrict file system permissions to limit web server access to only necessary directories
• Review server logs for evidence of exploitation attempts

Patch Information

As of the last update, WordPress administrators should check for an updated version of the AncoraThemes Takeout theme that addresses this vulnerability. Monitor the Patchstack Vulnerability Report for patch availability and vendor communications. If no patch is available, consider switching to an alternative theme until a security update is released.

Workarounds

• Deploy a WAF with rules specifically designed to detect and block PHP Local File Inclusion attacks
• Use PHP open_basedir configuration to restrict file access to the WordPress installation directory
• Implement ModSecurity or similar security modules with OWASP Core Rule Set to filter malicious requests
• Apply principle of least privilege to web server user permissions

# PHP configuration hardening example (php.ini)
# Restrict file access to WordPress directory only
open_basedir = /var/www/html/wordpress:/tmp

# Disable dangerous PHP functions that may aid exploitation
