CVE-2025-32631: Oxygen MyData Path Traversal Vulnerability

CVE-2025-32631 Overview

CVE-2025-32631 is a Path Traversal vulnerability (CWE-22) affecting the Oxygen MyData for WooCommerce WordPress plugin developed by oxygensuite. This vulnerability allows attackers to improperly manipulate file paths to access or delete files outside of the intended directory structure. The flaw stems from improper limitation of a pathname to a restricted directory, enabling arbitrary file deletion capabilities that could severely impact system availability.

Critical Impact

This vulnerability enables unauthenticated attackers to perform arbitrary file deletion through path traversal, potentially leading to complete denial of service by deleting critical WordPress files.

Affected Products

• Oxygen MyData for WooCommerce plugin versions up to and including 1.0.64
• WordPress installations running vulnerable versions of the oxygen-mydata plugin
• WooCommerce stores utilizing Oxygen MyData integration

Technical Details for CVE-2025-32631

Vulnerability Analysis

This Path Traversal vulnerability exists in the Oxygen MyData for WooCommerce plugin, which is used for integrating WooCommerce stores with the Greek MyData electronic invoicing system. The vulnerability allows an attacker to traverse directory paths and access files outside of the web application's root directory.

The core issue lies in insufficient validation of user-supplied file path input. When the plugin processes file operations, it fails to properly sanitize path sequences such as ../ (dot-dot-slash), allowing attackers to escape the intended directory and target arbitrary files on the filesystem. This can be exploited remotely without any authentication or user interaction, making it particularly dangerous for exposed WordPress installations.

The vulnerability specifically enables arbitrary file deletion, which could be leveraged to remove critical WordPress core files (such as wp-config.php), effectively taking down the entire website or triggering WordPress's installation wizard, which could then be exploited for further compromise.

Root Cause

The root cause of CVE-2025-32631 is the improper limitation of a pathname to a restricted directory within the Oxygen MyData plugin's file handling functionality. The plugin fails to implement proper input validation and path canonicalization before processing file operations. Specifically, the code does not adequately strip or reject directory traversal sequences (../, ..\, or URL-encoded variants) from user-controlled input that is used to construct file paths.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability by:

1. Crafting malicious HTTP requests to the vulnerable WordPress endpoint
2. Including path traversal sequences in file path parameters
3. Targeting critical system or WordPress files for deletion
4. Causing denial of service by removing essential configuration files

The vulnerability manifests in the plugin's file handling mechanisms where user input is used to construct file paths without proper sanitization. Attackers can leverage sequences like ../../../wp-config.php to traverse out of the intended directory and target critical WordPress files.

Detection Methods for CVE-2025-32631

Indicators of Compromise

• Unexpected HTTP requests containing path traversal sequences (../, ..%2f, ..%5c) targeting the oxygen-mydata plugin endpoints
• Missing critical WordPress files such as wp-config.php, .htaccess, or plugin configuration files
• Web server logs showing repeated requests with directory traversal patterns
• WordPress site experiencing sudden availability issues or displaying installation wizard

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block requests containing path traversal sequences
• Monitor WordPress error logs for file-not-found errors on critical system files
• Deploy file integrity monitoring solutions to detect unauthorized file deletions
• Review web server access logs for suspicious patterns targeting /wp-content/plugins/oxygen-mydata/ paths

Monitoring Recommendations

• Enable detailed logging for WordPress plugin activities and file operations
• Set up alerts for changes to critical WordPress configuration files
• Monitor for unusual patterns in HTTP request parameters, particularly those containing encoded path sequences
• Implement real-time file integrity checking for WordPress core files and configurations

How to Mitigate CVE-2025-32631

Immediate Actions Required

• Update Oxygen MyData for WooCommerce plugin to a patched version (newer than 1.0.64) immediately
• If updates are not available, temporarily disable the oxygen-mydata plugin until a fix is released
• Implement WAF rules to block requests containing path traversal patterns targeting WordPress plugins
• Review recent access logs for potential exploitation attempts

Patch Information

Organizations should check for updates to the Oxygen MyData for WooCommerce plugin through the WordPress plugin repository or the vendor's official channels. Monitor the Patchstack Vulnerability Report for updated patch information. Until a patch is available, implement the workarounds described below.

Workarounds

• Temporarily deactivate the Oxygen MyData for WooCommerce plugin if not critical for business operations
• Implement server-level restrictions to filter requests containing path traversal sequences
• Configure ModSecurity or similar WAF rules to block common path traversal attack patterns
• Restrict access to the WordPress admin and plugin directories using IP-based access controls
