CVE-2025-14997: BuddyPress Path Traversal Vulnerability

CVE-2025-14997 Overview

The BuddyPress Xprofile Custom Field Types plugin for WordPress contains an arbitrary file deletion vulnerability due to insufficient file path validation in the delete_field function. This vulnerability affects all versions up to and including 1.2.8 and allows authenticated attackers with Subscriber-level access or higher to delete arbitrary files on the server. When critical files such as wp-config.php are deleted, this can lead to remote code execution and complete site compromise.

Critical Impact

Authenticated attackers can delete arbitrary files on the server, potentially leading to remote code execution when critical WordPress configuration files are removed.

Affected Products

• BuddyPress Xprofile Custom Field Types plugin for WordPress versions up to and including 1.2.8
• WordPress installations using the vulnerable plugin with BuddyPress extended profiles
• Web servers hosting affected WordPress installations

Technical Details for CVE-2025-14997

Vulnerability Analysis

This vulnerability is classified under CWE-22 (Path Traversal), which occurs when software uses external input to construct a pathname intended to identify a file or directory within a restricted parent directory, but fails to properly neutralize special elements that can cause the pathname to resolve outside of that directory.

The vulnerability exists in the delete_field function within the class-field-upload-helper.php file. The plugin fails to properly validate and sanitize file paths before performing deletion operations, allowing attackers to traverse directories and delete files outside the intended upload directory.

Root Cause

The root cause of this vulnerability is insufficient file path validation in the field deletion handler. The delete_field function accepts user-controlled input for file paths without adequately sanitizing path traversal sequences such as ../ or validating that the target file resides within the expected directory structure. This allows attackers to manipulate the file path parameter to target arbitrary files on the server filesystem.

Attack Vector

The attack is network-accessible and requires authenticated access with at least Subscriber-level privileges. An attacker must first obtain valid WordPress credentials with minimal permissions. Once authenticated, they can exploit the vulnerable delete_field function by crafting malicious requests containing path traversal sequences.

The attack typically involves manipulating the file path parameter to point to critical WordPress files such as wp-config.php. When this configuration file is deleted, WordPress enters a reinstallation state, potentially allowing the attacker to reconfigure the site with their own database credentials and achieve remote code execution.

The vulnerability requires no user interaction and can be exploited directly through crafted HTTP requests to the WordPress admin-ajax or REST API endpoints that handle field deletion operations. For detailed technical implementation, refer to the WordPress Plugin Source Code and the Wordfence Vulnerability Report.

Detection Methods for CVE-2025-14997

Indicators of Compromise

• Unexpected deletion of critical WordPress files such as wp-config.php, .htaccess, or core plugin files
• Web server logs showing requests to admin-ajax.php or REST API endpoints with path traversal patterns (../, ..%2f, %2e%2e/)
• WordPress installation prompts appearing unexpectedly indicating missing configuration files
• Error logs showing file-not-found errors for previously existing WordPress core files

Detection Strategies

• Monitor WordPress file integrity using security plugins or server-side file integrity monitoring (FIM) solutions
• Implement web application firewall (WAF) rules to detect and block path traversal patterns in request parameters
• Review web server access logs for suspicious patterns targeting the BuddyPress Xprofile plugin endpoints
• Enable WordPress audit logging to track file deletion operations and identify anomalous activity

Monitoring Recommendations

• Configure real-time alerts for deletion of critical WordPress configuration files
• Implement file system monitoring for the WordPress installation directory with focus on core files
• Set up log analysis rules to detect path traversal attempts in HTTP request parameters
• Regularly audit user accounts with Subscriber-level or higher access for unauthorized accounts

How to Mitigate CVE-2025-14997

Immediate Actions Required

• Update the BuddyPress Xprofile Custom Field Types plugin to the latest patched version immediately
• Review recent file deletion activity on the WordPress server for signs of exploitation
• Audit WordPress user accounts and remove any unauthorized or suspicious Subscriber-level accounts
• Implement additional authentication controls to limit access to sensitive plugin functionality

Patch Information

The vulnerability has been addressed in a security update released by the plugin developers. The fix can be reviewed in the WordPress Plugin Changeset. Administrators should update to a version newer than 1.2.8 through the WordPress plugin update mechanism or by downloading the latest version from the official WordPress plugin repository.

Workarounds

• Temporarily disable the BuddyPress Xprofile Custom Field Types plugin until patching is possible
• Restrict user registration and limit Subscriber-level account creation to reduce attack surface
• Implement server-level file system permissions to protect critical WordPress files from deletion
• Deploy a web application firewall with rules to block path traversal patterns in plugin requests

# Configuration example - Restrict write permissions on critical files
chmod 444 wp-config.php
chmod 444 .htaccess

# Enable mod_security rule to block path traversal attempts
# Add to Apache configuration or .htaccess
SecRule REQUEST_URI|ARGS|ARGS_NAMES "@rx (\.\./|\.\.\\|%2e%2e%2f|%2e%2e/|\.\.%2f|%2e%2e\\)" \
    "id:1001,phase:2,deny,status:403,msg:'Path Traversal Attempt Blocked'"
