CVE-2025-47687: StoreKeeper WooCommerce RCE Vulnerability

CVE-2025-47687 Overview

CVE-2025-47687 is a critical Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) affecting the StoreKeeper for WooCommerce WordPress plugin. This vulnerability allows unauthenticated attackers to upload malicious files, including web shells, directly to the web server. The flaw exists in versions through 14.4.4 of the plugin and can be exploited remotely over the network without any user interaction or authentication.

Critical Impact

This vulnerability enables attackers to upload web shells and achieve complete server compromise, potentially leading to full site takeover, data theft, and lateral movement within the hosting environment.

Affected Products

• StoreKeeper for WooCommerce plugin versions up to and including 14.4.4
• WordPress installations running the vulnerable StoreKeeper for WooCommerce plugin
• WooCommerce e-commerce sites utilizing StoreKeeper integration

Technical Details for CVE-2025-47687

Vulnerability Analysis

This vulnerability stems from improper file upload validation in the StoreKeeper for WooCommerce plugin. The plugin fails to properly restrict the types of files that can be uploaded to the server, allowing attackers to bypass security controls and upload executable files with dangerous extensions such as .php. Once uploaded, these malicious files can be accessed directly via HTTP requests, enabling remote code execution on the underlying server.

The attack requires no authentication or user interaction, making it particularly dangerous for publicly accessible WordPress installations. A successful exploit grants attackers the ability to execute arbitrary code with the privileges of the web server process, typically leading to complete site compromise.

Root Cause

The root cause of CVE-2025-47687 is the absence of proper server-side file type validation and sanitization in the file upload functionality. The plugin does not adequately verify that uploaded files conform to expected safe file types, nor does it implement proper filename sanitization to prevent uploading of files with executable extensions. This allows attackers to circumvent any client-side restrictions and upload arbitrary dangerous file types directly to the web server.

Attack Vector

The vulnerability is exploitable over the network by unauthenticated attackers. The attack flow typically involves:

1. An attacker identifies a WordPress site running a vulnerable version of StoreKeeper for WooCommerce
2. The attacker crafts a malicious HTTP request containing a web shell payload disguised or embedded within an upload request
3. Due to insufficient file type validation, the malicious file is accepted and stored on the server
4. The attacker accesses the uploaded web shell via its URL path, gaining remote code execution capabilities
5. With code execution achieved, the attacker can exfiltrate data, modify content, pivot to other systems, or establish persistent access

The vulnerability allows attackers to upload PHP web shells that provide interactive command execution capabilities on the compromised server. For detailed technical information, refer to the Patchstack Vulnerability Advisory.

Detection Methods for CVE-2025-47687

Indicators of Compromise

• Presence of unexpected .php files in WordPress upload directories, particularly wp-content/uploads/
• Web shells or suspicious files with names containing random strings or common web shell signatures
• Unusual HTTP POST requests to plugin endpoints with file upload payloads
• Unexpected processes spawned by the web server user (e.g., www-data or apache)

Detection Strategies

• Monitor file system changes in WordPress directories for newly created executable files
• Implement Web Application Firewall (WAF) rules to detect and block malicious file upload attempts
• Review web server access logs for suspicious POST requests targeting StoreKeeper plugin endpoints
• Scan WordPress installations for known web shell signatures and malicious file patterns

Monitoring Recommendations

• Enable real-time file integrity monitoring on WordPress installations
• Configure alerts for any new PHP file creation within the wp-content/ directory tree
• Monitor outbound connections from the web server for potential command-and-control traffic
• Implement centralized logging and SIEM integration for WordPress access and error logs

How to Mitigate CVE-2025-47687

Immediate Actions Required

• Update StoreKeeper for WooCommerce to the latest patched version immediately
• Audit the wp-content/uploads/ directory and all plugin directories for suspicious or unexpected PHP files
• Temporarily disable the StoreKeeper for WooCommerce plugin if an immediate update is not possible
• Review web server logs for signs of exploitation and investigate any suspicious upload activity

Patch Information

Organizations running StoreKeeper for WooCommerce should update to a patched version beyond 14.4.4. Consult the Patchstack Vulnerability Advisory for the latest remediation guidance and version information from the vendor.

Workarounds

• Implement strict file upload restrictions at the web server level to block executable file types
• Use a Web Application Firewall (WAF) to filter malicious upload requests
• Restrict write permissions on the wp-content/uploads/ directory to prevent PHP execution
• Consider network-level controls to limit access to WordPress admin and upload endpoints

# Apache configuration to prevent PHP execution in uploads directory
<Directory "/var/www/html/wp-content/uploads">
    <FilesMatch "\.php$">
        Require all denied
    </FilesMatch>
</Directory>

# Nginx configuration to prevent PHP execution in uploads directory
location ~* /wp-content/uploads/.*\.php$ {
    deny all;
}
