CVE-2025-48148: StoreKeeper WooCommerce RCE Vulnerability

CVE-2025-48148 Overview

CVE-2025-48148 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) affecting StoreKeeper for WooCommerce, a WordPress plugin developed by StoreKeeper B.V. This vulnerability allows attackers to upload malicious files to vulnerable WordPress installations, potentially leading to complete site compromise through remote code execution.

The vulnerability exists in versions through 14.4.4 of the StoreKeeper for WooCommerce plugin. By exploiting improper file upload validation, unauthenticated attackers can upload arbitrary files including web shells and malicious scripts to the target server.

Critical Impact

This vulnerability allows unauthenticated remote attackers to upload malicious files to WordPress sites, potentially enabling complete server takeover with no user interaction required. The attack can propagate beyond the vulnerable component, affecting other hosted applications.

Affected Products

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

Technical Details for CVE-2025-48148

Vulnerability Analysis

This unrestricted file upload vulnerability stems from inadequate validation of uploaded file types within the StoreKeeper for WooCommerce plugin. The vulnerability allows attackers to bypass security controls and upload files with dangerous extensions such as .php, .phtml, or other executable formats to the WordPress server.

The network-based attack vector requires no authentication or user interaction, making it highly exploitable. When a malicious file is successfully uploaded and placed in an accessible directory, an attacker can execute arbitrary code on the server by directly requesting the uploaded file through a web browser.

The changed scope indicator means that successful exploitation can impact resources beyond the vulnerable component itself, potentially compromising other sites on shared hosting environments or accessing sensitive data from connected databases and services.

Root Cause

The root cause of CVE-2025-48148 is improper input validation in the file upload handling functionality of the StoreKeeper for WooCommerce plugin. The plugin fails to adequately verify the type, extension, and content of uploaded files, allowing attackers to upload executable files that should be restricted.

Specifically, the vulnerability likely stems from:

• Missing or insufficient file extension validation
• Lack of MIME type verification
• Absence of content-based file type checking
• Improper sanitization of uploaded file names

Attack Vector

The attack can be executed remotely over the network by any unauthenticated attacker. The exploitation process typically involves:

1. Identifying a WordPress site running the vulnerable StoreKeeper for WooCommerce plugin
2. Locating the vulnerable file upload endpoint
3. Crafting a malicious payload (e.g., PHP web shell) disguised or presented in a format that bypasses validation
4. Uploading the malicious file to the target server
5. Accessing the uploaded file directly via web request to execute arbitrary code

The vulnerability allows for arbitrary file upload without proper authorization checks. For detailed technical information, refer to the Patchstack security advisory.

Detection Methods for CVE-2025-48148

Indicators of Compromise

• Unexpected PHP or executable files appearing in WordPress upload directories or plugin folders
• Unusual file names with suspicious patterns in /wp-content/uploads/ or plugin directories
• Web server access logs showing direct requests to newly uploaded PHP files
• Outbound connections from the web server to unknown external hosts
• Modified or new files with recent timestamps in plugin directories

Detection Strategies

• Monitor file system changes in WordPress installation directories, particularly within the wp-content folder
• Implement Web Application Firewall (WAF) rules to detect and block suspicious file upload attempts
• Review web server access logs for POST requests to plugin endpoints followed by GET requests to unusual file paths
• Deploy file integrity monitoring solutions to detect unauthorized file additions
• Scan for known web shell signatures and suspicious PHP code patterns

Monitoring Recommendations

• Enable detailed logging for file upload operations on WordPress installations
• Configure alerts for new executable files created in web-accessible directories
• Implement real-time monitoring for outbound connections from web server processes
• Monitor for unusual process execution originating from web server user accounts
• Set up periodic scans for known malicious file patterns and web shells

How to Mitigate CVE-2025-48148

Immediate Actions Required

• Update StoreKeeper for WooCommerce plugin to a patched version above 14.4.4 immediately
• Audit your WordPress installation for any suspicious files that may have been uploaded
• Review web server access logs for evidence of exploitation attempts
• Temporarily disable the StoreKeeper for WooCommerce plugin if an update is not immediately available
• Implement WAF rules to block suspicious file upload requests targeting the plugin

Patch Information

Users should update the StoreKeeper for WooCommerce plugin to the latest available version through the WordPress admin dashboard or by downloading from the official WordPress plugin repository. For additional vulnerability details and remediation guidance, consult the Patchstack advisory.

Workarounds

• Disable the StoreKeeper for WooCommerce plugin until a patch is applied
• Implement server-level restrictions on executable file uploads in WordPress directories
• Configure web server rules to prevent direct execution of PHP files in upload directories
• Use a Web Application Firewall to filter malicious file upload attempts
• Restrict network access to WordPress admin and plugin endpoints to trusted IP addresses

# Apache configuration to prevent PHP execution in uploads directory
# Add to .htaccess in wp-content/uploads/
<FilesMatch "\.(?:php|phtml|php3|php4|php5|phps)$">
    Require all denied
</FilesMatch>

# Alternative: Disable PHP execution entirely in uploads
