CVE-2025-5058: Store Manager For WooCommerce RCE Flaw

CVE-2025-5058 Overview

CVE-2025-5058 is a critical arbitrary file upload vulnerability affecting the eMagicOne Store Manager for WooCommerce plugin for WordPress. The vulnerability exists due to missing file type validation in the set_image() function in all versions up to and including 1.2.5. This security flaw allows unauthenticated attackers to upload arbitrary files on the affected site's server, potentially enabling remote code execution (RCE).

The vulnerability is particularly dangerous in default configurations where the default password remains set to 1:1, or in scenarios where an attacker has obtained valid credentials through other means. WordPress sites running vulnerable versions of this WooCommerce management plugin are at significant risk of complete server compromise.

Critical Impact

Unauthenticated attackers can upload malicious files including PHP webshells, enabling full remote code execution and complete site takeover on WordPress installations using vulnerable plugin versions.

Affected Products

• eMagicOne Store Manager for WooCommerce versions up to and including 1.2.5
• WordPress installations with the Store Manager Connector plugin
• WooCommerce stores using eMagicOne management tools

Technical Details for CVE-2025-5058

Vulnerability Analysis

This vulnerability is classified as CWE-434 (Unrestricted Upload of File with Dangerous Type), a severe weakness that allows attackers to bypass normal security controls by uploading executable content to the server. The attack can be executed remotely over the network without requiring user interaction or prior authentication, making it highly exploitable.

The vulnerable set_image() function fails to implement proper file type validation, accepting any file extension without restriction. When combined with the weak default authentication credentials (1:1), unauthenticated attackers can leverage this function to upload arbitrary files including PHP webshells or other malicious scripts. Once uploaded, these files can be executed directly on the server, granting the attacker full control over the WordPress installation and potentially the underlying server infrastructure.

Root Cause

The root cause of CVE-2025-5058 is insufficient input validation in the file upload handling mechanism. The set_image() function within the class-emosmconnectorcommon.php and class-emosmcwoocommerceoverrider.php classes does not verify that uploaded files conform to expected image types. This missing validation allows any file type to be uploaded and stored on the server, regardless of its actual content or extension.

Additionally, the plugin ships with weak default credentials (1:1 for username and password), which significantly lowers the barrier for exploitation. Administrators who do not change these default credentials leave their sites immediately vulnerable to unauthenticated attacks.

Attack Vector

The attack is network-based and follows this exploitation pattern:

1. The attacker identifies a WordPress site running a vulnerable version of eMagicOne Store Manager for WooCommerce
2. Using default credentials (1:1) or previously compromised credentials, the attacker authenticates to the plugin's connector interface
3. The attacker crafts a malicious request targeting the set_image() function with an arbitrary file payload (e.g., PHP webshell)
4. Due to missing file type validation, the server accepts and stores the malicious file
5. The attacker accesses the uploaded file directly via its URL, triggering code execution and gaining control of the server

The vulnerability is documented in the WordPress Plugin Trac and additional technical analysis is available from Ryan Kozak's security research. A proof-of-concept has been published in the GitHub PoC Repository.

Detection Methods for CVE-2025-5058

Indicators of Compromise

• Unexpected PHP files or other executable scripts appearing in WordPress upload directories
• Unusual web server access logs showing requests to the Store Manager connector endpoints with file upload payloads
• Authentication attempts using default credentials (1:1) against the plugin connector
• Newly created or modified files with suspicious extensions (.php, .phtml, .phar) in media directories

Detection Strategies

• Monitor file system changes in WordPress installations, particularly in /wp-content/uploads/ and plugin directories
• Implement web application firewall (WAF) rules to detect and block file upload attempts with executable extensions
• Audit authentication logs for access using default or common credentials against Store Manager endpoints
• Deploy endpoint detection solutions capable of identifying webshell behaviors and suspicious PHP execution patterns

Monitoring Recommendations

• Enable file integrity monitoring on WordPress installations to detect unauthorized file additions
• Configure alerting for new files created with executable extensions in web-accessible directories
• Review server access logs for POST requests to Store Manager connector endpoints containing binary or PHP content
• Implement real-time threat detection using SentinelOne's behavioral AI to identify malicious file uploads and subsequent execution

How to Mitigate CVE-2025-5058

Immediate Actions Required

• Immediately change default credentials (1:1) to strong, unique passwords if the plugin must remain active
• Update eMagicOne Store Manager for WooCommerce to the latest patched version as soon as available
• Conduct a full security audit of the WordPress uploads directory for any suspicious or unexpected files
• Temporarily disable the Store Manager Connector plugin until a patch is applied if credential security cannot be immediately verified

Patch Information

Organizations should monitor the Wordfence Vulnerability Report and the official WordPress plugin repository for updates to eMagicOne Store Manager for WooCommerce. Upgrade to versions newer than 1.2.5 once a security patch becomes available. Verify that the updated version includes proper file type validation in the set_image() function.

Workarounds

• Restrict network access to the Store Manager connector endpoints using .htaccess rules or server-level firewall configurations
• Implement server-side file upload restrictions to block executable file types in WordPress upload directories
• Deploy a web application firewall (WAF) with rules to validate file uploads and block dangerous content types
• If the plugin is not actively required, deactivate and remove it entirely from the WordPress installation

# Example .htaccess restriction for Store Manager connector
# Add to WordPress root .htaccess to restrict connector access by IP
<Files "class-emosmconnectorcommon.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.100
</Files>

# Block PHP execution in uploads directory
<Directory "/var/www/html/wp-content/uploads">
    <FilesMatch "\.php$">
        Order Deny,Allow
        Deny from all
    </FilesMatch>
</Directory>
