CVE-2025-30933: LogisticsHub File Upload RCE Vulnerability

CVE-2025-30933 Overview

CVE-2025-30933 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) affecting the LiquidThemes LogisticsHub WordPress theme. This vulnerability allows unauthenticated attackers to upload malicious files, including web shells, directly to the web server. The flaw exists in versions from n/a through 1.1.6 of the LogisticsHub theme, enabling complete server compromise through arbitrary file upload functionality.

Critical Impact

Unauthenticated remote attackers can upload web shells to gain persistent backdoor access, execute arbitrary commands, and fully compromise affected WordPress installations and their underlying servers.

Affected Products

• LiquidThemes LogisticsHub WordPress Theme versions through 1.1.6
• WordPress installations using the vulnerable LogisticsHub theme
• Web servers hosting affected WordPress sites

Technical Details for CVE-2025-30933

Vulnerability Analysis

This vulnerability stems from insufficient validation of uploaded file types within the LogisticsHub WordPress theme. The affected component fails to properly verify that uploaded files are safe before allowing them to be stored on the web server. Without proper file type restrictions, content validation, or execution prevention controls, attackers can bypass intended security measures and upload executable scripts.

The vulnerability is network-accessible and requires no authentication or user interaction to exploit, making it particularly dangerous for internet-facing WordPress installations. Successful exploitation can result in complete compromise of confidentiality, integrity, and availability of the affected system, with potential to impact other resources beyond the vulnerable application itself.

Root Cause

The root cause is an Unrestricted Upload of File with Dangerous Type (CWE-434). The LogisticsHub theme does not adequately validate or sanitize file uploads, allowing attackers to upload files with dangerous extensions such as .php, .phtml, or other executable file types. The application likely relies on client-side validation or insufficient server-side checks that can be easily bypassed.

Attack Vector

The attack is conducted over the network against the file upload functionality exposed by the LogisticsHub theme. An attacker identifies an upload endpoint within the theme, crafts a malicious request containing a web shell payload (typically a PHP file), and submits it to the server. Due to missing or inadequate file type validation, the server accepts and stores the malicious file in a web-accessible location.

Once uploaded, the attacker can access the web shell through a direct HTTP request, gaining the ability to execute arbitrary commands on the server with the privileges of the web server process. This typically leads to full server compromise, data exfiltration, lateral movement within the network, and establishment of persistent backdoor access.

Detection Methods for CVE-2025-30933

Indicators of Compromise

• Unexpected PHP files or scripts appearing in WordPress theme directories, particularly under wp-content/themes/logistics-hub/
• Web server access logs showing requests to unfamiliar .php files within the LogisticsHub theme directory
• Suspicious POST requests to theme upload endpoints containing encoded or obfuscated payloads
• Evidence of command execution or outbound connections originating from the web server process

Detection Strategies

• Monitor file system changes within WordPress installation directories, especially new executable files
• Implement Web Application Firewall (WAF) rules to detect and block web shell upload attempts
• Review web server access logs for anomalous requests to PHP files that were recently created
• Use file integrity monitoring to alert on new or modified files in theme directories

Monitoring Recommendations

• Enable detailed logging for all HTTP POST requests to WordPress upload handlers
• Implement real-time alerting for new PHP files created within the web root
• Monitor for suspicious process spawning from the web server process (e.g., www-data spawning shell commands)
• Conduct regular scans for known web shell signatures and behaviors

How to Mitigate CVE-2025-30933

Immediate Actions Required

• Identify and audit all WordPress installations using the LogisticsHub theme version 1.1.6 or earlier
• Disable or remove the LogisticsHub theme until a patched version is available
• Scan existing installations for signs of compromise, including unauthorized PHP files
• Implement Web Application Firewall rules to block file upload attempts to vulnerable endpoints

Patch Information

Review the Patchstack WordPress Vulnerability Report for the latest information on available patches and remediation guidance from LiquidThemes. Monitor the theme vendor's official channels for security updates.

Workarounds

• Temporarily disable file upload functionality within the LogisticsHub theme by removing or restricting access to vulnerable endpoints
• Implement server-level restrictions to prevent execution of PHP files in upload directories using .htaccess or web server configuration
• Use a Web Application Firewall to filter and block malicious file upload requests
• Restrict file upload directory permissions and ensure uploaded files cannot be executed

# Apache .htaccess configuration to prevent PHP execution in uploads directory
# Place this in the WordPress uploads directory
<FilesMatch "\.(?:php[1-7]?|phtml|phar)$">
    Require all denied
</FilesMatch>

# Alternative: Disable PHP processing entirely in the directory
