CVE-2025-27224: Trufusion Enterprise Path Traversal Flaw

CVE-2025-27224 Overview

CVE-2025-27224 is a critical path traversal vulnerability in Rocket Software TRUfusion Enterprise through version 7.10.4.0. The vulnerability exists in the /trufusionPortal/fileupload endpoint, which fails to properly sanitize user-supplied input. This allows attackers to include path traversal sequences in file upload requests, enabling arbitrary file writes to any location on the server with any filename and file type. Successful exploitation leads to remote code execution (RCE) without authentication.

Critical Impact

This pre-authentication vulnerability allows unauthenticated remote attackers to achieve arbitrary code execution on affected TRUfusion Enterprise servers by exploiting improper input validation in the file upload functionality.

Affected Products

• Rocket Software TRUfusion Enterprise through version 7.10.4.0
• All TRUfusion Enterprise deployments using the vulnerable /trufusionPortal/fileupload endpoint
• B2B supply chain integration systems utilizing TRUfusion Enterprise

Technical Details for CVE-2025-27224

Vulnerability Analysis

This vulnerability represents a classic path traversal attack combined with unrestricted file upload, resulting in remote code execution capabilities. The /trufusionPortal/fileupload endpoint in TRUfusion Enterprise is designed to handle file uploads for the B2B supply chain integration platform. However, the application fails to implement proper input sanitization on the filename parameter, allowing attackers to escape the intended upload directory.

By including directory traversal sequences such as ../ in the filename parameter, an attacker can write files to arbitrary locations on the server's file system. This becomes particularly dangerous because the application does not restrict the file type that can be uploaded, meaning an attacker can upload executable files, web shells, or configuration files to sensitive locations.

The pre-authentication nature of this vulnerability significantly increases its severity, as no credentials are required to exploit it. An attacker with network access to the TRUfusion Enterprise portal can achieve complete system compromise.

Root Cause

The root cause of CVE-2025-27224 is improper input validation (CWE-20) in the file upload handler. The application directly uses user-supplied filename input without sanitizing or validating path components. Specifically, the endpoint fails to:

1. Strip or reject path traversal sequences (../, ..\\)
2. Validate that the resulting file path remains within the intended upload directory
3. Restrict allowed file extensions or MIME types
4. Implement proper canonicalization of file paths before file system operations

Attack Vector

The attack vector for this vulnerability is network-based and requires no authentication or user interaction. An attacker can craft a malicious HTTP request to the /trufusionPortal/fileupload endpoint containing:

1. Path traversal sequences in the filename parameter to navigate to a target directory
2. Malicious content in the file body (e.g., a web shell or executable)
3. An appropriate file extension for the malicious payload

The attacker sends a multipart form-data request with the crafted filename. For example, including ../../../../webapps/ROOT/shell.jsp as the filename would write a JSP web shell to the web application root, which could then be accessed directly via HTTP to execute arbitrary commands on the server.

Detection Methods for CVE-2025-27224

Indicators of Compromise

• Unexpected files appearing in web application directories, especially executable files like .jsp, .war, .sh, or .exe
• HTTP requests to /trufusionPortal/fileupload containing path traversal sequences (../) in filenames
• New or modified files in system directories such as /etc/, /var/www/, or application deployment directories
• Web shells or backdoor files in the TRUfusion Enterprise installation directory

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block path traversal patterns (../, ..%2f, ..%5c) in file upload requests
• Monitor HTTP access logs for requests to /trufusionPortal/fileupload with suspicious filename parameters
• Deploy file integrity monitoring (FIM) on critical directories to detect unauthorized file creation or modification
• Use network intrusion detection systems (NIDS) with signatures for path traversal attacks targeting file upload endpoints

Monitoring Recommendations

• Enable detailed logging on the TRUfusion Enterprise application to capture all file upload requests with full parameter details
• Configure alerts for any file creation events outside the designated upload directory
• Monitor for execution of newly created files in web-accessible directories
• Implement anomaly detection for unusual file types being uploaded to the application

How to Mitigate CVE-2025-27224

Immediate Actions Required

• Restrict network access to the TRUfusion Enterprise portal to trusted IP addresses only using firewall rules
• Deploy a web application firewall (WAF) with rules to block path traversal sequences in all HTTP parameters
• If possible, disable or remove the /trufusionPortal/fileupload endpoint until a patch can be applied
• Review file system permissions to ensure the application runs with minimal required privileges

Patch Information

Organizations should contact Rocket Software directly for patch availability and update instructions. Monitor the Rocket Software TRUfusion Enterprise product page for security advisories and updates.

Upgrade to a patched version of TRUfusion Enterprise when available. Ensure all instances are updated, including development and staging environments.

Workarounds

• Implement network segmentation to isolate TRUfusion Enterprise servers from untrusted networks
• Configure reverse proxy rules to sanitize and validate file upload requests before they reach the application
• Apply operating system-level file system controls to prevent writes outside designated directories
• Consider implementing application-level virtual patching through WAF rules while awaiting an official fix

# Example: Block path traversal patterns at the web server level (Apache)
# Add to httpd.conf or .htaccess for the TRUfusion portal
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./|\.\.\\) [NC,OR]
RewriteCond %{REQUEST_URI} (\.\./|\.\.\\) [NC]
RewriteRule .* - [F,L]

# Example: iptables rule to restrict access to TRUfusion Enterprise (adjust port as needed)
iptables -A INPUT -p tcp --dport 8080 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
