CVE-2025-27224 is a critical vulnerability affecting TRUfusion Enterprise versions through 7.10.4.0. The issue lies in the /trufusionPortal/fileupload endpoint, which inadequately sanitizes user-supplied input, allowing path traversal sequences (e.g., ../) to be included in file upload requests. This flaw enables attackers to write files to arbitrary locations on the server's filesystem, bypassing intended directory restrictions. By placing malicious files in strategic locations, attackers can execute arbitrary code, compromising the server's confidentiality, integrity, and availability. The vulnerability requires no authentication or user interaction, making it highly exploitable remotely over the network. The CVSS v3.1 base score of 9.8 reflects the ease of exploitation and severe impact. Although no public exploits are known yet, the vulnerability is classified under CWE-20 (Improper Input Validation), a common and dangerous weakness. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls. TRUfusion Enterprise is typically used in enterprise environments, often handling sensitive data and critical workflows, which elevates the risk posed by this vulnerability.

For European organizations, exploitation of this vulnerability could lead to full system compromise of TRUfusion Enterprise servers, resulting in unauthorized data access, data manipulation, service disruption, and potential lateral movement within networks. Given the critical nature of the flaw and the absence of authentication requirements, attackers can remotely execute arbitrary code, potentially deploying ransomware, stealing sensitive information, or disrupting business operations. Organizations in sectors such as finance, healthcare, manufacturing, and government that rely on TRUfusion Enterprise for operational processes are particularly at risk. The impact extends beyond individual organizations, as compromised systems could be leveraged to attack supply chains or critical infrastructure. The high CVSS score indicates a severe threat to confidentiality, integrity, and availability, with potential regulatory and reputational consequences under European data protection laws like GDPR.

1. Immediately restrict network access to the /trufusionPortal/fileupload endpoint using firewalls or web application firewalls (WAFs) to limit exposure to trusted IP addresses only. 2. Implement strict input validation and sanitization on the server side to detect and block path traversal sequences before file processing. 3. Monitor server logs and file system changes for unusual file uploads or modifications outside expected directories. 4. Deploy intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting this endpoint. 5. If possible, isolate TRUfusion Enterprise servers in segmented network zones to limit lateral movement in case of compromise. 6. Engage with the vendor for patches or official mitigations and apply them as soon as they become available. 7. Conduct a thorough security review and penetration testing of the affected systems to identify any signs of compromise. 8. Educate IT and security teams about this vulnerability and ensure incident response plans include scenarios involving arbitrary code execution via file upload endpoints.
