CVE-2025-27224 identifies a critical path traversal vulnerability in TRUfusion Enterprise versions through 7.10.4.0. The vulnerability exists in the /trufusionPortal/fileupload endpoint, which is designed to handle file uploads. Due to insufficient input sanitization, attackers can include path traversal sequences (e.g., ../) in the filename parameter, enabling them to write files outside the intended upload directory. This arbitrary file write capability allows attackers to place malicious files anywhere on the local server's filesystem, including locations that could lead to execution of arbitrary code. The lack of proper validation means that an attacker can potentially overwrite system files, upload web shells, or implant malware, resulting in full system compromise. Exploitation does not require authentication or user interaction, increasing the attack surface and risk. Although no known exploits are currently reported in the wild, the vulnerability’s characteristics make it a high-value target for attackers. The absence of a CVSS score suggests that the vulnerability is newly disclosed, requiring organizations to assess and prioritize remediation. The vulnerability affects all installations of TRUfusion Enterprise up to version 7.10.4.0, though exact affected versions are not specified. The threat is significant due to the potential for complete loss of confidentiality, integrity, and availability of affected systems.

For European organizations, this vulnerability could lead to severe consequences including unauthorized access, data breaches, and disruption of critical enterprise services. Organizations relying on TRUfusion Enterprise for operational workflows, especially in sectors such as finance, manufacturing, healthcare, and government, face risks of system compromise and data theft. Attackers exploiting this flaw could gain persistent footholds, escalate privileges, and move laterally within networks, potentially impacting sensitive information and operational continuity. The ability to execute arbitrary code on servers could also facilitate ransomware deployment or espionage activities. Given the endpoint’s exposure and lack of authentication requirements, the attack vector is broad, increasing the likelihood of exploitation. The impact extends beyond individual organizations to supply chains and partners interconnected with affected entities. European data protection regulations (e.g., GDPR) impose strict requirements on breach notification and data security, increasing legal and financial risks for affected organizations.

Immediate mitigation steps include implementing strict input validation and sanitization on the /trufusionPortal/fileupload endpoint to reject any path traversal sequences or unexpected characters in file names. Organizations should restrict file system permissions for the application process to limit write access only to necessary directories, preventing arbitrary file placement. Network segmentation and application-layer firewalls can reduce exposure of the vulnerable endpoint. Monitoring and logging file upload activities can help detect suspicious behavior early. Until an official patch is released, consider disabling or restricting access to the file upload functionality if feasible. Conduct thorough security audits and penetration testing focused on file upload mechanisms. Deploy endpoint detection and response (EDR) solutions to identify potential exploitation attempts. Finally, maintain an incident response plan tailored to handle potential exploitation scenarios involving arbitrary code execution.
