Executive brief
FUXA is a web-based industrial process control and visualization platform (SCADA/HMI) used to monitor and manage manufacturing and infrastructure systems. A critical vulnerability in its project import feature allows attackers to execute arbitrary code on the server hosting FUXA, leading to complete system takeover, data theft, and disruption of critical industrial operations. An attacker with network access can upload a malicious project file without authentication to compromise the entire system.
Technical details
FUXA v1.2.7 suffers from improper input validation and insufficient code sandboxing in the project import endpoint. The vulnerability is rooted in unsanitized script execution within imported project files (CWE-78: OS Command Injection and CWE-94: Code Injection). The project import functionality accepts user-supplied files and executes embedded scripts without proper validation or sandboxing. The attack requires only network access to the FUXA instance and no prior authentication, as evidenced by the CVSS v3.1 vector showing PR:N (no privileges required) and UI:N (no user interaction). An attacker can craft a malicious project file containing arbitrary shell commands or code that executes with the privileges of the FUXA process, resulting in remote code execution. Patches are expected to be available; verify the fuxa-server package version and upgrade beyond v1.2.7.
