Directory Traversal in FUXA Allows Remote Code Execution

Publication date: 2026-02-09

Last updated on: 2026-02-13

Assigner: GitHub, Inc.

Description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.2.11, there is a flaw in the path sanitization logic allows an authenticated attacker with administrative privileges to bypass directory traversal protections. By using nested traversal sequences (e.g., ....//), an attacker can write arbitrary files to the server filesystem, including sensitive directories like runtime/scripts. This leads to Remote Code Execution (RCE) when the server reloads the malicious scripts. This vulnerability is fixed in 1.2.11.

CWE ID Description
CWE-23 The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory.
CWE-22 The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
CWE-184 The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.

Executive Summary

This vulnerability exists in FUXA, a web-based Process Visualization software, in versions prior to 1.2.11. It is caused by a flaw in the path sanitization logic that allows an authenticated attacker with administrative privileges to bypass directory traversal protections.

By using nested traversal sequences such as ....//, the attacker can write arbitrary files to the server's filesystem, including sensitive directories like runtime/scripts.

This can lead to Remote Code Execution (RCE) when the server reloads the malicious scripts that were written.

The vulnerability is fixed in version 1.2.11.

Impact Analysis

This vulnerability can have serious impacts because it allows an attacker with administrative access to write arbitrary files to the server, potentially including malicious scripts.

When the server reloads these malicious scripts, it can lead to Remote Code Execution (RCE), which means the attacker can execute arbitrary code on the server.

This could result in full compromise of the affected system, unauthorized access to sensitive data, disruption of services, or further attacks within the network.

Mitigation Strategies

To mitigate this vulnerability, upgrade FUXA to version 1.2.11 or later, where the path sanitization flaw has been fixed.

Ensure that only trusted administrators have access to the system, as the vulnerability requires authenticated administrative privileges.

Review and monitor the server filesystem, especially sensitive directories like runtime/scripts, for any unauthorized or suspicious file changes.
