FUXA Vulnerable to Pre-auth RCE via Path Manipulation & Configuration Injection

Pre-auth RCE in FUXA via Logic Bypass Summary A Critical vulnerability chain exists in FUXA (v.1.3.0-2706) that allows an unauthenticated remote attacker to achieve Full Remote Code Execution (RCE) as root. The exploit succeeds even when the platform is configured in its most secure state (Secure Mode Enabled and Node-RED Secure Auth Enabled). Details The vulnerability is a Path Confusion flaw in the authentication middleware. The server uses a substring …

FUXA has a hardcoded fallback JWT signing secret

FUXA used a static fallback JWT signing secret (frangoteam751) when no secretCode was configured. If authentication was enabled without explicitly setting a custom secret, an attacker who knew the default value could forge valid JWT tokens and bypass authentication. This issue has been addressed in version 1.3.0 by removing the static fallback and generating a secure random secret when no secretCode is provided.

FUXA has JWT Authentication Bypass via HTTP Referer header spoofing

FUXA 1.2.8 and prior contains an Authentication Bypass vulnerability leading to Remote Code Execution (RCE). The vulnerability exists in the server/api/jwt-helper.js middleware, which improperly trusts the HTTP "Referer" header to validate internal requests. A remote unauthenticated attacker can bypass JWT authentication by spoofing the Referer header to match the server's host. Successful exploitation allows the attacker to access the protected /api/runscript endpoint and execute arbitrary Node.js code on the server.

Server-Side Request Forgery (SSRF)

A Server-Side Request Forgery (SSRF) attack in FUXA 1.1.3 can be carried out leading to the obtaining of sensitive information from the server's internal environment and services, often potentially leading to the attacker executing commands on the server.
