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 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.
FUXA <= 1.1.12 has a Local File Inclusion vulnerability via file=fuxa.log
A remote command execution (RCE) vulnerability in the /api/runscript endpoint of FUXA 1.1.13 allows attackers to execute arbitrary commands via a crafted POST request.
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.
