When a client request to a cluster node was replicated to other nodes in the cluster for verification, the Content-Length was forwarded. On a DELETE request, the body was ignored, but if the initial request had a Content-Length value other than 0, the receiving nodes would wait for the body and eventually timeout. Mitigation: The fix to check DELETE requests and overwrite non-zero Content-Length header values was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release. Cuando una petición de cliente a un nodo del clúster se replicó a otros nodos en el clúster para verificarlos, se redireccionó el Content-Length. • https://nifi.apache.org/security.html#CVE-2018-17194 • CWE-20: Improper Input Validation •

The template upload API endpoint accepted requests from different domain when sent in conjunction with ARP spoofing + man in the middle (MiTM) attack, resulting in a CSRF attack. The required attack vector is complex, requiring a scenario with client certificate authentication, same subnet access, and injecting malicious code into an unprotected (plaintext HTTP) website which the targeted user later visits, but the possible damage warranted a Severe severity level. Mitigation: The fix to apply Cross-Origin Resource Sharing (CORS) policy request filtering was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release. El endpoint de la API de subida de plantillas aceptaba peticiones de diferentes dominios al enviarse junto con un ataque de suplantación de ARP y otro Man-in-the-Middle (MitM), lo que resulta en un ataque Cross-Site Request Forgery (CSRF). • https://nifi.apache.org/security.html#CVE-2018-17195 • CWE-319: Cleartext Transmission of Sensitive Information CWE-863: Incorrect Authorization •

Any authenticated user (valid client certificate but without ACL permissions) could upload a template which contained malicious code and caused a denial of service via Java deserialization attack. The fix to properly handle Java deserialization was applied on the Apache NiFi 1.4.0 release. Users running a prior 1.x release should upgrade to the appropriate release. Cualquier usuario autenticado (certificado de cliente válido pero sin permisos de listas de control de acceso) podía cargar una plantilla que contenga código malicioso y provocar una denegación de servicio (DoS) mediante un ataque de deserialización de Java. La solución para manejar la deserialización de Java se aplicó en la distribución 1.4.0 de Apache NiFi. • https://nifi.apache.org/security.html#CVE-2017-15703 • CWE-502: Deserialization of Untrusted Data •
