CVE-2019-12421
https://notcve.org/view.php?id=CVE-2019-12421
When using an authentication mechanism other than PKI, when the user clicks Log Out in NiFi versions 1.0.0 to 1.9.2, NiFi invalidates the authentication token on the client side but not on the server side. This permits the user's client-side token to be used for up to 12 hours after logging out to make API requests to NiFi. Cuando se utiliza un mecanismo de autenticación diferente de PKI, al momento que el usuario hace clic en el Log Out en NiFi versiones 1.0.0 hasta 1.9.2, NiFi invalida el token de autenticación en el lado del cliente pero no en el lado del servidor. Esto permite que el token del lado del cliente del usuario sea usado hasta 12 horas después de cerrar sesión para llevar a cabo peticiones de la API a NiFi. • https://lists.apache.org/thread.html/rca37935d661f4689cb4119f1b3b224413b22be161b678e6e6ce0c69b%40%3Ccommits.nifi.apache.org%3E https://nifi.apache.org/security.html#CVE-2019-12421 • CWE-613: Insufficient Session Expiration •

https://notcve.org/view.php?id=CVE-2019-10080
The XMLFileLookupService in NiFi versions 1.3.0 to 1.9.2 allowed trusted users to inadvertently configure a potentially malicious XML file. The XML file has the ability to make external calls to services (via XXE) and reveal information such as the versions of Java, Jersey, and Apache that the NiFI instance uses. El XMLFileLookupService en NiFi versiones 1.3.0 hasta 1.9.2, permitió a usuarios confiables configurar inadvertidamente un archivo XML potencialmente malicioso. El archivo XML tiene la capacidad de realizar llamadas externas a los servicios (mediante XXE) y revelar información tal y como las versiones de Java, Jersey y Apache que utilizan la instancia de NiFi. • https://lists.apache.org/thread.html/rca37935d661f4689cb4119f1b3b224413b22be161b678e6e6ce0c69b%40%3Ccommits.nifi.apache.org%3E https://nifi.apache.org/security.html#CVE-2019-10080 https://www.oracle.com/security-alerts/cpuApr2021.html • CWE-611: Improper Restriction of XML External Entity Reference •
CVE-2019-10086 – apache-commons-beanutils: does not suppresses the class property in PropertyUtilsBean by default
https://notcve.org/view.php?id=CVE-2019-10086
In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean. En Apache Commons Beanutils 1.9.2, se agregó una clase especial BeanIntrospector que permite suprimir la capacidad de un atacante para acceder al cargador de clases a través de la propiedad de clase disponible en todos los objetos Java. Sin embargo, no se esta usando esta característica por defecto de PropertyUtilsBean. A flaw was found in the Apache Commons BeanUtils, where the class property in PropertyUtilsBean is not suppressed by default. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00007.html http://mail-archives.apache.org/mod_mbox/www-announce/201908.mbox/%3cC628798F-315D-4428-8CB1-4ED1ECC958E4%40apache.org%3e https://access.redhat.com/errata/RHSA-2019:4317 https://access.redhat.com/errata/RHSA-2020:0057 https://access.redhat.com/errata/RHSA-2020:0194 https://access.redhat.com/errata/RHSA-2020:0804 https://access.redhat.com/errata/RHSA-2020:0805 https://access.redhat.com/errata/RHSA-2020:0806 • CWE-502: Deserialization of Untrusted Data •
CVE-2018-17195
https://notcve.org/view.php?id=CVE-2018-17195
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 •
CVE-2018-17192
https://notcve.org/view.php?id=CVE-2018-17192
The X-Frame-Options headers were applied inconsistently on some HTTP responses, resulting in duplicate or missing security headers. Some browsers would interpret these results incorrectly, allowing clickjacking attacks. Mitigation: The fix to consistently apply the security headers was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release. Las cabeceras X-Frame-Options se aplicaron de forma inconsistente en algunas respuestas HTTP, lo que resulta en cabeceras de seguridad duplicadas o faltantes. • https://nifi.apache.org/security.html#CVE-2018-17192 • CWE-1021: Improper Restriction of Rendered UI Layers or Frames •
