In Eclipse Jetty 9.4.6.v20170531 to 9.4.36.v20210114 (inclusive), 10.0.0, and 11.0.0 when Jetty handles a request containing multiple Accept headers with a large number of quality (i.e. q) parameters, the server may enter a denial of service (DoS) state due to high CPU usage processing those quality values, resulting in minutes of CPU time exhausted processing those quality values.

Resource Exhaustion

A flaw was found in jackson-databind before 2.9.10.7

CVE-2021-20190 8.1 - High - January 19, 2021

A flaw was found in jackson-databind before 2.9.10.7. FasterXML mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Marshaling, Unmarshaling

In Apache NiFi 1.10.0 to 1.11.4, the NiFi stateless execution engine produced log output which included sensitive property values

CVE-2020-9486 7.5 - High - October 01, 2020

In Apache NiFi 1.10.0 to 1.11.4, the NiFi stateless execution engine produced log output which included sensitive property values. When a flow was triggered, the flow definition configuration JSON was printed, potentially containing sensitive values in plaintext.

Insertion of Sensitive Information into Log File

In Apache NiFi 1.0.0 to 1.11.4

CVE-2020-9487 7.5 - High - October 01, 2020

In Apache NiFi 1.0.0 to 1.11.4, the NiFi download token (one-time password) mechanism used a fixed cache size and did not authenticate a request to create a download token, only when attempting to use the token to access the content. An unauthenticated user could repeatedly request download tokens, preventing legitimate users from requesting download tokens.

Missing Authentication for Critical Function

In Apache NiFi 1.2.0 to 1.11.4

CVE-2020-9491 7.5 - High - October 01, 2020

In Apache NiFi 1.2.0 to 1.11.4, the NiFi UI and API were protected by mandating TLS v1.2, as well as listening connections established by processors like ListenHTTP, HandleHttpRequest, etc. However intracluster communication such as cluster request replication, Site-to-Site, and load balanced queues continued to support TLS v1.0 or v1.1.

Inadequate Encryption Strength

In Apache NiFi 1.0.0 to 1.11.4, the notification service manager and various policy authorizer and user group provider objects

CVE-2020-13940 5.5 - Medium - October 01, 2020

In Apache NiFi 1.0.0 to 1.11.4, the notification service manager and various policy authorizer and user group provider objects allowed trusted administrators to inadvertently configure a potentially malicious XML file. The XML file has the ability to make external calls to services (via XXE).

XXE

In Apache NiFi 0.0.1 to 1.11.0, the flow fingerprint factory generated flow fingerprints

CVE-2020-1942 7.5 - High - February 11, 2020

In Apache NiFi 0.0.1 to 1.11.0, the flow fingerprint factory generated flow fingerprints which included sensitive property descriptor values. In the event a node attempted to join a cluster and the cluster flow was not inheritable, the flow fingerprint of both the cluster and local flow was printed, potentially containing sensitive values in plaintext.

Information Disclosure

An information disclosure vulnerability was found in Apache NiFi 1.10.0

CVE-2020-1928 5.3 - Medium - January 28, 2020

An information disclosure vulnerability was found in Apache NiFi 1.10.0. The sensitive parameter parser would log parsed values for debugging purposes. This would expose literal values entered in a sensitive property when no parameter was present.

Insertion of Sensitive Information into Log File

The XMLFileLookupService in NiFi versions 1.3.0 to 1.9.2 allowed trusted users to inadvertently configure a potentially malicious XML file

CVE-2019-10080 6.5 - Medium - November 19, 2019

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.

XXE

When updating a Process Group

CVE-2019-10083 5.3 - Medium - November 19, 2019

When updating a Process Group via the API in NiFi versions 1.3.0 to 1.9.2, the response to the request includes all of its contents (at the top most level, not recursively). The response included details about processors and controller services which the user may not have had read access to.

Information Disclosure

When using an authentication mechanism other than PKI

CVE-2019-12421 8.8 - High - November 19, 2019

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.

Insufficient Session Expiration

In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which

CVE-2019-10086 7.3 - High - August 20, 2019

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.

When a client request to a cluster node was replicated to other nodes in the cluster for verification, the Content-Length was forwarded

CVE-2018-17194 7.5 - High - December 19, 2018

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.

Improper Input Validation

The template upload API endpoint accepted requests

CVE-2018-17195 7.5 - High - December 19, 2018

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.

AuthZ

The message-page.jsp error page used the value of the HTTP request header X-ProxyContextPath without sanitization

CVE-2018-17193 6.1 - Medium - December 19, 2018

The message-page.jsp error page used the value of the HTTP request header X-ProxyContextPath without sanitization, resulting in a reflected XSS attack. Mitigation: The fix to correctly parse and sanitize the request attribute value was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release.

XSS

The X-Frame-Options headers were applied inconsistently on some HTTP responses, resulting in duplicate or missing security headers

CVE-2018-17192 6.5 - Medium - December 19, 2018

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.

Clickjacking

CVE-2018-1309 9.8 - Critical - May 23, 2018

Apache NiFi External XML Entity issue in SplitXML processor. Malicious XML content could cause information disclosure or remote code execution. The fix to disable external general entity parsing and disallow doctype declarations was applied on the Apache NiFi 1.6.0 release. Users running a prior 1.x release should upgrade to the appropriate release.

XXE

Apache NiFi JMS Deserialization issue because of ActiveMQ client vulnerability

CVE-2018-1310 7.5 - High - May 23, 2018

Apache NiFi JMS Deserialization issue because of ActiveMQ client vulnerability. Malicious JMS content could cause denial of service. See ActiveMQ CVE-2015-5254 announcement for more information.
