What versions of Elasticsearch are vulnerable to remote code execution?
Elasticsearch versions from 1.0.0 to 1.6.0 are vulnerable to a directory traversal attack. Users should upgrade to 1.6.1 or later, or constrain access to the snapshot API to trusted sources. Elasticsearch versions prior to 1.6.1 are vulnerable to an attack that can result in remote code execution.
Why do Elasticsearch connections need to remain open?
The coordinating nodes in the local cluster establish long-lived TCP connections with specific nodes in the remote cluster. Elasticsearch requires these connections to remain open, even if the connections are idle for an extended period.
How can I protect my ElasticSearch server from security threats?
Alternately, ensure that only trusted applications have access to the transport protocol port. All Elasticsearch versions from 1.0.0 to 1.5.2 are vulnerable to an attack that uses Elasticsearch to modify files read and executed by certain other applications. Users should upgrade to 1.6.0.
How do I access Elasticsearch remotely?

How do I connect to an Elasticsearch server?
There are two ways to connect to your Elasticsearch cluster: Through the RESTful API or through the Java transport client. Both ways use an endpoint URL that includes a port, such as https://ec47fc4d2c53414e1307e85726d4b9bb.us-east-1.aws.found.io:9243 .
How do you expose Elasticsearch?
You need to include network. host:0.0. 0.0 in your elasticsearch. yml file so that it listens on the non-loopback address and after that, if your app-server and ES are both in the same VPC, app-server will be able to connect to ES(provided if you exposed 9200 port in security group(in case of AWS).
Is it safe to expose Elasticsearch?
Whatever you do, never expose your cluster nodes to the web . This sounds obvious, but evidently this isn't done by all. Your cluster should never-ever be exposed to the public web .

Connect to remote clusters edit
Your local cluster uses the transport interface to establish communication with remote clusters. The coordinating nodes in the local cluster establish long-lived TCP connections with specific nodes in the remote cluster. Elasticsearch requires these connections to remain open, even if the connections are idle for an extended period.
Dynamically configure remote clusters edit
Use the cluster update settings API to dynamically configure remote settings on every node in the cluster. The following request adds three remote clusters: cluster_one, cluster_two, and cluster_three.
Statically configure remote clusters edit
If you specify settings in elasticsearch.yml, only the nodes with those settings can connect to the remote cluster and serve remote cluster requests.
How to secure Elasticsearch?
You need to secure access to your remote Elasticsearch instance with a username and password. We recommend securing your remote Elasticsearch instance with a security plugin that requires anyone connecting to it provides authentication credentials. Atlassian provides a free plugin called Buckler for this purpose. Bitbucket Server also supports authentication to Elasticsearch through other plugins that provide basic authentication, like Elastic's Shield plugin.
What file to add elasticsearch parameters?
Add these parameters to your elasticsearch.yml file
How to enable Buckler?
To enable the Buckler for basic HTTP authentication, you add these properties to the file, creating a username and password that Bitbucket will use to access Elasticsearch (configured in a later step).
What is elasticsearch.yml?
The elasticsearch.yml file contains configuration details for your Elasticsearch instance.
Where is the configuration directory in ElasticSearch?
The location of your configuration directory varies depending on how you installed Elasticsearch. For rpm/deb installations the location is typically in /etc/elasticsearch
Where is bitbucket.properties file?
Locate the bitbucket.properties file in the <Bitbucket home directory>/shared directory.
Does Bitbucket require Elasticsearch?

What is ElasticSearch Security 6.4.0?
Elasticsearch Security versions 6.4.0 to 6.4.2 contain an error in the way request headers are applied to requests when using the Active Directory, LDAP, Native, or File realms. A request may receive headers intended for another request if the same username is being authenticated concurrently; when used with run as, this can result in the request running as the incorrect user. This could allow a user to access information that they should not have access to.
What is the audit log in ElasticSearch?
The Elasticsearch audit log could contain sensitive information such as password hashes or authentication tokens. This could allow an Elasticsearch administrator to view these details.

In Logstash versions prior to 2.3.3, when using the Netflow Codec plugin, a remote attacker crafting malicious Netflow v5, Netflow v9 or IPFIX packets could perform a denial of service attack on the Logstash instance. The errors resulting from these crafted inputs are not handled by the codec and can cause the Logstash process to exit.

In Elasticsearch versions before 7.11.2 and 6.8.15 document disclosure flaw was found in the Elasticsearch suggester and profile API when Document and Field Level Security are enabled. The suggester and profile API are normally disabled for an index when document level security is enabled on the index. Certain queries are able to enable the profiler and suggester which could lead to disclosing the existence of documents and fields the attacker should not be able to view.
What is a sensitive data disclosure flaw?
