Affected packages
elasticsearch < 1.4.0


VuXML ID 5951fb49-1ba2-11e5-b43d-002590263bf5
Discovery 2014-10-01

Elastic reports:

Vulnerability Summary: Elasticsearch versions 1.3.x and prior have a default configuration for CORS that allows an attacker to craft links that could cause a user's browser to send requests to Elasticsearch instances on their local network. These requests could cause data loss or compromise.

Remediation Summary: Users should either set "http.cors.enabled" to false, or set "http.cors.allow-origin" to the value of the server that should be allowed access, such as localhost or a server hosting Kibana. Disabling CORS entirely with the former setting is more secure, but may not be suitable for all use cases.
