CVE-2018-17244 (CCN-154548)

Assigned:2018-11-06
Published:2018-11-06
Updated:2019-10-09
Summary: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.
