Elasticsearch ESA-2018-16

medium Nessus Plugin ID 118799

Language:

Synopsis

The remote web server hosts a Java application that is vulnerable.

Description

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.

Solution

Users should upgrade to Elasticsearch version 6.4.3.If upgrading is not possible setting the realms cache.ttl option to 0 will prevent caching any user data. This will mitigate this issue but will slow requests considerably.
