Elasticsearch ESA-2018-07

critical Nessus Plugin ID 112044

Language:

Synopsis

The remote web server hosts a Java application that is affected by multiple vulnerabilities.

Description

X-Pack Security versions 6.2.0, 6.2.1, and 6.2.2 are vulnerable to a user impersonation attack via incorrect XML canonicalization and DOM traversal. An attacker might have been able to impersonate a legitimate user if the SAML Identity Provider allows for self registration with arbitrary identifiers and the attacker can register an account which an identifier that shares a suffix with a legitimate account. Both of those conditions must be true in order to exploit this flaw.

Solution

Users should upgrade to Elasticsearch version 6.2.3.
