SynopsisThe remote web server hosts a Java application that is vulnerable.
DescriptionKibana versions 4.0 to 4.6, 5.0 to 5.6.12, and 6.0 to 6.4.2 contain an error in the way authorization credentials are used when generating PDF reports. If a report requests external resources plaintext credentials are included in the HTTP request that could be recovered by an external resource provider.
SolutionUsers should upgrade to Elastic Stack version 5.6.13 or 6.4.3. Users unable to upgrade can disable the Reporting feature in Kibana by setting xpack.reporting.enabled to false in the kibana.yml file. This does not prevent previously leaked credentials from being reused.For more information about mitigating from this flaw please see our blog post.
