In Kibana X-Pack security versions prior to 5.4.3 if a Kibana user opens a crafted Kibana URL the result could be a redirect to an improperly initialized Kibana login screen. If the user enters credentials on this screen, the credentials will appear in the URL bar. The credentials could then be viewed by untrusted parties or logged into the Kibana access logs.

Kibana before 4.5.4 and 4.1.11 when a custom output is configured for logging in, cookies and authorization headers could be written to the log files. This information could be used to hijack sessions of other users when using Kibana behind some form of authentication such as Shield.

Kibana versions prior to 4.1.3 and 4.2.1 are vulnerable to a XSS attack.

Kibana versions prior to 5.2.1 configured for SSL client access, file descriptors will fail to be cleaned up after certain requests and will accumulate over time until the process crashes.

With X-Pack installed, Kibana versions 5.0.0 and 5.0.1 were not properly authenticating requests to advanced settings and the short URL service, any authenticated user could make requests to those services regardless of their own permissions.

With X-Pack installed, Kibana versions before 5.3.1 have an open redirect vulnerability on the login page that would enable an attacker to craft a link that redirects to an arbitrary website.

Kibana versions after and including 4.3 and before 4.6.2 are vulnerable to a cross-site scripting (XSS) attack.

Kibana versions before 4.6.3 and 5.0.1 have an open redirect vulnerability that would enable an attacker to craft a link in the Kibana domain that redirects to an arbitrary website.

Kibana before 4.5.4 and 4.1.11 are vulnerable to an XSS attack that would allow an attacker to execute arbitrary JavaScript in users' browsers.

Kibana Reporting plugin version 2.4.0 is vulnerable to a CSRF vulnerability that could allow an attacker to generate superfluous reports whenever an authenticated Kibana user navigates to a specially-crafted page.
