CVE-ID  : CVE-2019-7608 CVE-2019-7609 CVE-2019-7610
Package : kibana
Type    : multiple issues
Remote  : Yes
Link    : https://security.archlinux.org/AVG-911

Summary
=======

The package kibana before version 6.6.1-1 is vulnerable to multiple
issues including arbitrary code execution and information disclosure.

Resolution
==========

Upgrade to 6.6.1-1.

# pacman -Syu "kibana>=6.6.1-1"

The problems have been fixed upstream in version 6.6.1.

Workaround
==========

None.

Description
===========

- CVE-2019-7608 (information disclosure)

Kibana versions before 5.6.15 and 6.6.1 had a cross-site scripting
(XSS) vulnerability that could allow an attacker to obtain sensitive
information from, or perform destructive actions on behalf of, other
Kibana users.

- CVE-2019-7609 (arbitrary code execution)

Kibana versions before 5.6.15 and 6.6.1 contain an arbitrary code
execution flaw in the Timelion visualizer. An attacker with access to
the Timelion application could send a request that will attempt to
execute javascript code. This could possibly lead to an attacker
executing arbitrary commands with permissions of the Kibana process on
the host system.

- CVE-2019-7610 (arbitrary code execution)

Kibana versions before 5.6.15 and 6.6.1 contain an arbitrary code
execution flaw in the security audit logger. If a Kibana instance has
the setting xpack.security.audit.enabled set to true, an attacker could
send a request that will attempt to execute javascript code. This could
possibly lead to an attacker executing arbitrary commands with
permissions of the Kibana process on the host system.

Impact
======

An authenticated malicious user can disclose sensitive information or
execute arbitrary code.
