Date    : 2020-01-29
CVE-ID  : CVE-2019-17361
Package : salt
Type    : arbitrary command execution
Remote  : Yes
Link    : https://security.archlinux.org/AVG-1087

Summary
=======

The package salt before version 2019.2.3-1 is vulnerable to arbitrary
command execution.

Resolution
==========

Upgrade to 2019.2.3-1.

# pacman -Syu "salt>=2019.2.3-1"

The problem has been fixed upstream in version 2019.2.3.

Workaround

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

With the Salt NetAPI enabled in addition to having a SSH roster
defined, unauthenticated access is possible when specifying the client
as SSH. Additionally, when the raw_shell option is specified any
arbitrary command may be run on the Salt master when specifying SSH
options.

Impact
======

A remote unauthenticated attacker is able to execute arbitrary code on
the affected host.
