Arch Linux Security Advisory ASA-201708-17
==========================================
Severity: Medium
Date : 2017-08-23
CVE-ID : CVE-2017-12791
Package : salt
Type : directory traversal
Remote : Yes
Link : https://security.archlinux.org/AVG-383
Summary
=======
The package salt before version 2017.7.1-1 is vulnerable to directory
traversal.
Resolution
==========
Upgrade to 2017.7.1-1.
# pacman -Syu "salt>=2017.7.1-1"
The problem has been fixed upstream in version 2017.7.1.
Workaround
==========
None.
Description
===========
It has been discovered that maliciously crafted minion IDs can cause
unwanted directory traversals on the salt-master. The flaw is within
the minion id validation which could allow certain minions to
authenticate to a master despite not having the correct credentials. To
exploit the vulnerability, an attacker must create a salt-minion with
an ID containing characters that will cause a directory traversal.
Impact
======
An unauthenticated attacker is able to craft a malicious minion ID to
cause a directory traversal on the salt-master.
