CVE-ID  : CVE-2020-11651 CVE-2020-11652
Package : salt
Type    : multiple issues
Remote  : Yes
Link    : https://security.archlinux.org/AVG-1147

Summary
======
The package salt before version 2019.2.4-1 is vulnerable to multiple

Upgrade to 2019.2.4-1.

# pacman -Syu "salt>=2019.2.4-1"

The problems have been fixed upstream in version 2019.2.4.

Workaround

Description
==========
- CVE-2020-11651 (arbitrary command execution)

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000
before 3000.2. The salt-master process ClearFuncs class does not
properly validate method calls. This allows a remote user to access
some methods without authentication. These methods can be used to
retrieve user tokens from the salt master and/or run arbitrary commands
on salt minions.

- CVE-2020-11652 (arbitrary filesystem access)

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000
before 3000.2. The salt-master process ClearFuncs class allows access
to some methods that improperly sanitize paths. These methods allow
arbitrary directory access to authenticated users.

Impact
=====
A remote unauthenticated user can execute arbitrary commands and access
files on the affected host.
