SaltStack 3000 < 3005.4 / 3006 < 3006.4 Security Bypass

medium Nessus Plugin ID 185733

Language:

Synopsis

The version of SaltStack running on the remote server is affected by security bypass vulnerability.

Description

According to its self-reported version number, the instance of SaltStack hosted on the remote server is affected by a security bypass vulnerability. The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script with the privileges of the user running Salt-SSH.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version

Solution

Upgrade to SaltStack version referenced in the vendor security advisory.
