Read the original description
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.

Questions about CVE-2020-11651
What does this mean?
The bug lets an attacker who can reach the salt-master over the network retrieve user tokens from the master and run arbitrary commands on salt minions. The facts describe the impact but do not give a detailed technical mechanism.Source: sec.cloudapps.cisco.com, lists.debian.org
Am I affected, and how do I check?
Salt versions before 2019.2.4 and versions in the 3000 line before 3000.2 are affected. To check a system, look at the installed Salt version and confirm whether the salt-master service is active (running) and reachable on TCP ports 4505 and 4506.Source: sec.cloudapps.cisco.com, lists.debian.org
What should I do about it?
Upgrade to Salt 2019.2.4 or later, or to 3000.2 or later for the 3000 line.Source: sec.cloudapps.cisco.com, lists.debian.org
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2021-11-03, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
