CVE-2020-11651 (GCVE-0-2020-11651)
Vulnerability from cvelistv5 – Published: 2020-04-30 16:58 – Updated: 2025-10-21 23:35Summary
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.
