SaltStack Patches Critical Vulnerabilities in Salt
SaltStack has released a security update to address critical vulnerabilities affecting Salt versions prior to 2019.2.4 and 3000.2. Salt is an open-source remote task and configuration management framework widely used in data centers and cloud servers. A remote attacker could exploit these vulnerabilities to take control of an affected system. These vulnerabilities were detected in exploits in the wild.
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.
