SaltStack < 3002.5 Multiple Vulnerabilities

critical Nessus Plugin ID 148112


The version of SaltStack running on the remote server is affected by multiple vulnerabilities.


According to its self-reported version number, the instance of SaltStack hosted on the remote server is affected by multiple vulnerabilities:

- The Salt-API’s SSH client is vulnerable to a shell injection by including ProxyCommand in an argument, or via ssh_options provided in an API request. (CVE-2021-3197)

- The Salt-API does not have eAuth credentials for the wheel_async client. Thus, an attacker can remotely run any wheel modules on the master. (CVE-2021-25281)

- eauth tokens can be used once after expiration. They can be used to run command against the salt master or minions. (CVE-2021-3144)

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


Upgrade to SaltStack version referenced in the vendor security advisory.
