More information:

Several vulnerabilities were discovered in salt.

  • CVE-2020-16846

    An unauthenticated user with network access to the Salt API can use shell injections to run code on the Salt-API using the SSH client

  • CVE-2020-17490

    When using the functions create_ca, create_csr, and create_self_signed_cert in the tls execution module, it would not ensure the key was created with the correct permissions.

  • CVE-2020-25592

    Properly validate eauth credentials and tokens along with their Access Control Lists – ACLs. Prior to this change, eauth was not properly validated when calling Salt SSH via the salt-api. Any value for “eauth” or “token” would allow a user to bypass authentication and make calls to Salt SSH

For Debian 9 stretch, these problems have been fixed in version 2016.11.2+ds-1+deb9u6.

We recommend that you upgrade your salt packages.
