SUSE Linux Enterprise Server 15
SUSE Linux Enterprise Server 12
All users of SUSE Linux Enterprise Server and SUSE Manager are affected.
The following issues exist :
- CVE-2020-16846: An unauthenticated attacker with network access to the Salt API could use shell injections to run code on the Salt-API using the SSH client, allowing remote root code execution.
- CVE-2020-25592: eauth tokens were 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, allowing remote root code execution.
- CVE-2020-17490: Salt minions or masters that previously used the create_ca, create_csr, and create_self_signed_cert functions in the TLS module, were exposing the created certificates to local attackers.
These salt security updates should be installed in order to resolve the reported issues
WorkaroundIn case the updates needed to resolve this cannot immediately be applied, a workaround would be blocking ssh access to the salt-api. This might however reduce its functionality.
