Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14650-1 advisory.

- An issue was discovered in SaltStack Salt before 3002.5. The minion's restartcheck is vulnerable to command injection via a crafted process name. This allows for a local privilege escalation by any user able to create a files on the minion in a non-blacklisted directory. (CVE-2020-28243)

- In SaltStack Salt before 3002.5, authentication to VMware vcenter, vsphere, and esxi servers (in the vmware.py files) does not always validate the SSL/TLS certificate. (CVE-2020-28972)

- In SaltStack Salt before 3002.5, when authenticating to services using certain modules, the SSL certificate is not always validated. (CVE-2020-35662)

- An issue was discovered in through SaltStack Salt before 3002.5. salt-api does not honor eauth credentials for the wheel_async client. Thus, an attacker can remotely run any wheel modules on the master.
(CVE-2021-25281)

- An issue was discovered in through SaltStack Salt before 3002.5. The salt.wheel.pillar_roots.write method is vulnerable to directory traversal. (CVE-2021-25282)

- An issue was discovered in through SaltStack Salt before 3002.5. The jinja renderer does not protect against server side template injection attacks. (CVE-2021-25283)

- An issue was discovered in through SaltStack Salt before 3002.5. salt.modules.cmdmod can log credentials to the info or error log level. (CVE-2021-25284)

- In SaltStack Salt before 3002.5, eauth tokens can be used once after expiration. (They might be used to run command against the salt master or minions.) (CVE-2021-3144)

- An issue was discovered in SaltStack Salt before 3002.5. Sending crafted web requests to the Salt API can result in salt.utils.thin.gen_thin() command injection because of different handling of single versus double quotes. This is related to salt/utils/thin.py. (CVE-2021-3148)

- An issue was discovered in SaltStack Salt before 3002.5. 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected salt, salt-doc and / or salt-minion packages.
