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.
