According to its self-reported version number, the instance of SaltStack hosted on the remote server is affected by multiple vulnerabilities:
After receiving several bad packets on the request server equal to the number of worker threads, the master will become unresponsive to return requests until restarted. (CVE-2023-20897)
Git Providers can read from the wrong environment because they get the same cache directory base name.
(CVE-2023-20898)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version
