The version of Jenkins running on the remote web server is prior to 2.154 or is a version of Jenkins LTS prior to 2.138.4 or 2.150.1. It is, therefore, affected by multiple vulnerabilities:

  - A command execution vulnerability exists in the Stapler     web framework used in Jenkins due to certain methods     being invoked via crafted URLs. An unauthenticated,     remote attacker can exploit this to invoke methods     never intended to be invoked in this way, which could     potentially lead to command execution. 

  - A denial of service (DoS) vulnerability exists in     Jenkins due to a forced migration of user records.     An unauthenticated, remote attacker can exploit     this issue, via submitting a crafted username to     Jenkins login, which could potentially prevent     valid users from being able to log in.

  - An arbitrary file read vulnerability exists in     Jenkins due to the workspace browser following     symlinks outside the workspace. An attacker     could exploit this to read arbitrary files     outside of the workspace and disclose sensitive     information.

  - A potential denial of service (DoS) vulnerability     exists in Jenkins due to an error in cron expression     form validation. An attacker can exploit this issue,     via a crafted cron expression, to cause the application     to stop responding.

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