"The version of Jenkins running on the remote web server is prior to
2.89 or is a version of Jenkins LTS prior to 2.73.3.
It is, therefore, affected by multiple vulnerabilities :

  - Jenkins contains a flaw that allows traversing outside of a
  restricted path. The issue is due to the program not properly
  sanitizing user input, specifically slashes and path traversal
  style attacks (e.g. '../') supplied via usernames. With a
  specially crafted username, a remote attacker can overwrite
  arbitrary files on the system.

  - Jenkins contains a flaw that allows a stored cross-site
  scripting (XSS) attack. This flaw exists because the program
  does not validate autocomplete suggestions before returning it
  to users. This may allow a remote attacker to create a specially
  crafted request that will execute arbitrary script code in a
  user's browser session within the trust relationship between
  their browser and the server.

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