"The remote web server hosts a version of Jenkins that is prior to 2.121, or a version of Jenkins LTS prior to 2.107.3. 
It is, therefore, affected by the following vulnerabilities :

  - An information disclosure vulnerability exists in the AboutJenkins.java & ListPluginsCommand.java classes of 
    Jenkins. An unauthenticated, remote attacker can exploit this to disclose installed plugins on the remote server 
    (CVE-2018-1000192).

  - A directory traversal vulnerability exists in the FilePath.java & SoloFilePathFilter.java classes of Jenkins. An 
    unauthenticated, remote attacker can exploit this, by sending a URI that contains directory traversal characters, 
    to disclose the contents of files located outside of the server's restricted path (CVE-2018-1000194). 
    
  - A server-side request forgery (SSRF) vulnerability exists in the ZipExtractionInstaller.java class of Jenkins. An 
    attacker may exploit this to force Jenkins to send a HTTP get request to an arbitrary URL and glean what the 
    response code was (CVE-2018-1000195).");
