"The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3229
advisory.

  - log4js-node is a port of log4js to node.js. In affected versions default file permissions for log files
    created by the file, fileSync and dateFile appenders are world-readable (in unix). This could cause
    problems if log files contain sensitive information. This would affect any users that have not supplied
    their own permissions for the files via the mode parameter in the config. Users are advised to update.
    (CVE-2022-21704)

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