  script.

  - CVE-2020-25352: A stored cross-site scripting (XSS) vulnerability in the '/devices.php' function
  allows remote attackers to perform arbitrary Javascript execution through entering a crafted
  payload into the 'Model' field then saving.

  - CVE-2020-25353: A server-side request forgery (SSRF) vulnerability allows remote authenticated
  attackers to open a connection to the machine via the deviceIpAddr and connPort parameters.

  - CVE-2020-25359: An arbitrary file deletion vulnerability gives attackers the ability to send a
  crafted request to /lib/ajaxHandlers/ajaxDeleteAllLoggingFiles.php by specifying a path in the
  'path' parameter and an extension in the 'ext' parameter and delete all the files with that
  extension in that path.");
