  script_tag(name:"insight", value:"The following vulnerabilities exist:

  - When using the scalar type hint string in a setter method (e.g. setName(string $name)) of a class
  that's the data_class of a form, and when a file upload is submitted to the corresponding field
  instead of a normal text input, then UploadedFile::__toString() is called which will then return
  and disclose the path of the uploaded file. If combined with a local file inclusion issue in
  certain circumstances this could escalate it to a Remote Code Execution. (CVE-2018-19789)

  - Using backslashes in the _failure_path input field of login forms, one can work around the
  redirection target restrictions and effectively redirect the user to any domain after login. (CVE-2018-19790)");

  script_tag(name:"impact", value:"Successful exploitation would allow an attacker to disclose
  the full path of an uploaded file, execute arbitrary code or redirect a user to any domain after login.");
