tag_impact = "Successful exploitation allows attackers to execute arbitrary code by
  tricking a user into downloading a directory containing files with
  specially crafted filenames from a malicious FTP server.
  Impact Level: Application";
tag_affected = "Visicom Medias AceFTP Freeware/Pro Version 3.80.3 and prior on W
  Windows";
tag_insight = "The flaw is due to input validation errors when processing FTP
  responses to a LIST command. These can be exploited by attackers when
  downloading the directories containing files with directory traversal
  specifiers in the filename.";
tag_solution = "No solution or patch was made available for at least one year
  since disclosure of this vulnerability. Likely none will be provided
  anymore. General solution options are to upgrade to a newer release,
  disable respective features, remove the product or replace the product by
  another one.

  A workaround is to avoid downloading files and directories from untrusted FTP
  servers.
