Impact | Varies from information gathering to a serious compromise of an ftp server. |
Detailed Information | FTP is used to transfer files between hosts. This event is indicative of spurious activity in FTP traffic between hosts. The event may be the result of a transfer of a known protected file or it could be an attempt to compromise the FTP server by overflowing a buffer in the FTP daemon or service. |
