The remote host has the program CuteFTP.exe installed.

CuteFTP is a FTP client which contains two overflow conditions
which may be exploited by an attacker to gain a shell on this
host.

To exploit these vulnerabilities, an attacker would need to set
up a rogue FTP server and lure a user of this host to browse it
using CuteFTP.

Solution : Upgrade to CuteFTP 5.0.2.0 or newer
Risk Factor : High";
