- 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
