|
|
This module exploits the KarjaSoft Sami FTP Server version 2.02
|
|
by sending an excessively long USER string. The stack is overwritten
|
|
when the administrator attempts to view the FTP logs. Therefore, this exploit
|
|
is passive and requires end-user interaction. Keep this in mind when selecting
|
|
payloads. When the server is restarted, it will re-execute the exploit until
|
|
the logfile is manually deleted via the file system.
