I never tested this exploit before but if you read carefully to point n. 5:

"5. If the sploit worked, you can connect to port 128 in another terminal"

This means the exploit is not 100% sure working. I bet you followed the
instructions correctly, then the answer to your question is:

the exploit didn't work.

Reasons could be hundreds...

Hi there,

I am trying to exploit a vulnerable version of OpenSSH
(3.1p1) through challenge-response buffer overflow
(BID 5093). I have already checked it meets the
pre-requisites (keyboard-interactive is enabled).
I have compiled the modified version of the client as
explained in
http://downloads.securityfocus.com/vulnerabilities/exploits/openssh3.1obsdexp.txt.

But when it comes to run it (./ssh
root:skey@[SERVER]), the exploit doesn't work: it asks
for the password, as with the original version of ssh.
The target platform is Red Hat Linux.

Has anyone sucessfully exploited this overflow in
Linux?

Thanks in advance. Greetings,

RSMC
