Yeah, I tried but with my external IP:

    $ telnet [redacted] 32764
    Trying [redacted]...
    telnet: connect to address [redacted]: Connection refused
    telnet: Unable to connect to remote host

Does this mean my router has no backdoor? Is it clever enough to avoid detection?

Check your internal IP as well, some models are only vulnerable on the LAN.

Metasploit has a check module for this, and will also get you a shell:

Are you running one of the affected hardware models?

No, but I have a fairly uncommon router (not ISP supplied) so I was curious if it also had a backdoor. It doesn't respond on LAN so it seems my DrayTek Vigor 2750N is backdoor-free for now...

That just means it's free of this particular backdoor.

Hence "for now...". A new backdoor could surface tomorrow.
