Unbounce is not vulnerable for subdomain takeover. #11

Closed smiegles closed 4 years ago

smiegles commented 6 years ago

The attacker here used an un-ethical way to exploit Unbounce which is resolved now as far as I believe.

No i think it 's not possible to claim it .

pdelteil commented 3 years ago

Everytime you find an long string identifier, chances you can take the domain are very low.

creimer808 commented 3 years ago

can you bypass Unbounce's control by doing an NSLOOKUP and using the alias associated with the domain that Unbounce has blocked?

I confirm that Unbounce is still vulnerable to subdomain takeovers since I successfully took over a subdomain 17 days ago (23 December 2022).

Are you sure ?

Found a case just like you said and this is what I got

Screenshot from 2021-05-07 00-31-12

this is the same error I am facing, anybody knows if it is still possible to bypass it and take over?

how you bypass the domain error?

There was no error, for me at least. I guess it was pure luck, I guess?

maybe, good for you. What about the txt record entry thing mentioned above, aren't we need to have access to the target's root domain for this? btw I just contacted the support team and they also provide me with an entry to add as Txt record, can I add this in any domain I owned?

Yes you are right

Hi, is there any special indication other than cname, for example from the protocol whether SSL is available, error or not?

mohamadsharabi commented 1 year ago

still vulnerable ?

str0d commented 11 months ago

still vulnerable ?

Unfortunately not possible.

coj337 commented 11 months ago

It's still vulnerable but only as a rare edge case, I exploited a valid one a few days ago - see https://github.com/Stratus-Security/Subdominator/issues/1#issuecomment-1868153929

drealm-PsP commented 10 months ago

Hello @coj337 I recently saw on Unbounce account giving an 404 Status code. Could you please help me confirm if its vulnerable for subdomain takeover with your account? I don't have funds to purchase one. Thank you very much sir.

drealm-PsP commented 10 months ago

If it is, then well share the outcome. Am a bug bounty hunter by the way :)

Hunterdawn82 commented 6 months ago

I was able to add a domain but it says "Error Finding CNAME" How can i resolve this anyone?

drealm-PsP commented 6 months ago

Hello, even after when you add your domain, It is not vulnerable. Just shift your attention to something else.

pdelteil commented 6 months ago

Not true.

If you manage to add a custom domain then there's a complete subdomain take over.

Hunterdawn82 commented 6 months ago

Not true.

If you manage to add a custom domain then there's a complete subdomain take over.

Yeah i think so, it's possible, The domain was pointing at a random ip address while using dig command and when i can subzy it was vulnerable to unbounce subdomain takeover and also when i claimed the subdomain it got claimed but after that it was asking for a cname to go live i guess. So, if anyone knows how to do that please help

drealm-PsP commented 6 months ago

Ok. No challenge. I'll be glad to learn how you will do that. Thanks and regards
