@sumgro Microsoft haven't patched the service and you are doing everything ok.
You are getting a error message because the Traffic Manager profile actually EXIST, so you are unable to claim it. When you make a DNS request to *.trafficmanager.net and get NXDOMAIN there are two possible outcomes:
- The Traffic Manager with requested name really don't exist - you can go ahead and register it. In this context it is likely that the Subdomain Takeover is possible.
- (From my own testing) Traffic Manager profile can be created, however there is no requirement to assign it any endpoints by default. Traffic Manager (as the name) implies is trying to distribute network traffic using different settings and acts just as a middleman. This means that in order it to work, you need to set up endpoints (a.k.a. FQDN) where the traffic will be forwarded once the user reaches to something.trafficmanager.net. Now to the core of the problem: When there is no endpoint assigned in the profile, you will get the same NXDOMAIN response as you would get with non-existing TM profile. In this case, you won't be able to take in over because the TM profile with the name in CNAME record actually exist, it just seems that the profile does not exist.
It is pretty easy to setup a automation for that using Azure API. You would need to test a creation of particular TM profile and not rely only on DNS request as some external indicator of TM profile existence.
Hope it helps.

I've come across a sub-domain, pointing to an azure web app service. This CNAME itself has 3 levels like xyz.abc.m.azurewebsites.net. It shows the NXDOMAIN error when checking with dig.
However, when I try to create the App on the Azure Portal as xyz.abc.m to takeover, it does not allow periods in the same. Anyone aware of how can such scenario be handled for sub-domain takeover?
Thanks

Is this still vulnerable ? Because Azure requires a unique Custom Domain Verification ID to be put as a TXT record in the DNS.
Until the TXT record is configured the following error will show up
I have only tried this for Web Apps (.azurewebsites.net)
from can-i-take-over-xyz.
Never mind, itโs still vulnerable. Just observed one get snatched live. ๐
from can-i-take-over-xyz.
I also faced this. I found a subdomain that resolved to xyz.easteurope.cloudapp.azure.com
and could not use the .
character. Anyone else got around this?
Edit: turns out you could take over this by registering an Azure VM in the easteurope region ;)
from can-i-take-over-xyz.
If the sub-domain points to traffic manager service for Azure, is the takeover possible? When attempting to create a traffic manager profile using the same name as in the CNAME, getting error which mentions "Domain name xyz.trafficmanager.net already exists. Please choose a different DNS prefix".
Has Microsoft patched the service or am I doing something wrong?
Thanks
from can-i-take-over-xyz.
I think it is a Edge case too.

how can i claim this *.cloudapp.azure.com ?
You can simply create a Virtual Machine in the specific region and then in the left menu select "Configure" and set a desired DNS name label.
The format of the URL will be:
<dnsname>.<region>.cloudapp.azure.com

App services (ending with *.azurewebsites.net) does not seem to be vulnerable anymore with the TXT verification as stated here https://docs.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-domain#get-a-domain-verification-id.
A TXT record is required to verify ownership of the domain.
I cannot get it to work. Can anyone confirm this?

today I tried to takeover a cname address called * .azurewebsites.net. I got this cname name, but it was necessary to add a custom domain. when i wanted to do this i got a warning and asked me to add TXT records issued by azure to my dns records. Since I was never able to do this, takeover is not possible.

I was able to do a takeover only a week ago for azurewebsites.net. You aren't doing the takeover correctly. Make sure it is a azure "web app" (costs money to keep online) and then you can add a custom domain.
from can-i-take-over-xyz.
Any verify.profilename.azureservice.tld is not vulnerable since they are just entries for verifying domain ownership. For azure edge or with new name front door previews it's cdnverify, for azurewebsites it's awverify etc.
So when you see such entry ignore them, however profilename.azureservice.tld is still vulnerable if pointing NXDOMAIN, only few edge cases for trafficmanager.net when profile owner just disabled it, so you have 50/50 chance to takeover them, all others when having NXDOMAIN results are vulnerable.

Are *.cloudapp.net takeovers still possible in 2021? I heard the old azure xplat cli (https://github.com/Azure/azure-xplat-cli) can be used to create classic VMs but i'm still forced to do it using the Resource Manager instead:

cname *.trafficmanager.net are vuln or not ?
from can-i-take-over-xyz.
It seems taking over xyz.cloudapp.net subdomains is no longer possible, at least using new deployments, maybe someone who already have the old Azure Cloud Servce (classic) running can change it's url to the dangled DNS name

Yup, these are still vulnerable. I was able to take over one today.

Hello,
Can you provide more information ?
-
Login to your Azure console
-
Create a traffic manager profile, and enter the name of the domain you wish to take over.
-
Open the traffic manager profile you created, and add an external endpoint with an IP pointing to your VPS. The idea is that all traffic will be load balanced to it.
Enjoy your takeover! :)

Hi All,
Hope you are good!
if a Azure Domain not Respond with NXDOMAIN that means it is not Vulnerable.
But if it shows this ;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR,
Then what would be the answer is it vulnerable or not!
Hope you understand my points

Linked back on the main repository, closing this as @Sechunt3r's comment is already addressed in @PatrikHudak's summary.
from can-i-take-over-xyz.
if subdomain return public IP is possible subdomain takeover?
from can-i-take-over-xyz.
Thank you for the revert @PatrikHudak, really appreciate the detailed reply.
I'm fairly new to the subdomain takeover subject. When testing for the subdomain in question, the dig <subdomain.domain.com> confirmed the error NXDOMAIN (thereby bringing a smile) and then the CNAME pointed to xyz.trafficmanager.net.
From your reply, I understand that the profile already exists with the same name as the CNAME, even when the end-point may not have been setup, this results in the error message both when visiting the link and through the dig command. Hence, the takeover for in this situation may not be successful.
Not able to get the pointers on the Azure API for automation, kindly point in the direction to be able to research more on the topic to get an understand for future hunting.
Thanks

Hello everyone,
I was following @PatrikHudak steps in this blog https://0xpatrik.com/subdomain-takeover-starbucks/ to takeover cloudapp.net subdomain but when I deploy my cloud service I get the following error.
"The requested VM tier is currently not available in Central India for this subscription. Please try another tier or deploy to a different location."

I've seen the comments of all participants and few are in doubt that Azure takeover is not vulnerable anymore.
But let me assure you the takeover is certainly possible and I've confirmed it on microsoft.com domain, if you don't want to believe my comment then go to this link "http://smpaccountexceptionservice-int.dps.microsoft.com"

Hi everyone!
I've found subdomain that can be taken over and which is registered on *azurewebsites.net. I'm getting this in return when I type dig
command:
But when I register website on the portal.azure.com -> Custom Domain Names it is still asking me to define TXT or MX, but I'm not allowed to do that. Status of claimed domain is "Unverified" and I don't know what to do next.
Next thing is when I'm adding custom domain and when I try to enter CNAME of that domain, I'm getting in return message which says: "The value must have a length of at most 48." because that link of the CNAME is very long.
Can someone give me a hint what to do next in order to claim this subdomain?
Thanks in advance guys!

@ravkishu Well I need to create a CNAME and a TXT record on the victims domain (let's say google.com). There is no way that I can verify the ownership of the domain by creating a TXT record.

Without the validation, traffic is not routed to the app service. In that case I am presented with a 404 screen as people has posted previously.

I have verified that Cloud Services (ending with *.cloudapp.net) are still vulnerable and does not require domain validation. Just create a resource with the same name as the dangling domain.

One of the subdomains let's say blah.blah.blah.target.com is pointing to blah-blah.azurewebsites.net but in the dig authority section it is pointing to another subdomain of the target but the other subdomain has no name.

today I tried to takeover a cname address called * .azurewebsites.net. I got this cname name, but it was necessary to add a custom domain. when i wanted to do this i got a warning and asked me to add TXT records issued by azure to my dns records. Since I was never able to do this, takeover is not possible.
I was able to do a takeover only a week ago for azurewebsites.net. You aren't doing the takeover correctly. Make sure it is a azure "web app" (costs money to keep online) and then you can add a custom domain.
i know what i'm doing. i did create web app. I wanted to add a domain from custom domain options, but azure gave me a warning telling me to upgrade my plan otherwise I will not be able to add a domain. After upgrading my plan, the add domain button became active and I typed the subdomain name of the target site and clicked the check button. But while doing this, a new warning appeared and gave me some txt information and asked me to add it to the dns records. I turned it off as i could never do this. https was active in the dashboard section. I turned this option off and did the same, but the result was the same.
there is only one thing I have to tell you. example This was the target subdomain address.
awverify.test-bla.target.com
and this example cname
awverify.bla-bla.azurewebsites.net
when i tried to get this address azure did not allow this (awverify.bla-bla)... azure did not allow dot use. so i just tried to get this.(bla-bla)...I just tried to get this address with the hope that I could discover something new. maybe there is a problem with the cname address I want to get.If you think the cname addresses I explained in the example above can be received, we can cooperate.

I remember having a similar txt option and I just skipped it (possibly just pressing continue or yes?) and it worked fine. If domain verification succeeds then it's fine even if you still get the 404.
Try claiming:
*.bla-bla.azurewebsites.net
and
bla-bla.azurewebsites.net
And send the results.

Hi, I'm new to this, any help is really appreciated, I have a subdomain that is pointing to {{something}}.azurewebsites.net, but when I'm trying to create an app service in azure and register {{something}}.azurewebsites.net, it's giving me following error -
The app name {{something}} is not available
But here everyone is saying that it's possible to takeover these, I'm attaching the ui in actual subdomain when I visit that.
Please, someone help me on this.
Thanks.
from can-i-take-over-xyz.
Theres two parts to these types of subdomain takeovers, Firstly the {{something}}.azurewebsites.net registration. This is the creation of the service which in your case has been done by someone.
Secondly once you have created the service you must link the vulnerable subdomain {{something}}.example.com as a "custom domain" In this case, this has not been done.
Unfortunately this case you cannot take over the subdomain. Vulnerable Microsoft takeovers normally return a NXDOMAIN when you do a dns lookup for the subdomain.
from can-i-take-over-xyz.
In my case it's returning NOERROR, And all other informations I've already provided already, so does this mean this subdomain is not possible to takeover? And pardon me for asking, generally *.azurewebsites.net are still vulnerable to subdomain takeovers?
Thanks anyway for clarifying these to me.
from can-i-take-over-xyz.
Yeah so a NOERROR means the DNS lookup worked and the host is alive. So in your case this subdomain is not possible to be taken over as its already registered just not assigned the custom domain. But due to the subdomain.example.com is pointing to this registered resource, this is stopping you from taking it over. So I guess the rule of thumb, I believe (anyone correct me if im wrong) and Subdomain DNS record that is pointing to a Microsoft Azure domain like the "azurewebsites.net" that return a NXDOMAIN is able to taken over (with the exception to "*.trafficmanager.net".
from can-i-take-over-xyz.
Thanks for the detailed clarification, it was very much needed for me, hoping to get subdomain takeover next time.
Happy hacking!

Hello,
It's still vulnerable. Some domains would require domain ownership while others won't.

I've come across a sub-domain, pointing to an azure web app service. This CNAME itself has 3 levels like xyz.abc.m.azurewebsites.net. It shows the NXDOMAIN error when checking with dig.
However, when I try to create the App on the Azure Portal as xyz.abc.m to takeover, it does not allow periods in the same. Anyone aware of how can such scenario be handled for sub-domain takeover?
ThanksHave you found any solution for multi-level domain takeover? Facing the same problem.
Nope, not yet... Please share if you come across the solution.
Thanks
Is this still the case for multilevel [trafficmanager.net] domains?

@pdelteil I recently took over a
azure-api.net
successfully :)How? Describe the steps!
Hi @pdelteil
Login to the portal and search for
Api Management
and selectAPI Management Services
thencreate API management service
and configure accordingly - region, name, etc. It does take about 30-40 mins to be deployed though.
Can you please let me know if it is still vulnerable or not found a subdomain with status : NXDOMAIN and dont know how to take over it , can you describe the steps please

Even after claiming cname pointing to azurewebsites.net, it requires TXT record verification for the vulnerable subdomain. So I think it's not vulnerable anymore.

If the *.cloudapp.net responds with 0.0.0.0 is it vulnerable to takeover
