Hello peeps

Anyone here have 2degrees webmail? preferably using a snap domain.

 

Need to confirm if there is a security hole.

1) Change the password to your email address to more than 8 characters long, password can be anything e.g. qwerty12345
2) Attempt to login to your email with only the first 8 characters e.g. qwerty12
3) Report results on this thread.

My email was hacked and was being used to send out spam, then figured out that only the first 8 characters were being used which would of made it much easier for someone to hack.

Issue was logged with 2degrees and it's been sitting with them for close to 3 weeks with no updates. Every time I call them they give me the same bs. They also said I'm the only person impacted by this password issue which I find hard to believe. Most likely they messed up >=8 char security rule and have it logged with their development team to fix which is why it's taking so long to get an answer.

If it is widespread 2degrees would need to notify their customers that their webmail service has a security hole.

Just tried it with a fresh @snap.net.nz address and it did not work. Worked with full password but not first 8 only.

I haven't reset my password but my password is longer than 8 characters.

 

Can confirm I could logon by just using the first 8 characters.

 

Edit: Just confirmed I can put anything after the 8th character and it accepts it. (ie Passwordxyz works when the password is "Password1")

PM'd someone I know at 2Degrees and pointed them at this thread. May help speed things up.





Information wants to be free. The Net interprets censorship as damage and routes around it.

Hey all,

 

We are not aware of any widespread issue with our webmail service at this time.

 

Can those that are affected please message us here privately with the email address in question, along with your broadband customer number and physical address, and we'll be more than happy to look in to this here for you and see what the story is.

 

Thanks,

 

Ralph ^JOB

Just seen the thread and confirm that this is an issue for me.

 

My password was over 8 characters to start with.

Heh... reminds me back in the IHUG days where I found long as you knew someones IHUG username, you could log into their homepage space usage checker with any password - so you could see any "hidden" dirs/files the user had on their site. Told webmaster, they fixed it, then following week restored from an old backup and put the problem straight back.

Many months later, issue still not fixed.

I'm assuming the issue was over their head and they gave up on attempting to fix it. They probably raised a p4 ticket on the day, then once they realised they couldn't fix it decided to resolve + close the ticket with no customer visibility. No ticket ownership, no checking with user, no nothing. 

Decided to give 2degrees a call, got the response "our technical team is still looking into it, and we are waiting for an update from them".

How many months does it take to get an update? You would think an issue like this that is widespread impacting mail security would be considered important.

Scary, that means they're not hashing passwords?

Not necessarily. Perhaps they truncate the password, hash it then store in the database. Still would pass as per OP's description.

Interesting, I don't think they are hashing passwords, because the CSR's have visibility to the password which is very scary indeed. Perhaps their database was already hacked, would explain how my webmail account was compromised and used as a mail bot last year. 

I spoke to one of the CSR's today who seemed more helpful than previous experiences. What we found was that when he changes my password on his end, I can no longer login using only the first 8 characters, and can only login when all characters are matching. However, when I change the password myself through their web portal (https://secure.2degreesbroadband.co.nz/email) it accepts the password as long as the first 8 characters are correct.

 

Perhaps the front-end is truncating the password to first 8 chars before storing to the database? but even that wouldn't make sense, as I can login using any password as long as the first 8 chars are matching. e.g. set password to 'password12345' would be able to login with 'password999' or 'passwordaaaaaa' etc..

Hi @NZGamingIcon,

 

Our technical team have been working on this issue since this was raised in September - thank you again for bringing it to our attention. The issue is the method of encryption we previously used to store these passwords which truncated to 8 characters only.

 

We are now halfway there to resolving the issue, and password changes done by our Customer Care team will use a new encryption method not vulnerable to this issue, however changes online will still use the old method.

 

We're also upgrading all existing passwords to the newer encryption method retroactively, so if your password stops working you may be using/autofilling the truncated version. Just give our team a call on 0800 022 022 opt 9 to get that sorted.

Cheers, ^BRM
