I would not be surprised if this turns into a class action lawsuit. The negligence here is remarkable.

You need damages to have a class action lawsuit. What are your damages? I am not saying no one has damages, but if 100s of people had damages, I expect something would have happened...

Couldn't anyone who lost money on a stock be able to claim damages? How would the bank prove the purchase order was legitimate seeing as there's basically no security around the endpoint and the bank knew it?

Would he not have a case of gross negligence against Zecco if he were a customer? Is there something preventing a lawsuit, outside of the possibly non-binding NDA?

No damages, assuming no unauthorized trades were executed in his account as a result of the unpatched vulnerability.

Lesson learned: when reporting a vulnerability, record all discussions from first contact with the vendor. At least in cases where the vendor doesn't have a clear, easy to find policy and/or bounty for disclosures. I think it's totally fair to reject an NDA but I don't blame him for fearing an overzealous reaction on their part. Even being on the right side of criminal and civil law, you really do have to be willing…

I believe that you'd need to tell them that they were being recorded or you could get yourself into trouble.

Edit: looks like this could be possible without getting into trouble depending on the state you're in: http://lifehacker.com/5491190/is-it-legal-to-record-phone-ca...

> if somebody sent you an email with that code (even if you never open the email) What is he trying to say here? How on earth would it be possible to execute the url in the context of your zecco cookies unless it's openend in a (browser) in which you've logged into zecco?

Some webmail clients (and potentially other web communicators like online chats - FB messenger, etc) might pre-fetch all URLs send in the email or chat.

The pre-fetching will use the user's context (and cookies) because it's executed by the user's web browser.

The NDA is not a valid contract because there is no consideration. For a contract to be valid each party has to gain something. This is why many contracts include a token consideration of $1. This one didn't, so it's invalid.

What about NDAs for interviews? What am I gaining (a chance at getting a job doesn't seem like a gain)?

Are you an IP lawyer?

No. But I can read.

On a similar, but separate note, my bank launched a new version of its online banking platform. From launch I noticed it opened my accounts in a new tab while leaving my credentials (password and all) in the sign-in form. Not so bad when signing in from home - horrific if you're signing in from a public computer. I tweeted to the bank and spoke to someone on the phone about it. It's been 3 months and the bug is still…

Tell us what bank so we can avoid them.

This deserves more than an upvote. This is exactly the right attitude. It puts the incentives in the right place and will let the market do what she does best: work.

> a chance at getting a job

Yes, that is exactly right.

> doesn't seem like a gain

Why not? If you don't think that's a gain, why are you wasting your time doing the interview in the first place?

Consideration is a common law concept as far as I can tell. As someone unfamiliar with how it came to be: Why was consideration introduced? What's the rationale, the goal behind it?

IANAL

A contract is what lets you sue someone over a private transaction. That's what it does, that's all it does. If for whatever reason you're not willing to bring a contract dispute to court, then your contract doesn't do anything and you wasted your time writing it. Contract = right to sue for breach of contract.

In order to sue someone, you need to be able to describe what damages have been done to you. The goal of a lawsuit is for the responsible party to 'make you whole,' i.e. pay you back an amount equal to the damages done to you.

In a contract dispute, the 'damages' of breaking the contract is equal to the 'consideration' of fulfilling the contract. In other words, the promised consideration is the actual thing that you can sue over.

If there is no consideration, then there are no potential damages, and there is no potential lawsuit. And since the only point of a contract is to enable a lawsuit, a contract that doesn't do that isn't a contract.

I think they're regarding these things as weapons, because that's how they or others are using them.

It doesn't matter how we regard CVEs as a community, this is the truth of the matter outside of it. We're handing them over a bomb, and they want to know why. It feels very Spy vs Spy to me, as silly as that sounds.
