    There was a chap on here the other day who said they hate 2fa and don’t need it because they use passwords that are 50 characters and generated by the password manager.

    This is a perfect example of why you should always activate it when possible.

      Alot of people don’t like Microsoft, but they’re pushing for zero password authentication for a reason. Passwords are getting really insecure really fast.

        This vulnerability has nothing to do with password strength or security and everything to do with password reset security, i.e. email and improper handling of parameters to that reset API call.

        Passkeys are interesting and potentially quite strong but they’re going to have to fall back to the same old reset mechanism if you e.g. drop your passkey device (phone) into a lake.

          Or just make it clear your account is gone if you lose your passkey, so have a second key for backup or learn a hard lesson.

            Yeah, good luck with that. You can tell someone “if you lose this token, all data are unrecoverable”, they’ll reply with “ok, got it!” and about two and a half second later call you saying “Hey I lost my token can you recover my data?”.

              Hence the “hard lesson” part. A lot of us tech-focused people learned the same lesson with our document backup systems. You lose some important documents, then you realize you really should backup your stuff. All I hope is these people learn the lesson earlier in life before the consequences become more and more severe.

          I just use their Authenticator app out of convenience, I get a notification when I login through it and it asks me to input the correct number given by the app, a 2 digit number.

          Not entirely, but now MS, and a lot of other companies, are pushing passkeys. I still prefer password + hardware 2fa but it’s safer than people reusing the same password everywhere.

            I am a fan of passkeys. Particularly because they essentially function as hardware 2fa, except they’re the only factor, which isn’t as big of a problem because it’s not something you can steal in a service breach like passwords. I’ve also noticed that even when using passkeys, most sites let you force a TOTP code as well anyway.

              Very true, the big issue with them is a lot of popular hardware keys, including the yubikeys that I have, are limited to the number passkeys they can store (yubikey is 25 unique). Luckily password managers are starting to support them, but now you’re back to having a strong password + hardware 2FA to store those passkeys anyway.

              I do like TOTP or just hardware 2FA as a backup for my passkeys. What I really can’t stand is sties that only offer SMS as 2FA, it makes me more angry than it probably should.

                iPhones natively support passkeys, so at the very least the iOS user base can easily use them. Not sure about Android though.

      I see a lot of people around me resetting passwords of services they rarely use because they forgot what password they used and don’t have a password manager (or not synced one). And I don’t understand why all services don’t propose to generate a one time link to log in instead of changing passwords (a few services do propose it already)

      Passwords are useless for all users using the same password for every account they have, and i’m sure it’s a majority of users.

      I don’t have 2FA for my GitLab account since it’s only accesible via my GitHub account which has 2FA. Is this good or should I add 2FA to GitLab also?

          This isn’t necessarily true. If you are using an identity provider, you can still perform a password reset on GitLab and set a password there, bypassing your 2FA on GitHub. You usually shouldnt rely on IdP 2FA unless the destination system enforces IdP signin every time. There is a group setting in GitLab that does that, but it will only apply for that group.

      One of the biggest issues with 2fa is that normally it’s either an easily spoofable phone/email or an app locked to a device.

      This is why I use a password manager (pass) that is synced across all of my devices (via a private self hosted git for version control) that I can send 2fa QR codes to cameraless devices via screenshots using zbarimg and have every device capable of 2fa verification with the pass-otp extension.

      I know this setup is a bit complicated as just dealing with git or importing a gpg key would give most people I know sense of existential dread. I am curious to see what others use for similar functionality.

        Is that second factor, though? If I understand it right, you are basically generating your MFA from your password manager, is that so?

          I’m just using my password manager in place of the authenticator app.

          So rather than using an app like Google authenticator or Authy to see what the new random sequence is for the MFA, my password manager stores that QR as a string and will display the same random sequence that a normal MFA app would.

          They key difference is that my MFA is synced across any device that I have configured my password manager on using the same cryptographic keys and version control history.

          So if my phone is dead, lost, or stolen, I can still access my banking account via MFA as normal.

          I suppose it brings up the idea of what a “factor” is in how it’s used for MFA. If a factor is supposed to be a different device, a different app on the same device as your password manager, or just a different passphrase that’s constantly changing.

            I see. IIRC from school, “factor” actually has a definition - it’s either something you have (keycard, phone), something you are (biometrics) or something you know (password).

            For authentication to be truly an effective MFA, it would have to require at least two of those factors. And that’s also why I.e email isn’t really a MFA.

            So, I guess it boils down to where are you storing your passwords. If they are also in the password manager, then, its only 1FA, because knowing your password manager password is enough to defeat it. (Or, if someone finds a zeroday in the pass manager).

              It’s still two separate passwords so I think it qualifies as 2 factors.

              But yes the password manager has one gpg key which only has one passphrase used to decrypt the passwords saved in the password manager. So if that was compromised then so would all passwords

    We use gitlab ultimate at my work, I’m the main admin of the instance. Like 2 weeks ago when there was the cvss 10 vuln, gitlab sent us a .patch file to apply to the instance instead of releasing a new minor cause they didn’t wanna make the vuln public yet. I guess that’s coordinated disclosure, but I still found that remarkably jank.

        No it doesn’t. Gitlab’s pricing has been pretty stable, with one increase in the premium tier in the past six years ($19 --> $29 per user per month).

          There were more increases, they just changed the tier names and billing terms, so it’s somewhat hard to find historical information of previous prices. Our company ditched it after the 52% increase in 2023, especially because we were still adjusting to the price increase from 2021, which for us was $6 per user per month. I think in 2018 or 2019 it was $3 per user per month, so there must have been another increase that happened between 2018 and 2021. This was all for self hosted, so we had the additional cost of hardware and to maintain the services.

          I really wanted to support GitLab, but the price simply became too much to justify.

    Check gitlab-rails/production_json.log for HTTP requests to the /users/password path with params.value.email consisting of a JSON array with multiple email addresses.

    Jesus Christ. Their frontend was sending a list of recipients to the backend. That’s an intern developer level of fuck up, in their login system, no less.

    If this got past them, it’s a sign of deep problems.

        Gitlab has a backend, which runs on a server, and a frontend, which runs in all the user’s browsers. When the user does anything it sends some network requests to the backend in order to save the changes the user has made, send the necessary emails or create a session, etc.

        The thing with this architecture is the backend and frontend are effectively separate apps. Also as the frontend is running remotely on the attacker’s computer the attacker can change it to behave however they want. The backend can’t trust the frontend to “do the right thing”, ever. The backend needs to assume the frontend will do every bad and silly thing possible, and treat anything coming from the frontend with maximum suspicion.

        So you simply can’t allow the frontend code to provide a list of email addresses to send an email to, because it’ll allow the attacker to send emails to anywhere. Where the email goes to needs to be determined by the backend. The frontend should only be concerned with hiding and showing stuff in the UI, and pretty much all intelligence and business logic needs to reside on the server where we control the code and environment. A good understanding of the roles and responsibilities of the front vs back is a fundamental concept and if the developer hasn’t grasped this then they’re going to introduce security problems everywhere they go.

        This is one of many pitfalls of the “frontend + backend” architecture. I vastly prefer to build monoliths instead.

        Not the commenter but it seems like the parameters of the HTTP Get/Post weren’t protected/checked. The API was likely something like: Email to reset: string(email account to reset) But it accepted something like: [string(email account to reset), string (email to which the reset mail is sent to)]

            Bobby table, this, buffer overflow… Are all similar in spirit.

            Bobby table is a way for hiding the malicious SQL query after a normal query (in that case after the select with “Bobby” you inject the malicious drop table)

            In this case after the normal email (that normally would serve for both identifying the user and for the mail to send the recovering mail), the attacker sends two mails, the first is fo identifying the user the second to send the recovering mail

            In the case of buffer overflow you inject malicious code after normal(-ish) data

            It’s not an XHR attack since for the mail recovery workflow you don’t need an authenticated session.

            To be a bit more compassionate to the developers, this is probably some dynamic typing problem. Probably ruby is “smart” into understand that an array can contain strings after all… So an array of strings is as good as a string… But here we go into static vs dynamic typing… And it’s a bit of religious war (fun fact in 2011 i was advocating with Guido Van Rossum in having at least an optional static typing check in Python - at the time the discussion was how to make python faster/compiled - and he was borderline mocking me 😅 and few years after pytypes but still no compilation at horizon 😂)
