KeePassXC is not affected by this vulnerability.

CVE-2023-32784

That's not the issue mentioned in the article. Which is CVE-2023-35866.

This is also the vulnerability that made many people delete Keepass 2 for XC many months ago so it is very strange that they make an article that sounds like it's a new vulnerability.

[-] dog@suppo.fi 1 points 1 year ago* (last edited 1 year ago)

Wrong vulnerability. The discovered one is CVE-2023-35866, which is still pending verification.

This affects KeePassXC. https://nvd.nist.gov/vuln/detail/CVE-2023-35866

Thanks for the correction. In that case going to be interesting how this issue progress.

[-] laskobar@feddit.de 6 points 1 year ago

Lock the pc, if you leave and lock the db, if pc is locked, lid is closed and this is absolute a non-issue.

German BSI is sometimes a little bit over motivated ;-)

Can't read German. What is required to perform this attack?

[-] lowleveldata@programming.dev 7 points 1 year ago

Ok I checked it up (CVE-2023-35866). It basically says an attacker may export everything if they have access to your unlocked database. Which seems... obvious? The project contributors says it's not a vulnerability which I incline to agree.

You mean to say that if I leave my door unlocked, somebody might come in? This is shocking news!

Here is KeePassXC's response: https://keepassxc.org/blog/2023-06-20-cve-202335866

Basically some random guy with weird misconceptions about security decided this was an issue, it's obviously not. Honestly concerning that he was able to easily get a CVE for this and even get articles about it published on some websites.

It's a denial of service vulnerability. Requiring the existing master password to change the master password will stop a drive by miscreant denying you access to your db. And password change system I've ever used has required the existing password to he entered first.

Likewise a full db export feel like a big enough deal to require authorization.

If you're careful and lock your machine when you leave it then you should be pretty safe. I'm surprised these aren't already features.

[-] Eufalconimorph@beehaw.org 5 points 1 year ago

No, requiring the existing master password won't help. A drive by miscreant with access to an unlocked computer with an unlocked DB can delete all the DB entries. If the DB is locked they can just delete the DB file. KeePassXC can't defend against this, that takes properly functioning versioned backups.

[-] blackstrat@lemmy.fwgx.uk 1 points 1 year ago

yeah, maybe denial of service isn't it. I replied to a comment above why I think it should still be protected functionality to help prevent data leak.

[-] hello_world@feddit.uk 1 points 1 year ago

They could just delete the file to deny you access to your db?

[-] blackstrat@lemmy.fwgx.uk 1 points 1 year ago

Yeah, that's fair. But a full db export that they could then email themselves. It'd be nice to have some more protection against that. Or Change the master password and email the encrypted file to themselves.

Why is there no link to the article?

[-] 73kk13@discuss.tchncs.de 2 points 1 year ago

There is of you click on the image.

[-] chaddy@feddit.de 2 points 1 year ago

On Jerboa(List View) the link is on the thumbail, maybe it's the same in the browser version. Keep in mind that the article on heise is in german.
