Cloudron Forum

Indeed, we use that angular version 1.5.8 and can look into updating that. Generally though I am not sure how one would exploit this in the Cloudron use-case. So I don't think it makes much difference. The only user-content which is dynamic in that sense would be the footer, but if the admin sets a malicious footer, I guess the situation is already an issue.

@potemkin_ai thanks for reporting. It seems nfs-common depends on rpcbind which starts the service at port 111. rpcbind is only needed for NFSv3 . I have disabled rpcbind in the next release (8.0.1) . Cloudron only supports NFSv4 out of the box.

@nj Cloudro relies on Ubuntu LTS versions and security updates are enabled automatically (independent from Cloudron releases). So once the ubuntu securty team updates the kernels, all Cloudrons will get is as well. Since this is a kernel issue, you will likely see some "reboot required" notification in your Cloudron dashboard afterwards.

@girish I would say pick and choose what is applicable obviously you would know best it's also worth noting there are CIS benchmarks specifically for Docker Containers which might be a better fit. You could combine the two for better hardening. https://www.cisecurity.org/benchmark/docker/ https://github.com/docker/docker-bench-security Let me know what you think

@mastadamus thanks so much for investigating. I have removed it for next release (7.1) - https://git.cloudron.io/cloudron/box/-/commit/6492c9b71f80120413ff4ae7eefa2f03dc96ea0f

Both the old java as well as the bedrock edition have now been updated.

@girish ah i didnt even notice bevause of all the 4j notices my eyes where too open thx for looking at this anyway

@jodumont I recently posted about crowdsec under feature requests. I think crowdsec is more appropriate, afaik, for cloudron

@fbartels I do believe you.

The backdoor was removed before it was compiled into a binary for admins to download so there is no issue for anyone running PHP. However this does prove to be an issues in regards to PHP's safety - They have moved to GitHub (@girish mentions in his reply) and will be better closely monitoring pushes and merges into the code base. PHP's Own Nikita Popov: "The changes were on the development branch for PHP 8.1, which is due to release at the end of the year" which means the code has not been distributed. It's a big deal but not as big as everyone is making it out to be. Hopefully this does NOT happen again.

@mastadamus that will be very useful, thanks!

@girish agreed.

@imc67 I've published a new package which sets the getremoteaddrconf now correctly. Since we only have one reverse proxy, the second setting was not needed in my tests. So this is untouched by default.

Thanks for the heads up. The new package is out now.

Actually, it seems a better way to confirm this is the apt package version and not the dovecot version. The latest one (i.e one which will be in next release) shows this: root@e4d2eb1cba0b:/app/haraka# apt list --installed 2>/dev/null | grep dovecot-core dovecot-core/bionic-updates,bionic-security,now 1:2.2.33.2-1ubuntu4.7 amd64 [installed] The current cloudron container has 1:2.2.33.2-1ubuntu4.6

@girish thanks again for this!

@girish also, I imagine if MailPile hadn't tried to make PGP easy as part of it the developer might not have burnt out and there might be a decent open source webmail app!

@nicolas There's a feature request to monitor network traffic at the app level. If we had that, we could have narrowed this down more quickly.

@nebulon just for information - livepatch doesn't mean you don't have to reboot - it just lets you postpone that moment as convenient. For sync - a good practice on old good *nix is to issue sync twice before reboot - to make sure the buffers dumped for sure. On the reboot automation using third-party apps - it's doable; everything is, but why, if you can just add it inside of the system?
