VUL-0: CVE-2023-32320: nextcloud: bruteforce protected details by sending multiple parallel requests
Last modified: 2024-04-16 08:13:09 UTC
CVE-2023-32320 Nextcloud Server is a data storage system for Nextcloud, a self-hosted productivity platform. When multiple requests are sent in parallel, all of them were executed even if the amount of faulty requests succeeded the limit by the time the response was sent to the client. This allowed someone to send as many requests the server could handle in parallel to bruteforce protected details instead of the configured limit, default 8. Nextcloud Server versions 25.0.7 and 26.0.2 and Nextcloud Enterprise Server versions 21.0.9.12, 22.2.10.12, 23.0.12.7, 24.0.12.2, 25.0.7 and 26.0.2 contain patches for this issue.

fixed in Factory, but needed in Backports
(In reply to Robert Frohl from comment #1) > fixed in Factory, but needed in Backports Unfortunately no chance, because the versions in Leap are too old. And the displayed update versions are only Enterprise. The versions do not exist in the community version.

At least looking at server:php:applications/nextcloud it looks like they build successfully.
i.e. wondering if there is something I could help with to unblock the update to a newer version
You can only update from one major to the next. You can't skip any of them. That leads to a crash. But it has always been like that. And even if that works from one major to another when you have an old minor, I don't know yet.
whats going on? Can i close?
