CVSS: 4.7EPSS: 0%CPEs: 1EXPL: 1CVE-2022-39334 – nextcloudcmd incorrectly trusts bad TLS certificates
https://notcve.org/view.php?id=CVE-2022-39334
Nextcloud also ships a CLI utility called nextcloudcmd which is sometimes used for automated scripting and headless servers. Versions of nextcloudcmd prior to 3.6.1 would incorrectly trust invalid TLS certificates, which may enable a Man-in-the-middle attack that exposes sensitive data or credentials to a network attacker. This affects the CLI only. It does not affect the standard GUI desktop Nextcloud clients, and it does not affect the Nextcloud server.

CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-41882 – Nextcloud Desktop vulnerable to code injection via malicious link
https://notcve.org/view.php?id=CVE-2022-41882
The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server with your computer. In version 3.6.0, if a user received a malicious file share and has it synced locally or the virtual filesystem enabled and clicked a nc://open/ link it will open the default editor for the file type of the shared file, which on Windows can also sometimes mean that a file depending on the type, e.g. "vbs", is being executed. It is recommended that the Nextcloud Desktop client is upgraded to version 3.6.1. As a workaround, users can block the Nextcloud Desktop client 3.6.0 by setting the `minimum.supported.desktop.version` system config to `3.6.1` on the server, so new files designed to use this attack vector are not downloaded anymore. • https://github.com/nextcloud/desktop/pull/5039 https://github.com/nextcloud/desktop/releases/tag/v3.6.1 https://github.com/nextcloud/security-advisories/security/advisories/GHSA-3w86-rm38-8w63 https://github.com/nextcloud/server/pull/34559 • CWE-94: Improper Control of Generation of Code ('Code Injection') •
