Descriptions

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.

Nextcloud también incluye una utilidad CLI llamada nextcloudcmd que a veces se utiliza para scripts automatizados y servidores headless. Las versiones de nextcloudcmd anteriores a la 3.6.1 confiarían incorrectamente en certificados TLS no válidos, lo que puede permitir un ataque de man-in-the-middle que exponga datos o credenciales confidenciales a un atacante de red. Esto afecta únicamente a la CLI. No afecta a los clientes Nextcloud de escritorio GUI estándar y no afecta al servidor Nextcloud.
