CVE-2022-39334
Nextcloud nextcloudcmd TLS Certificate Validation Weakness
Description
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.

Action Type Old Value New Value Changed Description Nextcloud desktop is the desktop sync client for Nextcloud. Versions prior to 3.6.1 would incorrectly trust invalid TLS certificates. A Man-in-the-middle attack is possible in case a user can be made running a nextcloudcmd CLI command locally. It is recommended that the Nextcloud Desktop client is upgraded to 3.6.1. There are no known workarounds for this vulnerability. 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.
