Overview

CVE-2022-39334 is a low-severity vulnerability. It was published on November 25, 2022 and has a CVSS 3.1 base score of 3.9 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.9, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
