The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2022-39334)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4303 advisory.

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2023:0090-1 advisory.

  - Nexcloud desktop is the Desktop sync client for Nextcloud. An attacker can inject arbitrary HyperText     Markup Language into the Desktop Client application in the notifications. It is recommended that the     Nextcloud Desktop client is upgraded to 3.6.1. There are no known workarounds for this issue.

  - The Nextcloud Desktop Client is a tool to synchronize files from a Nextcloud Server with your computer.
    Versions prior to 3.6.3 are missing sanitisation on qml labels which are used for basic HTML elements such     as `strong`, `em` and `head` lines in the UI of the desktop client. The lack of sanitisation may allow for     javascript injection. It is recommended that the Nextcloud Desktop Client is upgraded to 3.6.3. There are     no known workarounds for this issue.
