FreeBSD : tailscale -- Insufficient inbound packet filtering in subnet routers and exit nodes (ee6936da-0ddd-11ef-9c21-901b0e9408dc)

high Nessus Plugin ID 195235

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ee6936da-0ddd-11ef-9c21-901b0e9408dc advisory.

 - Tailscale team reports: In Tailscale versions earlier than 1.66.0, exit nodes, subnet routers, and app connectors, could allow inbound connections to other tailnet nodes from their local area network (LAN). This vulnerability only affects Linux exit nodes, subnet routers, and app connectors in tailnets where ACLs allow src: *, such as with default ACLs.
 (ee6936da-0ddd-11ef-9c21-901b0e9408dc)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
