IPA (Information-technology Promotion Agency, Japan) issued an alert regarding multiple vulnerabilities in Century Systems' FutureNet NXR and WXR series VPN routers and the VXR series virtual software router. If exploited, these flaws could allow unrestricted access via Telnet, execution of arbitrary OS commands, and theft of sensitive information from affected devices.
The advisory notes these devices are often deployed as VPN endpoints replacing legacy ISDN lines, and are frequently unmanaged as IT assets, increasing the risk that vulnerable units remain unpatched and exposed to the internet. IPA warns that successful exploitation could lead not only to compromise of the owning organization's network but also to the device being repurposed as an Operational Relay Box (ORB), unwittingly facilitating attacks against third-party organizations — a pattern previously observed with other vendors' IoT routers.
IPA recommends organizations verify whether they use the affected FutureNet product lines, apply firmware updates provided by Century Systems, and consider using services like SHODAN to identify exposed IoT/router assets. Some affected product lines have reached end-of-support status, and the vendor recommends discontinuing use or migrating to successor products for those devices.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
