- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
Japan's IPA issued an alert for three vulnerabilities affecting I-O Data's UD-LT1 and UD-LT1/EX hybrid LTE routers: improper access control (CVE-2024-45841), OS command injection (CVE-2024-47133), and an undocumented function (CVE-2024-52564). The advisory states that attacks exploiting these flaws have already been confirmed in the wild, and urges users to apply firmware updates and workarounds immediately.
Successful exploitation could allow an attacker to steal authentication credentials, execute arbitrary OS commands, disable the device firewall, and alter device configuration — effectively giving full remote control over the affected routers. CVE-2024-52564 (CVSS 7.5) is the most severe, followed by CVE-2024-47133 (7.2) and CVE-2024-45841 (6.5). Fixes for the access control and command injection issues are available in firmware version 2.2.0 for both affected models; a separate fix version addresses the undocumented function vulnerability.
Given the confirmed in-the-wild exploitation against internet-facing consumer/SOHO network hardware, administrators of these devices should prioritize firmware updates and review device configurations for unauthorized changes, particularly disabled firewall settings.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it 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.
