CVE-2026-2616 is a high severity hard-coded credentials flaw (CVSS 8.8) in the web management interface of the Beetel 777VR1 router, up to firmware 01.00.09. No vendor fix is known. Restrict access to the interface. The record says exploit details are public.
What's affected
- Beetel 777VR1 up to firmware 01.00.09
- No fixed version is known
The record says the vendor was contacted early and did not respond. It says the attack must start from the local network. A public write-up tests firmware V01.00.09 and V01.00.09_55 only, so other versions are unverified.
How to check if you're exposed
Find the router model and firmware version in its administration page or label. If it is a 777VR1 at 01.00.09 or earlier, treat it as affected. Then find out who on the local network can reach the management interface, including guest Wi-Fi and any device that has been compromised. This is a local network attack, so the people and devices on the LAN are the exposure.
What to do now
- Change the administration settings and password as the record advises, using a long unique password.
- Turn off remote management and make sure the web interface is not reachable from the internet.
- Move untrusted devices, such as guests and smart home gadgets, to a separate network.
- Ask the provider or manufacturer about a replacement or newer firmware.
- Replace the router if no fix appears and it protects anything that matters.
Why it matters
CWE-259 and CWE-798 are the use of a hard-coded password and hard-coded credentials. A secret baked into a product is shared by every device of that model, so once it is known, it opens all of them. The public write-up also reports no limit on login attempts, which relates to CWE-307, though the record lists only the first two classes.
Home and small office routers are a recurring source of this problem. They are rarely updated, sit at the edge of the network, and control the traffic of everything behind them. Control of the router means the ability to change DNS settings and watch or redirect traffic.
Because the vendor has not responded, the realistic choices are to contain the exposure or replace the device.
Quick check
Can I patch it?
No fix is known. The record says the vendor did not respond.
Is the attack remote over the internet?
The record says it must be started from the local network, so remote management and local access are the things to lock down.
