CVE-2026-2618Medium

This vulnerability allows an attacker to potentially exploit the SSH service on Beetel 777VR1 routers, which could lead to the use of weak cryptographic methods, compromising the security of communications. Although the attack can be done remotely, it is complex and difficult to execute, and the vendor has not responded to reports about the issue.

CVE-2026-2616High

This vulnerability allows an attacker on the same local network to access the web management interface of the Beetel 777VR1 router using hard-coded credentials, which could give them full control over the device. Since the exploit requires local network access, it poses a risk primarily in environments where unauthorized users can connect to the network.
