CVE-2026-2618Public exploitNetwork attack vector

SSH session disclosure via obsolete cryptographic algorithms

Published Feb 17, 2026 · Updated Feb 17, 2026

Cryptographic weakness in Beetel 777VR1 firmware 01.00.09 and 01.00.09_55 allows remote attackers to expose SSH session data. The SSH daemon identifies as SSH_0.48 and negotiates diffie-hellman-group1-sha1, SHA-1 ssh-rsa host keys, and 3des-cbc instead of modern primitives. Reachability requires a network position capable of intercepting SSH management traffic; the demonstrated consequence is confidentiality loss, not direct device takeover.
