CVE-2026-47116 — CRITICAL (9.8)

Vulnerability Description

LTSecurity LTK3500SF contains a hard-coded credentials vulnerability where the root and guest account passwords are stored in /etc/shadow as weak hashes recoverable with dictionary-based cracking tools. The recovered credentials authenticate against the device's Telnet and SSH services and grant root-level access to the operating system. These services are not confirmed to start automatically at boot, so exploitation requires Telnet or SSH to be running, whether enabled by the device configuration or started manually.
