Vulnerability from fkie_nvd - Published: 2020-09-25 04:23 - Updated: 2026-06-17 03:07
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
The Telnet service of Rubetek cameras RV-3406, RV-3409, and RV-3411 cameras (firmware versions v342, v339) could allow an remote attacker to take full control of the device with a high-privileged account. The vulnerability exists because a system account has a default and static password. The Telnet service cannot be disabled and this password cannot be changed via standard functionality.
