VAR-201701-0735
Vulnerability from variot - Updated: 2025-04-20 23:34An issue was discovered on FiberHome Fengine S5800 switches V210R240. An unauthorized attacker can access the device's SSH service, using a password cracking tool to establish SSH connections quickly. This will trigger an increase in the SSH login timeout (each of the login attempts will occupy a connection slot for a longer time). Once this occurs, legitimate login attempts via SSH/telnet will be refused, resulting in a denial of service; you must restart the device. FiberHome Fengine S5800 Switch has service disruption ( Reboot device ) There are vulnerabilities that are put into a state.An unauthenticated attacker SSH Service access is disrupted by accessing the service ( Reboot device ) There is a possibility of being put into a state. FiberHomeFengineS5800Switches is a new generation of Gigabit routing switches designed to meet multi-service access and high-density aggregation. The series of router switches are equipped with high-density Gigabit ports and 10 Gigabit uplinks, which can meet various applications such as broadband metropolitan area network, enterprise network, WLAN aggregation, and campus networking. A remote denial of service vulnerability exists in FiberHomeFengineS5800Switches
