CVE-2017-5544

CVE-2017-5544 describes a denial-of-service condition in FiberHome Fengine S5800 switches running V210R240. An attacker who can reach the SSH service can make repeated login attempts, causing SSH login timeouts to increase and connection slots to remain occupied longer. When that happens, legitimate SSH and telnet logins can be refused, and the device may need a restart to recover.
