TITLE

Moxa NPort5110 TCP / IP Stack Denial of Service Vulnerability

Trust: 0.6

sources: CNVD: CNVD-2016-12094

DESCRIPTION

Moxa NPort5110 is an industrial-grade serial server produced by Taiwan's Moxa Corporation. It is used for serial device networking. A denial of service vulnerability exists in the Moxa NPort5110 TCP / IP protocol stack. Sending 1-2 UDP abnormal packets to the UDP port 161 (SNMP) of the NPort5110 can cause the TCP / IP protocol stack of the NPort5110 to crash and the device to fail to respond. The device must be powered off and restarted. An attacker could exploit the vulnerability to launch a denial of service attack.
