Sunway ForceControl is a Chinese SCADA/HMI software application widely used in China to help run weapons systems, utilities and chemical plants. It is also used to a lesser extent in other countries, including the US. SNMP NetDBServer is one of the components of this application.


SNMP NetDBServer is vulnerable to a stack buffer overflow as a result of copying data chunks in a stack buffer. This vulnerability can be exploited by a malicious user sending a specially crafted request to SNMP NetDBServer on port 2001/tcp.
