A line of routers from a China-based manufacturer has a serious flaw that could allow a hacker to access the device. The Netcore and Netis routers have an open UDP port, 53413, which can be queried. The password needed to open up the backdoor is hardcoded into the device’s firmware. Trend Micro has notified the company but did not receive a response. Company officials reached in Shenzhen, China, didn’t have an immediate comment on the flaw, according to Trend Micro.”]
