An issue in Netcore B11 Enterprise-level full Gigabit 9-port shop wireless router v1.3.241114.024540 and before allows a remote attacker to execute arbitrary code via the www\cgi-bin\upgrade file

A flaw has been found in Netcore NR268 1.7.121109. The affected element is the function execvp of the file /router/DDNSset.cgi of the component DDNS. Executing a manipulation of the argument Hostname can lead to argument injection. The attack can be launched remotely.

A remote code execution vulnerability exists in multiple Netcore and Netis routers models with firmware released prior to August 2014 due to the presence of an undocumented backdoor listener on UDP port 53413. Exact version boundaries remain undocumented. An unauthenticated remote attacker can send specially crafted UDP packets to execute arbitrary commands on the affected device. This backdoor uses a hardcoded authentication mechanism and accepts shell commands post-authentication. Some device models include a non-standard implementation of the echo command, which may affect exploitability.
