Description

Some Netgear Routers are vulnerable to authenticated OS Command injection. The
vulnerability exists in the web interface, specifically in the setup.cgi component,
when handling the TimeToLive parameter. Default credentials are always a good
starting point, admin/admin or admin/password could be a first try. Since it is a
blind os command injection vulnerability, there is no output for the executed
command when using the cmd generic payload. A ping command against a controlled
system could be used for testing purposes.
