Description

Some Linksys Routers are vulnerable to an authenticated OS command injection in
the Web Interface. Default credentials are admin/admin or admin/password. 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. The user must be prudent when using this
module since it modifies the router configuration while exploitation, even when it
tries to restore previous values.
