Description

Some Linksys Routers are vulnerable to an authenticated OS command injection on
their web interface where 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. This module has been tested on
a Linksys WRT160n version 2 - firmware version v2.0.03. A ping command against a
controlled system could be used for testing purposes. The exploit uses the tftp
client from the device to stage to native payloads from the command injection.
