Linksys WRT160nv2 apply.cgi Remote Command Injection

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.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
