Linksys WRT54GL apply.cgi Command Execution

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.
