Moxa MAR-2000 router: admin can run commands via saved settings fields
A logged-in administrator of this industrial cellular router can hide system commands inside ordinary settings fields, and the router then runs them. Anyone who gets admin access can take over the device.

- 4Command executesRuns as the router's model process
- ResultAttacker controls the router
What happened
Three command injection flaws in Moxa MAR-2000 firmware FWR_MAR2000_V1.0_Build_15010909 allow an authenticated administrator to inject shell commands through IPsec tunnel address fields, scenario ping condition fields, and the Executer program launch path, executing them as the product's model process.
Are you affected?
You are affected if you run Moxa MAR-2000 series routers on firmware FWR_MAR2000_V1.0_Build_15010909 and have administrator accounts that could be misused.
Moxa MAR-2000 series, firmware FWR_MAR2000_V1.0_Build_15010909
What to do
