🚨 One sneaky command injection hides in Tenda routers G1 and G3, allowing attackers to run arbitrary commands through the hostName parameter. 😱 It's like giving a stranger the ability to send any message they want to your smart home system — if they know the right phrase, they can open your doors or adjust your thermostat without your knowledge! An attacker could essentially take control of your router, leading to unauthorized access to your network and potential data breaches. This could compromise sensitive information and even allow for follow-on attacks within your internal environment.
