What it is

⚡ A remote attack can trigger a buffer overflow in D-Link DWR-M920 devices running up to version 1.1.50, thanks to a sneaky manipulation of the submit-url argument! 🔥 Think of it like a restaurant where customers can order anything off the menu, but the server doesn’t check if the kitchen can actually prepare it. If someone orders an outrageous dish, the kitchen might overflow with chaos! This could be absolutely devastating for your device – a remote attacker could exploit this vulnerability to execute arbitrary code, potentially taking full control of the device. Imagine your router being turned into a puppet on strings, doing whatever the attacker wishes!
