What it is

⚠️ An unauthenticated attacker can change your admin password in seconds, thanks to a hidden command in Trendnet's firmware! Think of it like having a secret door in a restaurant’s kitchen that any customer can slip through — they could rearrange the menu or even lock the chefs out! This flaw gives attackers direct access to your device’s settings without ever having to place a legit order. If exploited, a malicious actor could take full control of your router, potentially opening the door to a host of security breaches, such as spying on your network traffic or redirecting your traffic. This could lead to compromised devices and stolen personal information — absolutely devastating!
