What it is

🔥 A sneaky stack overflow is hiding in the Tenda TX3, lurking just behind the endIp parameter at /goform/SetPptpServerCfg! Think of it as a restaurant that serves an extra-large portion when you only ordered a small. If the kitchen doesn't have proper limits on servings, it could overflow and cause chaos in the dining room! An attacker could exploit this stack overflow to crash the system, or worse, execute arbitrary code remotely. This means they could gain control over the device and potentially access your network – an absolutely devastating scenario!
