⚠️ A stack overflow lurking in Tenda AX3 could turn your router into a no-show! 🚫 Think of it like a restaurant where the kitchen can’t handle a sudden surge of orders — more and more requests pile up until everything comes to a complete halt. That’s exactly what's happening here with the time parameter! An attacker could send a specially crafted time request, causing the system to overload and leading to a Denial of Service (DoS). This means your network might come to a standstill, leaving you unable to browse or use connected devices, which can be absolutely frustrating!
