⚡ A simple crafted SSID can trigger a stack overflow! The Totolink LR350 is vulnerable, and that means a Denial of Service could be just a request away! 🔥 Think of the router as a restaurant where the chef can only handle a certain number of orders at once. If a customer sends an order that’s too big, the kitchen gets overwhelmed, and everyone is left hungry — that’s what happens here with a runaway request! An attacker could exploit this vulnerability to overwhelm the router, causing it to crash and deny service to all users. This could leave your network unresponsive, cutting off internet access for everyone connected, which is absolutely devastating!
Think of the router as a restaurant where the chef can only handle a certain number of orders at once. If a customer sends an order that’s too big, the kitchen gets overwhelmed, and everyone is left hungry — that’s what happens here with a runaway request! This stack overflow vulnerability occurs in the Totolink LR350 when the `ssid` parameter is mishandled in the `sub_42396C` function, allowing an attacker to send a crafted request that leads to a Denial of Service condition.
An attacker could exploit this vulnerability to overwhelm the router, causing it to crash and deny service to all users. This could leave your network unresponsive, cutting off internet access for everyone connected, which is absolutely devastating!
