What it is

⚠️ The WAN configuration page is open for business! On D-Link DIR-615 devices running firmware 20.06, attackers can access "wan.htm" without any authentication – and that’s just the beginning! 🔍 Think of it like a restaurant that leaves its menu out for anyone to see, but in this case, it’s not just about browsing; you could also change the orders right there! It’s like letting a customer rewrite the sushi specials without the chef's knowledge. An attacker could easily peek into sensitive WAN settings and even modify them, potentially rerouting traffic or creating a backdoor for future access. This could lead to significant network vulnerabilities, putting your entire online presence at risk!
