CVE-2024-46450
📋 TL;DR
This vulnerability allows attackers to bypass authentication on Tenda AC1200 routers by sending specially crafted web requests. Attackers could gain unauthorized access to the router's administrative interface. This affects users running vulnerable firmware versions on the specified router model.
💻 Affected Systems

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative control of the router, enabling them to intercept traffic, modify DNS settings, install malware, or pivot to internal networks.
Likely Case
Attackers access router settings to change configurations, monitor network traffic, or perform man-in-the-middle attacks.
If Mitigated
With proper network segmentation and firewall rules, impact is limited to the router itself rather than the entire network.
🎯 Exploit Status
Exploitation requires crafting specific web requests but no authentication is needed once the vulnerability is triggered.
