📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full router compromise allowing attacker to install persistent backdoors, intercept all network traffic, pivot to internal networks, or brick the device.
Likely Case
Router takeover enabling traffic monitoring, DNS hijacking, credential theft, and lateral movement to connected devices.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to router admin interface.
🎯 Exploit Status
Public proof-of-concept exists in GitHub repository. Exploitation requires authentication but is straightforward once authenticated.
