📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete router compromise allowing attackers to intercept all network traffic, install persistent malware, pivot to internal networks, and disable security features.
Likely Case
Router takeover leading to DNS hijacking, credential theft from network traffic, and deployment of botnet malware.
If Mitigated
Limited impact if backup import functionality is disabled or network segmentation isolates the router.
🎯 Exploit Status
Exploit requires authentication to access backup import feature. Public exploit code available on GitHub and Exploit-DB.
