⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full router control, enabling network traffic interception, DNS hijacking, malware distribution to connected devices, and persistent backdoor installation.
Likely Case
Local network attackers compromise the router to monitor traffic, redirect users to malicious sites, or use the router as a pivot point for further attacks.
If Mitigated
With Telnet disabled and strong authentication, the router operates normally with no unauthorized access.
🎯 Exploit Status
Exploitation requires only Telnet access to router IP on port 23 with 'root' username and no password.
