### POCs of the modem:

### Conclusion: 
1)the attacker can read sensitive information and set it on his own modem. such: for using free internet.
2)Anyone who can send a packet to the modem for crashing/downgrading/DOS.
3)An attacker might use "Frame Injection" to redirect users to other malicious websites that are used for phishing and similar attacks.
4)To obtain the control of similar modem(LX350P) in order to launching DOS or DDOS attacks on targets in WWW(world wide web).  


At the end, I am thankful and I wait for your response.
