This vulnerability exists in SyroTech SY-GPON-1110-WDONT Router due to presence of root terminal access on a serial interface without proper access control. An attacker with physical access could exploit this by accessing the root shell on the vulnerable system. Successful exploitation of this vulnerability could allow the attacker to execute arbitrary commands with root privileges on the targeted system.
Solution:
The chip does not implement or does not correctly perform access control to check whether users are authorized to access internal registers and test modes through the physical debug/test interface.
