CVE-2019-12789 (GCVE-0-2019-12789)

Vulnerability from cvelistv5 – Published: 2019-06-17 16:19 – Updated: 2024-08-04 23:32

Summary

An issue was discovered on Actiontec T2200H T2200H-31.128L.08 devices, as distributed by Telus. By attaching a UART adapter to the UART pins on the system board, an attacker can use a special key sequence (Ctrl-\) to obtain a shell with root privileges. After gaining root access, the attacker can mount the filesystem read-write and make permanent modifications to the device including bricking of the device, disabling vendor management of the device, preventing automatic upgrades, and permanently installing malicious code on the device.
