A vulnerability exists in serial device servers where active debug code remains enabled in the UART interface. An attacker with physical access to the device can directly connect to the UART interface and, without authentication, user interaction, or execution conditions, gain unauthorized access to internal debug functionality. Exploitation is low complexity and allows an attacker to execute privileged operations and access sensitive system resources, resulting in a high impact to the confidentiality, integrity, and availability of the affected device. No security impact to external or dependent systems has been identified.

Affected devices do not properly limit access to a development shell accessible over a physical interface. This could allow an unauthenticated attacker with physical access to the device to execute arbitrary commands on the device.
Smart-tab Android app installed April 2023 or earlier contains an active debug code vulnerability. If this vulnerability is exploited, an attacker with physical access to the device may exploit the debug function to gain access to the OS functions, escalate the privilege, change the device's settings, or spoof devices in other rooms.
A vulnerability was found in Netis WF-2404 1.1.124EN. It has been declared as critical. This vulnerability affects unknown code of the component UART. The manipulation leads to hardware allows activation of test or debug logic at runtime. It is possible to launch the attack on the physical device. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
