- CWE-1191 - On-Chip Debug and Test Interface With Improper Access Control
Summary
A vulnerability was determined in TOZED ZLT M30s up to 1.47. The affected element is an unknown function of the component UART Interface. Executing manipulation can lead to on-chip debug and test interface with improper access control. The physical device can be targeted for the attack. Attacks of this nature are highly complex. The exploitability is described as difficult. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

Summary
A serial interface can be accessed with physical access to the PCB of Wattsense Bridge devices. After connecting to the interface, access to the bootloader is possible, as well as a Linux login prompt. The bootloader access can be used to gain a root shell on the device. This issue is fixed in recent firmware versions BSP >= 6.4.1.

Summary
The CleverDisplay BlueOne hardware player is designed with its USB interfaces physically enclosed and inaccessible under normal operating conditions. Researchers demonstrated that, after cicumventing the device’s protective enclosure, it was possible to connect a USB keyboard and press ESC during boot to access the BIOS setup interface. BIOS settings could be viewed but not modified. This behavior slightly increases the attack surface by exposing internal system information (CWE-1244) once the enclosure is removed, but does not allow integrity or availability compromise under standard or tested configurations.

Mitigation
Phase: Architecture and Design
Strategy: Separation of Privilege
Description:
- If feasible, the manufacturer should disable the JTAG interface or implement authentication and authorization for the JTAG interface. If authentication logic is added, it should be resistant to timing attacks. Security-sensitive data stored in registers, such as keys, etc. should be cleared when entering debug mode.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
CAPEC-180: Exploiting Incorrectly Configured Access Control Security Levels
An attacker exploits a weakness in the configuration of access controls and is able to bypass the intended protection that these measures guard against and thereby obtain unauthorized access to the system or network. Sensitive functionality should always be protected with access controls. However configuring all but the most trivial access control systems can be very complicated and there are many opportunities for mistakes. If an attacker can learn of incorrectly configured access security settings, they may be able to exploit this in an attack.
