Local Arbitrary Code Execution via Unprotected UART Interface on Mercusys AC12 V2

An issue in Mercusys AC12 V2 allows a local attacker to execute arbitrary code via the UART serial interface on the printed circuit board (PCB)

Intel (R): From CVEorg collector

Missing protection mechanism for alternate hardware interface in the Intel(R) Quick Assist Technology for some Intel(R) Platforms within Ring 0: Kernel may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Access to Bootloader and Shell Over Serial Interface

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.

Panasonic IR Control Hub (IR Blaster) versions 1.17 and earlier may allow an attacker with physical access to load unauthorized firmware onto the device.

Missing Protection Mechanism for Alternate Hardware Interface

The device directly executes .patch firmware upgrade files on a USB stick without any prior authentication in the admin interface. This leads to an unauthenticated code execution via the firmware upgrade function.

Lack of DMA Access Protections

The FACSChorus workstation does not prevent physical access to its PCI express (PCIe) slots, which could allow a threat actor to insert a PCI card designed for memory capture. A threat actor can then isolate sensitive information such as a BitLocker encryption key from a dump of the workstation RAM during startup.

Shell access to UART Console

An attacker can use an undocumented UART port on the PCB as a side-channel to get root access e.g. with the credentials obtained from CVE-2025-41692.

Lack of USB Whitelisting

The FACSChorus workstation operating system does not restrict what devices can interact with its USB ports. If exploited, a threat actor with physical access to the workstation could gain access to system information and potentially exfiltrate data.

BD BodyGuard™ Pumps – RS-232 Interface Vulnerability

The BD BodyGuard™ infusion pumps specified allow for access through the RS-232 (serial) port interface. If exploited, threat actors with physical access, specialized equipment and knowledge may be able to configure or disable the pump. No electronic protected health information (ePHI), protected health information (PHI) or personally identifiable information (PII) is stored in the pump.

IBM FlashSystem denial of service

IBM FlashSystem 5300 USB ports may be usable even if the port has been disabled by the administrator. A user with physical access to the system could use the USB port to cause loss of access to data. IBM X-Force ID: 295935.

An exposed debug interface was reported in some Motorola-branded Binatone Hubble Cameras that could allow an attacker with physical access unauthorized access to the device.
