CVE-2025-48468

Open JTAG Debug Port

CVSS 6.4 MEDIUMEPSS 0.2%CWE-1191
In short

A JTAG debug port is left open and unprotected on the device. An attacker with physical access can use this port to inject or change the device's firmware, potentially taking complete control of it.

Technical detail

The JTAG interface lacks authentication or access controls, allowing an attacker with physical proximity to the device to read, modify, or inject firmware through the debug port. This requires physical access but can result in persistent compromise of the device's integrity and functionality.

Summary generated and translated by AI from the official description.
Successful exploitation of the vulnerability could allow an attacker that has physical access to interface with JTAG to inject or modify firmware.
CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
