Overview
CVE-2025-63896 describes a security vulnerability found in the Bluetooth Human Interface Device (HID) functionality of the JXL 9 Inch Car Android Double Din Player running Android v12.0. This flaw allows a remote attacker to inject arbitrary keystrokes into the device via a spoofed Bluetooth HID device. This can potentially lead to unauthorized access, data manipulation, or other malicious activities within the Android system.
Technical Details
The vulnerability stems from insufficient validation of the Bluetooth HID connection and data received by the JXL Android player. An attacker within Bluetooth range can impersonate a legitimate Bluetooth HID device (such as a keyboard or mouse) and transmit malicious keystroke sequences. Because the JXL player doesn’t properly authenticate or sanitize this input, it executes the injected keystrokes as if they originated from a trusted source. This can include executing arbitrary commands, opening applications, or accessing sensitive data.
The attack requires the attacker to be within Bluetooth range of the JXL device and to be able to spoof a Bluetooth HID device. The attacker must also craft the malicious keystroke sequences.
CVSS Analysis
Currently, a CVSS score has not been assigned to CVE-2025-63896 (N/A). A proper CVSS score calculation will need to be performed to better asses the impact of the vulnerabilty, taking into consideration the attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact.
Possible Impact
The successful exploitation of CVE-2025-63896 could have several severe consequences, including:
- Unauthorized Access: The attacker could gain unauthorized access to the Android system and its settings.
- Data Theft: The attacker may be able to access and steal sensitive data stored on the device, such as contacts, messages, or saved credentials.
- Malware Installation: The injected keystrokes could be used to download and install malware on the device.
- System Manipulation: The attacker could alter system settings, disable features, or even brick the device.
- Navigation System Compromise: Depending on the level of integration, the attacker could potentially manipulate the navigation system.
Mitigation or Patch Steps
Currently, information on a patch or official mitigation from JXL is unavailable. However, the following steps are advised:
- Disable Bluetooth: If Bluetooth functionality is not essential, disable it to prevent potential attacks.
- Monitor Bluetooth Connections: Regularly review the list of paired Bluetooth devices and remove any unfamiliar or suspicious devices.
- Firmware Updates: Check for and install any available firmware updates from JXL that address this vulnerability. Visit the JXL website regularly for updates.
- Network Isolation: If possible, isolate the JXL device from other critical network segments.
