EUVD-2023-35507

Comprehensive Technical Analysis of EUVD-2023-35507

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2023-35507 affects the DroneScout ds230 Remote ID receiver from BlueMark Innovations. This vulnerability allows an attacker to inject high-power spoofed Open Drone ID (ODID) messages, causing the receiver to drop real Remote ID (RID) information and instead transmit crafted RID information via JSON encoded MQTT messages.

Severity Evaluation:

• CVSS Base Score: 9.3
• CVSS Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H

The high CVSS score indicates a critical vulnerability. The attack vector (AV:A) suggests that the attacker needs to be adjacent to the target, but the low attack complexity (AC:L) and the lack of required privileges (PR:N) or user interaction (UI:N) make it easier to exploit. The impact on integrity (I:H) and availability (A:H) is high, while the confidentiality impact (C:N) is none. The scope change (S:C) indicates that the vulnerability affects a component that is outside the security scope of the vulnerable component.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Traffic Injection: An attacker can inject high-power spoofed ODID messages on carefully selected channels.
2. Adjacent Channel Suppression Algorithm Exploitation: The vulnerability exploits weaknesses in the adjacent channel suppression algorithm, causing the receiver to drop real RID information.

Exploitation Methods:

1. Spoofed ODID Messages: Craft and transmit high-power ODID messages to overwhelm the receiver.
2. MQTT Message Manipulation: Force the receiver to generate and transmit JSON encoded MQTT messages containing crafted RID information.

3. Affected Systems and Software Versions

Affected Systems:

• DroneScout ds230 Remote ID receiver

Affected Software Versions:

• Firmware versions from 20211210-1627 through 20230329-1042

4. Recommended Mitigation Strategies

1. Firmware Update: Ensure that the DroneScout ds230 firmware is updated to a version that addresses this vulnerability.
2. Signal Monitoring: Implement monitoring systems to detect and alert on unusual signal patterns that may indicate spoofed ODID messages.
3. Access Control: Restrict physical access to the DroneScout ds230 receiver to prevent adjacent attacks.
4. MQTT Broker Security: Enhance the security of the MQTT broker to detect and filter out crafted RID information.
5. Network Segmentation: Segment the network to limit the impact of compromised devices.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to the European cybersecurity landscape, particularly in sectors that rely on drone technology for critical operations such as surveillance, logistics, and emergency services. The ability to spoof RID information can lead to misinformation, operational disruptions, and potential safety risks. This underscores the need for robust cybersecurity measures in drone technology and the importance of timely vulnerability disclosure and patching.
