CVE-2020-10282 describes a critical authentication bypass vulnerability within the MAVLink protocol, specifically versions 1.0. The absence of authentication mechanisms allows attackers to impersonate devices, gain unauthorized access to systems, and potentially execute Man-in-the-Middle (PITM) attacks. This vulnerability affects MAVLink versions 1.0–v1.0, and a fix is available by upgrading to version 2.0.
The lack of authentication in MAVLink 1.0 creates a significant attack surface. An attacker can easily spoof the identity of a legitimate drone or ground station, injecting malicious commands and potentially taking control of the system. This could lead to unauthorized flight operations, data theft, or even physical damage. Furthermore, the absence of authorization means an attacker can access and modify data without any checks, leading to a complete compromise of the MAVLink network. The potential for PITM attacks is particularly concerning, as attackers can intercept and manipulate communications between devices, further escalating the impact.
CVE-2020-10282 is not currently listed on CISA KEV. The EPSS score is likely to be medium to high, given the ease of exploitation and the potential impact on critical systems. Public proof-of-concept exploits are known to exist, demonstrating the feasibility of identity spoofing and command injection. The vulnerability was publicly disclosed on 2020-07-03.
Organizations and individuals utilizing drones, robotics, or other unmanned aerial vehicles (UAVs) that rely on MAVLink 1.0 for communication are at risk. This includes hobbyists, researchers, and commercial operators. Systems with legacy MAVLink 1.0 implementations and those lacking robust network security controls are particularly vulnerable.

The primary mitigation for CVE-2020-10282 is to upgrade to MAVLink version 2.0, which optionally includes package signing. However, it's crucial to understand that MAVLink 2.0's authentication is based on HMAC and requires careful key management – all devices must share the same symmetric key. If this isn't possible, implement network segmentation to isolate MAVLink communications. Consider using a firewall to restrict access to the MAVLink port (typically 14550) and only allow connections from trusted devices. Additionally, implement intrusion detection systems (IDS) to monitor for suspicious MAVLink traffic. After upgrading, verify the new version by attempting to send and receive commands and confirming that authentication is enforced.
Actualice a la versión 2.0 del protocolo MAVLink, que incluye soporte opcional para la firma de paquetes. Tenga en cuenta que la implementación de la versión 2.0 requiere la gestión cuidadosa de claves simétricas en todos los dispositivos de la red para evitar vulnerabilidades si una clave se ve comprometida.
