CVE’s

The Micro Air Vehicle Link (MAVLink) protocol presents no authentication mechanism on its version 1.0 (nor authorization) whichs leads to a variety of attacks including identity spoofing, unauthorized access, PITM attacks and more. According to literature, version 2.0 optionally allows for package signing which mitigates this flaw. Another source mentions that MAVLink 2.0 only provides a simple authentication system based on HMAC. This implies that the flying system overall should add the same symmetric key into all devices of network. If not the case, this may cause a security issue, that if one of the devices and its symmetric key are compromised, the whole authentication system is not reliable.

This vulnerability applies to the Micro Air Vehicle Link (MAVLink) protocol and allows a remote attacker to gain access to sensitive information provided it has access to the communication medium. MAVLink is a header-based protocol that does not perform encryption to improve transfer (and reception speed) and efficiency by design. The increasing popularity of the protocol (used accross different autopilots) has led to its use in wired and wireless mediums through insecure communication channels exposing sensitive information to a remote attacker with ability to intercept network traffic.

The Apache server on port 80 that host the web interface is vulnerable to a DoS by spamming incomplete HTTP headers, effectively blocking the access to the dashboard.

A memory corruption vulnerability exists when Windows Media Foundation improperly handles objects in memory, aka 'Media Foundation Memory Corruption Vulnerability'. This CVE ID is unique from CVE-2020-1126, CVE-2020-1136, CVE-2020-1150.

MiR robot controllers (central computation unit) makes use of Ubuntu 16.04.2 an operating system, Thought for desktop uses, this operating system presents insecure defaults for robots. These insecurities include a way for users to escalate their access beyond what they were granted via file creation, access race conditions, insecure home directory configurations and defaults that facilitate Denial of Service (DoS) attacks.

The BIOS onboard MiR's Computer is not protected by password, therefore, it allows a Bad Operator to modify settings such as boot order. This can be leveraged by a Malicious operator to boot from a Live Image.

There is no mechanism in place to prevent a bad operator to boot from a live OS image, this can lead to extraction of sensible files (such as the shadow file) or privilege escalation by manually adding a new user with sudo privileges on the machine.

The password for the safety PLC is the default and thus easy to find (in manuals, etc.). This allows a manipulated program to be uploaded to the safety PLC, effectively disabling the emergency stop in case an object is too close to the robot. Navigation and any other components dependent on the laser scanner are not affected (thus it is hard to detect before something happens) though the laser scanner configuration can also be affected altering further the safety of the device.

The access tokens for the REST API are directly derived from the publicly available default credentials for the web interface. Given a USERNAME and a PASSWORD, the token string is generated directly with base64(USERNAME:sha256(PASSWORD)). An unauthorized attacker inside the network can use the default credentials to compute the token and interact with the REST API to exfiltrate, infiltrate or delete data.

The access tokens for the REST API are directly derived (sha256 and base64 encoding) from the publicly available default credentials from the Control Dashboard (refer to CVE-2020-10270 for related flaws). This flaw in combination with CVE-2020-10273 allows any attacker connected to the robot networks (wired or wireless) to exfiltrate all stored data (e.g. indoor mapping images) and associated metadata from the robot's database.
