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. Several products contain vulnerabilities in the use of hard-coded credentials.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state

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. Information leakage vulnerabilities exist in multiple products.Information may be obtained and tampered with

MiR100, MiR200 and other MiR robots use the Robot Operating System (ROS) default packages exposing the computational graph without any sort of authentication. This allows attackers with access to the internal wireless and wired networks to take control of the robot seamlessly. In combination with CVE-2020-10269 and CVE-2020-10271, this flaw allows malicious actors to command the robot at desire. plural MiR The product contains vulnerabilities related to lack of authentication for critical features.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state

Out of the wired and wireless interfaces within MiR100, MiR200 and other vehicles from the MiR fleet, it's possible to access the Control Dashboard on a hardcoded IP address. Credentials to such wireless interface default to well known and widely spread users (omitted) and passwords (omitted). This information is also available in past User Guides and manuals which the vendor distributed. This flaw allows cyber attackers to take control of the robot remotely and make use of the default user interfaces MiR has created, lowering the complexity of attacks and making them available to entry-level attackers. More elaborated attacks can also be established by clearing authentication and sending network requests directly. We have confirmed this flaw in MiR100 and MiR200 but according to the vendor, it might also apply to MiR250, MiR500 and MiR1000. plural MiR The product contains a vulnerability in the use of hard-coded credentials.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state
