Visual Components (owned by KUKA) is a robotic simulator that allows simulating factories and robots in order toimprove planning and decision-making processes. Visual Components software requires a special license which can beobtained from a network license server. The network license server binds to all interfaces (0.0.0.0) and listensfor packets over UDP port 5093. No authentication/authorization is required in order to communicate with theserver. The protocol being used is a property protocol by RMS Sentinel which provides the licensing infrastructurefor the network license server. RMS Sentinel license manager service exposes UDP port 5093 which provides sensitivesystem information that could be leveraged for further exploitation without any kind of authentication. Thisinformation includes detailed hardware and OS characteristics.After a decryption process, a textual protocol is found which contains a simple header with the requested command,application-identifier, and some arguments. The protocol leaks information regarding the receiving serverinformation, license information and managing licenses, among others.Through this flaw, attackers can retreive information about a KUKA simulation system, particularly, the version ofthe licensing server, which is connected to the simulator, and which will allow them to launch local simulationswith similar characteristics, further understanding the dynamics of motion virtualization and opening doors toother attacks (see RVDP#711 and RVDP#712 for subsequent vulnerabilities that compromise integrity andavailability).Beyond compromising simulations, Visual Components provides capabilities to interface with industrial machinery.Particularly, their PLC Connectivity feature 'makes it easy' to connect simulations with control systems usingeither the industry standard OPC UA or other supported vendor specific interfaces. This fills the gap of jumpingfrom simulation to real and enables attackers to pivot from the Visual Components simulator to robots or otherIndustrial Control System (ICS) devices, such as PLCs.

Universal Robots controller execute URCaps (zip files containing Java-powered applications) without any permission restrictions and a wide API that presents many primitives that can compromise the overall robot operations as demonstrated in our video. In our PoC we demonstrate how a malicious actor could 'cook' a custom URCap that when deployed by the user (intendedly or unintendedly) compromises the system

The Micro Air Vehicle Link (MAVLink) protocol presents authentication mechanisms on its version 2.0 however according to its documentation, in order to maintain backwards compatibility, GCS and autopilot negotiate the version via the AUTOPILOT_VERSION message. Since this negotiation depends on the answer, an attacker may craft packages in a way that hints the autopilot to adopt version 1.0 of MAVLink for the communication. Given the lack of authentication capabilities in such version of MAVLink (refer to CVE-2020-10282), attackers may use this method to bypass authentication capabilities and interact with the autopilot directly.

IRC5 exposes an ftp server (port 21). Upon attempting to gain access you are challenged with a request of username and password, however you can input whatever you like. As long as the field isn't empty it will be accepted.

The IRC5 family with UAS service enabled comes by default with credentials that can be found on publicly available manuals. ABB considers this a well documented functionality that helps customer set up however, out of our research, we found multiple production systems running these exact default credentials and consider thereby this an exposure that should be mitigated. Moreover, future deployments should consider that these defaults should be forbidden (user should be forced to change them).

the main user account has restricted privileges but is in the sudoers group and there is not any mechanism in place to prevent sudo su or sudo -i to be run gaining unrestricted access to sensible files, encryption, or issue orders that disrupt robot operation.

The authentication implementation on the xArm controller has very low entropy, making it vulnerable to a brute-force attack. There is no mechanism in place to mitigate or lockout automated attempts to gain access.

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 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.

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.

MiR controllers across firmware versions 2.8.1.1 and before do not encrypt or protect in any way the intellectual property artifacts installed in the robots. This flaw allows attackers with access to the robot or the robot network (while in combination with other flaws) to retrieve and easily exfiltrate all installed intellectual property and data.

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.

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 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.

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.

MiR100, MiR200 and other MiR robots use the Robot Operating System (ROS) default packages exposing the computational graph to all network interfaces, wireless and wired. This is the result of a bad set up and can be mitigated by appropriately configuring ROS and/or applying custom patches as appropriate. Currently, the ROS computational graph can be accessed fully from the wired exposed ports. In combination with other flaws such as CVE-2020-10269, the computation graph can also be fetched and interacted from wireless networks. This allows a malicious operator to take control of the ROS logic and correspondingly, the complete robot given that MiR's operations are centered around the framework (ROS).

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.

One of the wireless interfaces within MiR100, MiR200 and possibly (according to the vendor) other MiR fleet vehicles comes pre-configured in WiFi Master (Access Point) mode. Credentials to such wireless Access Point default to well known and widely spread SSID (MiR_RXXXX) and passwords (omitted). This information is also available in past User Guides and manuals which the vendor distributed. We have confirmed this flaw in MiR100 and MiR200 but it might also apply to MiR250, MiR500 and MiR1000.

Critical services for operation can be terminated from windows task manager, bringing the manipulator to a halt. After this a Re-Calibration of the brakes needs to be performed. Be noted that this only can be accomplished either by a Kuka technician or by Kuka issued calibration hardware that interfaces with the manipulator furthering the delay and increasing operational costs.

Universal Robots control box CB 3.1 across firmware versions (tested on 1.12.1, 1.12, 1.11 and 1.10) does not encrypt or protect in any way the intellectual property artifacts installed from the UR+ platform of hardware and software components (URCaps). These files (*.urcaps) are stored under '/root/.urcaps' as plain zip files containing all the logic to add functionality to the UR3, UR5 and UR10 robots. This flaw allows attackers with access to the robot or the robot network (while in combination with other flaws) to retrieve and easily exfiltrate all installed intellectual property.

UR+ (Universal Robots+) is a platform of hardware and software component sellers, for Universal Robots robots. When installing any of these components in the robots (e.g. in the UR10), no integrity checks are performed. Moreover, the SDK for making such components can be easily obtained from Universal Robots. An attacker could exploit this flaw by crafting a custom component with the SDK, performing Person-In-The-Middle attacks (PITM) and shipping the maliciously-crafted component on demand.

SROS 2 0.8.1 (which provides the tools that generate and distribute keys for Robot Operating System 2 and uses the underlying security plugins of DDS from ROS 2) leaks node information due to a leaky default configuration as indicated in the policy/defaults/dds/governance.xml document.

SROS 2 0.8.1 (after CVE-2019-19625 is mitigated) leaks ROS 2 node-related information regardless of the rtps_protection_kind configuration. (SROS2 provides the tools to generate and distribute keys for Robot Operating System 2 and uses the underlying security plugins of DDS from ROS 2.)
