Neatorobotics

An issue was discovered in Neato Botvac Connected 2.2.0. The GenerateRobotPassword function of the NeatoCrypto library generates insufficiently random numbers for robot secret_key values used for local and cloud authentication/authorization. If an attacker knows the serial number and is able to estimate the time of first provisioning of a robot, he is able to brute force the generated secret_key of the robot. This is because the entropy of the secret_key exclusively relies on these two values, due to not seeding the random generator and using several constant inputs for secret_key computation. Serial numbers are printed on the packaging and equal the MAC address of the robot.Show less

A Buffer Overflow in Network::AuthenticationClient::VerifySignature in /bin/astro in Neato Botvac Connected 2.2.0 allows a remote attacker to execute arbitrary code with root privileges via a crafted POST request to a vendors/neato/robots/[robot_serial]/messages Neato cloud URI on the nucleo.neatocloud.com web site (port 4443).Show less

Secure boot bypass and memory extraction can be achieved on Neato Botvac Connected 2.2.0 devices. During startup, the AM335x secure boot feature decrypts and executes firmware. Secure boot can be bypassed by starting with certain commands to the USB serial port. Although a power cycle occurs, this does not completely reset the chip: memory contents are still in place. Also, it restarts into a boot menu that enables XMODEM upload and execution of an unsigned QNX IFS system image, thereby completing the bypass of secure boot. Moreover, the attacker can craft custom IFS data and write it to unused memory to extract all memory contents that had previously been present. This includes the original firmware and sensitive information such as Wi-Fi credentials.Show less

A command injection vulnerability in the setup API in the Neato Botvac Connected 2.2.0 allows network attackers to execute arbitrary commands via shell metacharacters in the ntp field within JSON data to the /robot/initialize endpoint.Show less

An issue was discovered on Neato Botvac Connected 2.2.0 devices. They execute unauthenticated manual drive commands (sent to /bin/webserver on port 8081) if they already have an active session. Commands like forward, back, arc-left, arc-right, pivot-left, and pivot-right are executed even though the web socket replies with { "message" : "invalid authorization header" }. Without an active session, commands are still interpreted, but (except for eco-on and eco-off) have no effect, since without active driving, a driving direction does not change anything.Show less

An issue was discovered on Neato Botvac Connected 2.2.0 and Botvac 85 1.2.1 devices. Static encryption is used for the copying of so-called "black box" logs (event logs and core dumps) to a USB stick. These logs are RC4-encrypted with a 9-character password of *^JEd4W!I that is obfuscated by hiding it within a custom /bin/rc4_crypt binary.Show less

A replay issue was discovered on Neato Botvac Connected 2.2.0 devices. Manual control mode requires authentication, but once recorded, the authentication (always transmitted in cleartext) can be replayed to /bin/webserver on port 8081. There are no nonces, and timestamps are not checked at all.Show less
