Mesh Firmware

An issue was discovered on goTenna Mesh devices with app 5.5.3 and firmware 1.1.12. It uses a custom implementation of encryption without any additional integrity checking mechanisms. This leaves messages malleable to an attacker that can access the message.Show less

An issue was discovered on goTenna v1 devices with app 5.5.3 and firmware 0.25.5. All packets sent over RF are also sent over UART with USB Shell, allowing someone with local access to gain information about the protocol and intercept sensitive data.Show less

An issue was discovered on goTenna v1 devices with app 5.5.3 and firmware 0.25.5. The app there makes it possible to inject any custom message (into existing v1 networks) with any GID and Callsign via a software defined radio. This can be exploited if the device is being used in an unencrypted environment or if the cryptography has already been compromised.Show less

An issue was discovered on goTenna Mesh devices with app 5.5.3 and firmware 1.1.12. By default, a GID is the user's phone number unless they specifically opt out. A phone number is very sensitive information because it can be tied back to individuals. The app does not encrypt the GID in messages.Show less
