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.
The product uses a transmission protocol that does not include a mechanism for verifying the integrity of the data during transmission, such as a checksum.
