Observable Response Discrepancy in goTenna Pro
The goTenna Pro App does not inject extra characters into broadcasted frames to obfuscate the length of messages. This makes it possible to tell the length of the payload regardless of the encryption used.

Insertion of Sensitive Information Into Sent Data in goTenna Pro
The goTenna Pro App encryption key name is always sent unencrypted when the key is shared over RF through a broadcast message. It is advised to share the encryption key via local QR for higher security operations.

Weak Authentication in goTenna Pro
In the goTenna Pro App there is a vulnerability that makes it possible to inject any custom message with any GID and Callsign using a software defined radio in existing goTenna mesh networks. This vulnerability can be exploited if the device is being used in …

Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in goTenna Pro
The goTenna Pro App does not use SecureRandom when generating passwords for sharing cryptographic keys. The random function in use makes it easier for attackers to brute force this password if the broadcasted encryption key is captured over RF. This only appl…

Cleartext Transmission of Sensitive Information in goTenna Pro
The goTenna Pro App does not encrypt callsigns in messages. It is recommended to not use sensitive information in callsigns when using this and previous versions of the app and update your app to the current app version which uses AES-256 encryption for calls…

Missing Support for Integrity Check in goTenna Pro
The goTenna Pro App uses AES CTR type encryption for short, encrypted messages without any additional integrity checking mechanisms. This leaves messages malleable to an attacker that can access the message. It is recommended to continue to use encryption in …

Insecure Storage of Sensitive Information in goTenna Pro
In the goTenna Pro App, the encryption keys are stored along with a static IV on the End User Device (EUD). This allows for complete decryption of keys stored on the EUD if physically compromised. This allows an attacker to decrypt all encrypted broadcast com…

Weak Passwords Requirements in goTenna Pro
The goTenna Pro App uses a weak password for sharing encryption keys via the key broadcast method. If the broadcasted encryption key is captured over RF, and password is cracked via brute force attack, it is possible to decrypt it and use it to decrypt all fu…
