What is CVE-2024-47121?
CVE-2024-47121 is a medium-severity vulnerability in goTenna Pro, published on 26 Sep 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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 future and past messages sent via encrypted broadcast with that particular key. This only applies when the key is broadcasted over RF. This is an optional feature, so it is recommended to use local QR encryption key sharing for additional security on this and previous versions.
