CVE-2024-47121

Message decryption via brute-forced broadcast key password

Published Sep 26, 2024 · Updated May 2, 2025

Weak password requirements in goTenna Pro 1.61 and earlier allow physically proximate attackers to decrypt broadcasts after RF key capture. The key-broadcast method protects a shared encryption key with a weak password, enabling offline brute-force recovery from a captured radio transmission. Exploitation requires the optional RF key-broadcast feature; recovery exposes past and future encrypted broadcasts using that key.
