CVE-2024-47126: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in goTenna Pro
- Severity: high (CVSS 8.8 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.2% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2024-09-26 · updated 2026-06-17
- Weakness: CWE-338
Description
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 applies to the optional broadcast of an encryption key, so it is advised to share the key with local QR code for higher security operations.
Affected products
- goTenna Pro: through 1.6.1; before 2.0.3 — fixed in 2.0.3
How to fix
Upgrade to a fixed version: goTenna Pro 2.0.3. Check the vendor advisory for mitigations.
