CVE-2024-56141Network attack vector

Secret-key recovery via key-derived AES IV

Published Jul 6, 2026 · Updated Jul 6, 2026

Predictable AES IV generation in Bixilon Minosoft for protocol 1.7 and later allows remote authenticated users to recover the secret key. The CryptManager.kt encryption routine passes key.encoded to IvParameterSpec, making the AES initialization vector identical to the secret key instead of unpredictable. Exploitation requires the ability to submit chosen messages for encryption; successful attacks disclose the secret key and compromise traffic protected by it.
