Technical details
The device implements AES encryption in Cipher Block Chaining (CBC) mode using a static, zero-filled Initialization Vector (IV). In CBC mode, the IV should be unique and unpredictable for every encryption operation to ensure that identical plaintexts result in different ciphertexts. By using a fixed IV, the implementation becomes vulnerable to replay attacks and known-plaintext attacks, allowing an attacker to potentially decrypt traffic or manipulate data streams. The vulnerability is identified as CVE-2026-50210 and affects firmware versions up to M6E_AI_1.00.000019.
