Executive Summary

This vulnerability is a cryptographic issue that occurs when a static initialization vector (IV) is used for AES-GCM key wrapping. AES-GCM requires a unique IV for each encryption operation to maintain security. Using a static IV compromises the security guarantees of AES-GCM.

Impact Analysis

The impact of this vulnerability is that it can lead to a compromise of confidentiality and integrity of the encrypted data. Since the IV is static, attackers may be able to decrypt or manipulate the wrapped keys, leading to potential unauthorized access or data breaches.
