    1. An attacker who successfully exploited the vulnerability could elevate privileges and read any file on the file system with SYSTEM access permissions;

    2. An attacker who successfully exploits this vulnerability can only obtain read access to the system files by exploiting this vulnerability. The attacker cannot perform write or delete operations on the files;

    3. The vulnerability exists in the following credential types: DefaultAzureCredential and ManagedIdentityCredential;

    4. The vulnerability exists in the following credential types:

    ManagedIdentityApplication (.NET)
