Risk

High

An unrestricted escalation path, identity administration, secret reads or the power to switch off security monitoring. Read from this policy document alone: trust policies, boundaries and SCPs in your account still decide what actually succeeds. How this is assessed

  • High

    Can take over existing resources that run as another role

    Grants every action of 1 documented escalation path on any resource with no condition.

    Use with caution: List the roles attached to the functions, instances, pipelines or notebooks it can modify: the holder effectively has them too.

  • Medium

    Can launch resources that run as a more privileged role

    Grants the actions of 1 documented escalation path, but only on named resources or under a condition. Review that scope before trusting it.

    • ec2-001iam:PassRole + ec2:RunInstancesscoped
      • iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/AWSRDSCustom*

    Use with caution: Check which roles, users or policies fall inside the scope shown above. Within it the escalation works as documented, so keep privileged principals out of it.

  • Warning / POLICY_SIZE_EXCEEDS_IDENTITY_POLICY_QUOTA

    The 11599 characters in the identity policy, excluding whitespace, exceed the 10240 character maximum for inline and managed policies. We recommend that you use multiple granular policies. AWS docs
