Risk

Medium

The same capabilities in a scoped form, resource policy writes, reads across all data, or full access to a whole service. Read from this policy document alone: trust policies, boundaries and SCPs in your account still decide what actually succeeds. How this is assessed

  • Medium

    Can grant itself more permissions

    Grants the actions of 2 documented escalation paths, but only on named resources or under a condition. Review that scope before trusting it.

    • iam-005iam:PutRolePolicyscoped
      • iam:PutRolePolicy: condition aws:ResourceAccount, aws:ResourceTag/CreatedBy, iam:PermissionsBoundary, on arn:aws:iam::*:role/SDMP-*
    • iam-009iam:AttachRolePolicyscoped
      • iam:AttachRolePolicy: condition aws:ResourceAccount, aws:ResourceTag/CreatedBy, iam:PermissionsBoundary, on arn:aws:iam::*:role/SDMP-*

    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.
