Introduction

AWS Identity and Access Management (IAM) is at the heart of cloud security. A single misconfigured permission can lead to full account takeover.

In bug bounty programs, IAM privilege escalation is one of the most rewarding tricks, as hunters can pivot from low-privilege roles → admin access without “hacking” the infrastructure.

 What is IAM Privilege Escalation?

It’s when a user with limited IAM permissions leverages misconfigured policies to gain higher privileges.

Example:

• Role DevUser has access to iam:PassRole but not to ec2:RunInstances.

• If misconfigured, the user can pass an admin role to an EC2 instance → escalate.

 Common Privilege Escalation Paths

 PassRole + Create EC2

• Permission: iam:PassRole + ec2:RunInstances

• Trick: Launch EC2 with Admin Role attached → SSH → full privilege.

 PassRole + Lambda

• Permission: iam:PassRole + lambda:CreateFunction

• Trick: Deploy Lambda with admin role, execute arbitrary code.

 Policy Attachment Abuse

• Permission: iam:AttachUserPolicy or iam:PutUserPolicy

• Trick: Attach AdministratorAccess to your own user.

 Update Login Profile

• Permission: iam:UpdateLoginProfile

• Trick: Change the password of another IAM user (often admin).

 Access Key Creation

• Permission: iam:CreateAccessKey

• Trick: Generate new access keys for another IAM user → API access.

 Bug Bounty Exploitation Workflow

Step 1: Recon

• Enumerate IAM permissions using:

  aws iam list-attached-user-policies
  aws iam list-user-policies
  aws iam list-roles
  

Step 2: Identify Escalation Vectors

• Look for suspicious combinations (PassRole + CreateFunction, AttachUserPolicy, UpdateLoginProfile).

Step 3: Exploit Misconfig

• Deploy Lambda with escalated role.

• Or attach AdministratorAccess to self.

Step 4: Pivot

• Use elevated creds to access S3, DynamoDB, RDS, Secrets Manager.

Step 5: Report & Document

• Write a clear PoC with exploited policies.

• Provide AWS CLI commands as proof.

• Identity governance in cloud

 CyberDudeBivash Recommendations

• For Bug Bounty Hunters: Always check IAM roles & attached policies. Most reports are low-hanging fruit.

• For Cloud Security Engineers: Implement least privilege IAM + IAM Access Analyzer.

• For Enterprises: Run cloud penetration tests quarterly.

• For Developers: Never give broad iam:* permissions.

 Conclusion

IAM privilege escalation is the silent killer in AWS bug bounties. With just a few misconfigured policies, attackers can jump from restricted user → full admin control.

For bug bounty hunters, this is a gold mine. For enterprises, it’s a compliance nightmare.
