CompTIA PenTest+ (PT0-003)Attacks and ExploitsEasy
A red team is conducting an assessment of an organization's cloud environment. They discover an S3 bucket configured for public read access. The bucket contains several Python scripts that appear to be used for data processing, along with configuration files containing API keys and database credentials. Which of the following attack types BEST describes this scenario?
- AServer-Side Request Forgery (SSRF)
- BPublic Cloud Storage Misconfiguration
- CIAM PassRole Privilege Escalation
- DCloud Metadata Service Exploitation
Show answer & explanationAnswer & explanation
Correct answer: B. Public Cloud Storage Misconfiguration
The scenario describes an S3 bucket with public read access, leading to the exposure of sensitive data like API keys and credentials. This is a classic example of a public cloud storage misconfiguration, where inadequate access controls are applied to storage resources, making them publicly accessible.
Why the other options are wrong
- A. SSRF involves the server making requests on behalf of the attacker, not direct access to a misconfigured bucket.
- C. IAM PassRole privilege escalation is about gaining higher privileges through IAM roles, not misconfigured storage.
- D. Cloud Metadata Service Exploitation involves accessing instance metadata, not directly misconfigured storage buckets.
Public Cloud Storage Misconfiguration
A security vulnerability where cloud storage resources (e.g., S3 buckets, Azure Blobs) are inadvertently configured with public read/write access, exposing sensitive data to unauthorized individuals.
- Commonly results from incorrect bucket policies or ACLs.
- Can lead to data leakage, data tampering, or full compromise.
- Often discovered via automated scanning tools or OSINT.
Memory trick: Open buckets spill secrets for all to see.
