In our last aws penetration testing post we explored what a pentester could do after compromising credentials of a cloud server in this installment we ll look at an amazon web service aws instance from a no credential situation and specifically potential security vulnerabilities in aws s3 simple storage buckets.
Aws s3 security vulnerabilities.
Aws s3 buckets are exposing vast quantities of sensitive business data according to a new report from truffle security.
This vulnerability is prevalent in access to s3 buckets in aws.
Another reason is the lack of training.
Aws s3 common vulnerabilities.
Before we dig deep into the layers of s3 security in our on demand cloud security masterclass register here we thought we d take a quick look at three common ways aws customers put s3 data at risk without realizing it.
They are all placed in the security misconfiguration category in the detectify tool.
S3 bucket configured to allow anonymous users to list read or write data to the bucket.
This is the most common type of cloud security vulnerability.
Detectify scans for s3 misconfigurations with a severity range between 4 4 9 on the cvss scale.
The following security best practices also address configuration and vulnerability analysis in amazon s3.
To learn about the compliance programs that apply to amazon s3 see aws services in scope by compliance program.
The effectiveness of our security is regularly tested and verified by third party auditors as part of the aws compliance programs.
If you would like to report a vulnerability or have a security concern regarding aws.
It hurts because it is self inflicted.

With manual deep dive engagements we identify security vulnerabilities which put clients at risk.
Amazon s3 bucket allows for full anonymous access amazon s3 bucket allows for arbitrary file listing.
According to cloud security software experts the misconfigurations result from a lack of understanding of the cloud platform s shared model.
List permissions on compute resources.
