This threat actor exploited an SSRF flaw in Adminer (CVE-2021-21311) to steal credentials from IMDS, demonstrating that this attack vector has been weaponized by advanced persistent threat groups for years.

The application must send a PUT request containing a specific header ( X-aws-ec2-metadata-token-ttl-seconds ) to generate a secret token.

If an attacker can cause a vulnerable application (e.g., a PHP, Node.js, or Java app that follows external URLs) to make a request to this decoded endpoint, the server will return the active IAM role's . This threat actor exploited an SSRF flaw in

In the ecosystem of Amazon Web Services (AWS), automation and security are paramount. One of the most critical mechanisms that binds these two concepts together is the Instance Metadata Service (IMDS). The URL http://169.254.169.254/latest/meta-data/iam/security-credentials/ is the specific pathway through which applications running on an EC2 instance retrieve the temporary security credentials required to interact with other AWS services.

is a used by cloud providers to expose instance metadata. It is only reachable from within the EC2 instance itself. This means that if an attacker can make a server-side application (like a web server) request a URL of their choosing, they can potentially access this metadata. The Role of /latest/meta-data/iam/security-credentials/ In the ecosystem of Amazon Web Services (AWS),

This is a public internet address. It is an internal, non-routable IP address reserved for instance metadata services, specifically within Amazon Web Services (AWS) , though other clouds (Google Cloud, Azure, OpenStack) use similar endpoints.

In modern cloud computing, particularly within Amazon Web Services (AWS) , the ability for an instance to know about itself is crucial. This information is provided through the , which is accessed via the specific IP address . is a used by cloud providers to expose instance metadata

Ensure that the IAM roles attached to your cloud instances hold only the minimum permissions necessary to perform their tasks. Even if an attacker successfully exploits an SSRF vulnerability to dump the security credentials, their lateral movement and data exfiltration capabilities will be severely limited by the constrained permissions of the compromised role.
