Impact
If a malicious actor is able to trigger Trivy to scan container images from a crafted malicious registry, it could result in the leakage of credentials for legitimate registries such as AWS Elastic Container Registry (ECR), Google Cloud Artifact/Container Registry, or Azure Container Registry (ACR). These tokens can then be used to push/pull images from those registries to which the identity/user running Trivy has access.
Taking AWS as an example, the leakage only occurs when Trivy is able to transparently obtain registry credentials from the default credential provider chain. You are affected if Trivy is executed in any of the following situations:
- The environment variables contain static AWS credentials (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN) that have access to ECR.
- Within a Pod running on an EKS cluster that has been assigned a role with access to ECR using an IAM Roles for Service Accounts (IRSA) annotation.
- etc.
You are not affected if the default credential provider chain is unable to obtain valid credentials. The same applies to GCP and Azure.
Workarounds
If you are using Trivy v0.51.2 or later, you are not affected. If you are using Trivy v0.51.1 or prior, you should ensure you only scan images from trusted registries.
This vulnerability only applies when scanning container images directly from a registry. If you use Docker, containerd or other runtime to pull images locally and scan them with Trivy, you are not affected. To enforce this behavior, you can use the --image-src flag to select which sources you trust.
The vulnerability requires local access to the device to be exploited. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker does not need any special privileges or access rights. The attacker needs the user to perform some action, like clicking a link. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
