CVE-2024-37293: The AWS Deployment Framework (ADF) is a framework to manage and deploy resources across multiple AWS accounts and regions within an AWS Organization. ADF allows for staged, parallel, multi-account, cross-region deployments of applications or resources via the structure defined in AWS Organizations while taking advantage of services such as AWS CodePipeline, AWS CodeBuild, and AWS CodeCommit to alleviate the heavy lifting and management compared to a traditional CI/CD setup. ADF contains a bootstrap process that is responsible to deploy ADF's bootstrap stacks to facilitate multi-account cross-region deployments. The ADF bootstrap process relies on elevated privileges to perform this task. Two versions of the bootstrap process exist; a code-change driven pipeline using AWS CodeBuild and an event-driven state machine using AWS Lambda. If an actor has permissions to change the behavior of the CodeBuild project or the Lambda function, they would be able to escalate their privileges. Prior to version 4.0.0, the bootstrap CodeBuild role provides access to the `sts:AssumeRole` operation without further restrictions. Therefore, it is able to assume into any AWS Account in the AWS Organization with the elevated privileges provided by the cross-account access role. By default, this role is not restricted when it is created by AWS Organizations, providing Administrator level access to the AWS resources in the AWS Account. The patches for this issue are included in `aws-deployment-framework` version 4.0.0. As a temporary mitigation, add a permissions boundary to the roles created by ADF in the management account. The permissions boundary should deny all IAM and STS actions. This permissions boundary should be in place until you upgrade ADF or bootstrap a new account. While the permissions boundary is in place, the account management and bootstrapping of accounts are unable to create, update, or assume into roles. This mitigates the privilege escalation risk, but also disables ADF's ability to create, manage, and bootstrap accounts.
The exploitability of CVE-2024-37293 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
The exploitability of CVE-2024-37293 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2024-37293, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2024-37293, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.042% (probability of exploit)
EPSS Percentile: 5.02%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 94.98% of others.
