CVE-2024-52314 is a vulnerability classified under CWE-863 (Incorrect Authorization) affecting Amazon's data.all product, specifically version 1.0.0. The flaw arises because a data.all admin team member who has access to the customer-owned AWS account where data.all is deployed can extract user data by scanning CloudWatch logs. These logs contain records of operations that interact with customer producer teams' data, which may include sensitive or confidential information. The vulnerability exploits insufficient authorization checks on log data access, allowing privileged users to bypass intended data access restrictions. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no authentication required (AT:N), but requires high privileges (PR:H) within the AWS account. There is no user interaction (UI:N), and the impact is high on confidentiality (VC:H) but none on integrity or availability. The vulnerability does not require scope or security impact changes beyond the affected component. No patches or known exploits are currently available, and the vulnerability was published on November 9, 2024. This issue highlights the risk of sensitive data leakage through operational logs in cloud environments when authorization controls are insufficiently enforced on privileged roles.

For European organizations, the impact of CVE-2024-52314 centers on potential unauthorized disclosure of sensitive user data through CloudWatch logs accessible by data.all admin team members with high privileges. This could lead to breaches of confidentiality, regulatory non-compliance (e.g., GDPR), and reputational damage. Organizations with multi-team AWS deployments using data.all are particularly at risk, as logs may contain cross-team data interactions. The vulnerability does not affect system integrity or availability but compromises trust in data handling and access controls. Given the reliance on AWS in Europe and the sensitivity of customer data processed in cloud environments, this vulnerability could expose critical business or personal data if exploited. The medium severity reflects the requirement for high privilege access, limiting the attack surface to insiders or compromised admin accounts. Nevertheless, insider threats or privilege escalation scenarios could leverage this vulnerability to extract data undetected.

To mitigate CVE-2024-52314, European organizations should implement strict access controls and monitoring for AWS accounts hosting data.all deployments. Specifically: 1) Limit data.all admin team member privileges to the minimum necessary, enforcing least privilege principles. 2) Audit and restrict CloudWatch log access permissions to prevent unauthorized scanning or extraction of sensitive data. 3) Implement logging and alerting on unusual log access patterns or data extraction attempts within CloudWatch. 4) Use AWS IAM policies to segregate duties and restrict cross-team data visibility in logs. 5) Regularly review and rotate credentials for admin roles to reduce risk of compromise. 6) Consider encrypting sensitive log data or using log redaction techniques to minimize exposure. 7) Monitor AWS account activity for signs of insider threat or privilege misuse. 8) Engage with Amazon support or security advisories for updates or patches addressing this vulnerability. These measures go beyond generic advice by focusing on operational controls around privileged access and log data governance specific to data.all and AWS CloudWatch.
