API on port 8800. This CVE was originally reserved in 2021 and later publicly disclosed by Replicated on their website on 21 October 2021. However, it mistakenly remained in the Reserved But Public (RBP) status with the CVE Numbering Authority (CNA). Please note that this product reached its end of life on 31 December 2024. Publishing this CVE with the CNA was required to comply with CNA rules, despite the fact that the issue was disclosed and fixed four years ago, and the affected product is no longer supported as of 2024. Summary of VulnerabilityThis advisory discloses a low severity security vulnerability in the versions of Replicated Classic listed above (“Affected Replicated Classic Versions”) DescriptionReplicated Classic versions prior to 2.53.1 have an authenticated API from the Replicated Admin Console that may expose sensitive data including application secrets, depending on how the application manifests are written. A user with valid credentials and access to the Admin Console port (8800) on the Replicated Classic server can retrieve container definitions including environment variables which may contain passwords and other secrets depending on how the application is configured. This data is shared over authenticated sessions to the Admin Console only, and was never displayed or used in the application processing. To remediate this issue, we removed the sensitive data from the API, sending only the data to the Admin Console that was needed. TimelineThis issue was discovered during a security review on 16 September 2021. Patched versions were released on 23 September 2021. This advisory was published on 21 October 2021. The CVE Numbering Authority (CNA) notified Replicated on 23 January 2025 that the CVE was still in Reserved But Public (RBP) status. Upon discovering the oversight in updating the status to published with the CNA, Replicated submitted the updated report on the same day, 23 January 2025.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Tracking information locations and access supports secure storage practices instead of insecure ones.
Establishing an alternate site with equivalent protections directly mitigates insecure storage of sensitive backup information.
Requiring protection of backup information directly addresses insecure storage of sensitive data in backups.
Policy explicitly addresses insecure storage of CUI on external systems, requiring compliant handling and protections.
Proper categorization drives selection of storage controls that keep sensitive information from being stored insecurely.
The control explicitly requires secure storage mechanisms for sensitive information, closing the insecure-storage weakness class.
Storing information as fragments on distinct components is an architectural control that avoids insecure single-location storage of the complete sensitive data set.
OPSEC requirements improve handling and storage practices for sensitive supply-chain information.
