Security readout for executives and security teams
Plain-English summary
Apache Ambari 2.6.2.2 and earlier can allow a malicious user to craft filenames that move outside the intended directory and download other files. For executives, the concern is unintended file disclosure from a cluster management system. The sources do not provide CVSS, exploit details, or confirmed active exploitation.
Executive priority
Treat this as a timely exposure review for legacy Ambari environments. It is not KEV-listed in the provided data, but file disclosure from a management platform can carry material operational risk.
Technical view
CVE-2020-13924 is a directory traversal issue in Apache Ambari 2.6.2.2 and earlier. The published description says constructed filenames can traverse directories and download files. The provided sources do not identify the specific endpoint, authentication requirements, impacted file scope, or fixed version.
Likely exposure
Organizations running Apache Ambari 2.6.2.2 or earlier are potentially exposed, especially where Ambari is reachable by untrusted users or broad internal audiences.
Exploitation context
The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. It only states that malicious users can craft filenames for directory traversal and file download.
Researcher notes
Evidence is sparse. The record supports directory traversal and file download impact in Ambari 2.6.2.2 and earlier, but not exploit maturity, affected endpoint, prerequisites, or patch details. Avoid assuming unauthenticated access without vendor confirmation.
Mitigation direction
- Inventory Apache Ambari deployments and record exact versions.
- Prioritize replacing or upgrading Ambari 2.6.2.2 and earlier per Apache guidance.
- Restrict Ambari access to trusted administrators and management networks.
- Review Ambari permissions for users who can trigger file download functionality.
- Monitor vendor advisories for the fixed version and operational workarounds.
Validation and detection
- Confirm whether any Ambari instance is version 2.6.2.2 or earlier.
- Check whether Ambari is reachable from untrusted networks or users.
- Review logs for unusual file download requests or traversal-like filename patterns.
- Verify that access controls limit Ambari use to authorized administrators.
- Document compensating controls if upgrade status cannot be confirmed.
