Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in the web-based UI of Cisco HyperFlex HX Data Platform Software could allow an unauthenticated, remote attacker to access sensitive information on an affected system. The vulnerability is due to a lack of proper input and authorization of HTTP requests. An attacker could exploit this vulnerability by sending a malicious HTTP request to the web-based UI of an affected system. A successful exploit could allow the attacker to access files that may contain sensitive data.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A path traversal or improper authorization vulnerability in the Cisco HyperFlex HX Data Platform web-based UI allows unauthenticated remote attackers to access sensitive files on the underlying filesystem by sending crafted HTTP requests. The lack of input validation and authorization checks on HTTP parameters enables directory traversal or arbitrary file disclosure.

MitigationApply the vendor patch from Cisco for this vulnerability. If no patch is available, consider restricting web UI access to trusted networks via firewall rules or disabling the web UI if not required, while monitoring for suspicious HTTP activity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed HyperFlex HX Data Platform version
    Access the HyperFlex cluster management interface or use the 'show version' command via SSH to the HX cluster. Alternatively, check the installed software version through the vCenter plugin or the HyperFlex Connect UI.
    Affected if The installed version is exactly 2.6(1d) or exactly 3.0(1a)
  2. Confirm the web-based UI is enabled
    Verify whether the HyperFlex web-based management UI is accessible and enabled. This is typically accessed on port 443 or 8443 for the HX Data Platform web interface.
    Affected if The web-based UI is exposed and accessible to network users
  3. Check network exposure of the management interface
    Review firewall rules, security groups, or ACLs to determine if the HyperFlex management web interface is reachable from untrusted networks or the internet.
    Affected if The web UI is accessible from untrusted or external networks without proper filtering
  4. Review HTTP access logs for suspicious requests
    Examine the HyperFlex web server logs for patterns indicative of path traversal attempts, such as requests containing '../' sequences or unusual file access patterns targeting system files.
    Affected if Logs show unauthorized traversal attempts or anomalous file access requests to the web interface

A system is affected if it runs HyperFlex HX Data Platform versions 2.6(1d) or 3.0(1a) with the web-based UI enabled and accessible, particularly from untrusted networks.
