CVE-2019-1958
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 · uneditedA vulnerability in the web-based management interface of Cisco HyperFlex Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user.
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 confidenceThis is a Cross-Site Request Forgery (CSRF) vulnerability in Cisco HyperFlex Software's web-based management interface. The vulnerability exists because the web UI lacks proper CSRF protection mechanisms, allowing an unauthenticated remote attacker to craft malicious links that, when clicked by an authenticated user, can cause the user's browser to perform unauthorized actions with that user's privilege level.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify if Cisco HyperFlex Hx Data Platform is installedLocate the HyperFlex installation by checking for Hx Data Platform components, or access the management interface URL and look for HyperFlex branding and login pageAffected if The system runs Cisco HyperFlex Hx Data Platform software
-
Check the installed version of HyperFlex Hx Data PlatformAccess the web management interface, navigate to the About or System Information page, or run 'hxsh' commands to retrieve the version numberAffected if The installed version is earlier than 4.0(2a)
-
Confirm the web-based management interface is accessibleAttempt to access the HyperFlex web UI via HTTPS on the management IP addressAffected if The web management interface is reachable and accepts authentication
-
Verify the CSRF protection mechanism is absentSubmit a state-changing request (such as creating a user or modifying settings) without the proper CSRF token headers and observe if the request is acceptedAffected if The web interface accepts state-changing operations without validating CSRF tokens or Origin/Referer headers
The environment is affected if Cisco HyperFlex Hx Data Platform version 4.0(2a) or later is not installed, and the web management interface processes requests without CSRF token validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data4.0
Enable and implement CSRF protections in the web-based management interface, including anti-CSRF tokens for state-changing operations and validation of Origin/Referer headers. Users should be advised to avoid clicking untrusted links while authenticated to the management interface.
