CVE-2021-32076
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 · uneditedAccess Restriction Bypass via referrer spoof was discovered in SolarWinds Web Help Desk 12.7.2. An attacker can access the 'Web Help Desk Getting Started Wizard', especially the admin account creation page, from a non-privileged IP address network range or loopback address by intercepting the HTTP request and changing the referrer from the public IP address to the loopback.
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 confidenceSolarWinds Web Help Desk 12.7.2 has an access restriction bypass vulnerability where the application relies on the HTTP Referer header to control access to the Getting Started Wizard and admin account creation page. An attacker can intercept requests and modify the Referer header from the public IP to a loopback address (127.0.0.1), bypassing IP-based access controls that were intended to restrict these sensitive pages to internal networks only.

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 SolarWinds Web Help Desk versionCheck the installed version by reviewing the software documentation, installation directory, or running: locate the version info in the application or check the SolarWinds licensing/about pageAffected if Installed version is 12.7.2 or lower
-
Locate the Getting Started Wizard endpointIdentify the application URL path for the Getting Started Wizard - typically accessible via HTTP/HTTPS to the Web Help Desk serverAffected if The Getting Started Wizard endpoint is reachable without authentication
-
Test admin account creation page accessibilityAttempt to access the admin account creation page without providing any credentials or session tokenAffected if The admin account creation page is accessible without being logged in
-
Verify Referer header-based access controlSend a crafted HTTP request to the protected pages with the Referer header set to http://127.0.0.1 or similar loopback address while the request originates from an external IPAffected if Modifying the Referer header from an external IP allows access to pages that should be restricted to internal networks only
A user is affected if SolarWinds Web Help Desk version 12.7.2 or lower is installed AND the Getting Started Wizard or admin account creation pages can be accessed without proper authentication by manipulating the HTTP Referer header.

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 dataReplace referrer-based access control with proper server-side authentication and authorization checks. Validate client IP addresses server-side and ensure admin account creation pages require authenticated sessions with proper role-based access controls.
