CVE-2019-7281
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 · uneditedPrima Systems FlexAir, Versions 2.3.38 and prior. An unauthenticated user can send unverified HTTP requests, which may allow the attacker to perform certain actions with administrative privileges if a logged-in user visits a malicious website.
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 confidenceCSRF vulnerability in Prima Systems FlexAir allows unauthenticated attackers to send forged HTTP requests via a malicious website visited by a logged-in administrator. Since the application does not validate anti-CSRF tokens or verify request origins, attackers can perform administrative actions with the victim's privileges.

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 FlexAir versionLocate the installed version of Prima Systems FlexAir by checking the application interface, version file, or HTTP response headers. Common locations include the login page, about page, admin panel, or server response headers.Affected if The installed version is 2.3.38 or lower
-
Inspect HTML forms for anti-CSRF tokensView the page source of key forms (login, admin actions, user management) and search for hidden input fields containing anti-CSRF tokens. Look for field names like 'csrf_token', 'token', 'nonce', or similar.Affected if No anti-CSRF token fields are present in state-changing HTML forms
-
Test Origin header validationSend a state-changing request (such as a configuration change or user creation) with a mismatched or missing Origin header. Check if the application accepts or rejects the request based on the Origin header.Affected if The application accepts requests with arbitrary or missing Origin headers without validation
-
Verify SameSite cookie configurationLog into FlexAir and capture the session cookie from the HTTP response. Inspect the Set-Cookie header to determine if the SameSite attribute is set (Strict, Lax, or None).Affected if The session cookie lacks a SameSite attribute or uses SameSite=None without Secure flag
The environment is affected if FlexAir version is 2.3.38 or lower and none of the anti-CSRF protections (token validation, Origin/Referer header checks, or SameSite cookie attributes) are implemented.
Generated from the published advisory. Verify against your own configuration.
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 dataImplement synchronizer token pattern for all state-changing operations, validate Origin/Referer headers on requests, and configure SameSite cookie attributes to prevent cross-site request forgery.
