CVE-2020-13416
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 · uneditedAn issue was discovered in Aviatrix Controller before 5.4.1066. A Controller Web Interface session token parameter is not required on an API call, which opens the application up to a Cross Site Request Forgery (CSRF) vulnerability for password resets.
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 confidenceThe Aviatrix Controller before version 5.4.1066 lacks CSRF token validation on its API endpoints. Specifically, the password reset functionality does not require a session token parameter, allowing attackers to craft malicious requests that execute when an authenticated user visits a crafted page or link.

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 Aviatrix Controller in your environmentLocate the Aviatrix Controller by accessing its web interface or checking network inventory for systems running the Aviatrix Controller service on ports 443 or 80Affected if You have an Aviatrix Controller deployed and accessible
-
Determine installed Controller versionLog into the Aviatrix Controller web interface and navigate to the Settings > Maintenance > Upgrade page, or use the CLI command 'avx_version' if you have admin access, to identify the exact version numberAffected if The displayed version is less than 5.4.1066 (e.g., 5.4.x versions below 5.4.1066 or any version prior to 5.4)
-
Verify API CSRF protection statusInspect HTTP responses from the Controller's API endpoints (such as /v1/api) using a browser developer tool or curl. Send a request to the password reset endpoint without including a CSRF token header or cookie, and observe if the request is accepted without validation failureAffected if The API accepts requests without requiring a valid CSRF token, indicating the protection is missing
You are affected if your Aviatrix Controller version is below 5.4.1066 and lacks CSRF token validation on its API endpoints including password reset operations.
