CVE-2020-3973
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 · uneditedThe VeloCloud Orchestrator does not apply correct input validation which allows for blind SQL-injection. A malicious actor with tenant access to Velocloud Orchestrator could enter specially crafted SQL queries and obtain data to which they are not privileged.
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 · moderate confidenceVeloCloud Orchestrator fails to properly validate user input in tenant-accessible fields, enabling an authenticated attacker to inject malicious SQL queries. As a blind SQL injection, the attacker cannot directly see query results but can infer information through behavioral differences (timing, true/false conditions) to exfiltrate unauthorized data from the database.

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.
-
Determine VeloCloud Orchestrator versionAccess the VeloCloud Orchestrator admin interface and navigate to the About or System Information page to view the installed version number, or use the API endpoint /api/version if accessibleAffected if The installed version falls within >= 3.1.1 and < 3.3.2, or is exactly 3.3.2, or is exactly 3.4.0
-
Verify tenant authentication is enabledConfirm that multi-tenancy is enabled in the Orchestrator settings and that tenant users can authenticate to the systemAffected if Tenant-level user authentication is active, which enables the attack vector
-
Identify tenant-accessible input fieldsLog in with a tenant-level account and inspect forms, search fields, or API parameters in tenant-accessible endpoints such as portal pages or API routes under /api/tenant/Affected if Unsantized input fields exist in tenant-accessible endpoints that accept user-supplied data
-
Check for SQL injection vulnerability indicatorsSubmit SQL-safe characters like single quotes (') in tenant-accessible input fields and observe for database error messages, unusual response delays (blind SQLi), or altered application behaviorAffected if Input validation is absent and SQL syntax triggers error messages or timing differences in responses
The environment is affected if VeloCloud Orchestrator version is 3.1.1 through 3.3.1, exactly 3.3.2, or exactly 3.4.0 AND tenant users can access input fields that lack proper input validation and allow SQL injection.

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 data3.3.2
Implement strict input validation and use parameterized queries or prepared statements for all database interactions. Apply the vendor patch when available and audit existing queries for similar injection flaws.
