CVE-2021-37214
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 employee management page of Flygo contains Insecure Direct Object Reference (IDOR) vulnerability. After being authenticated as a general user, remote attackers can manipulate the employee ID in specific parameters to arbitrary access employee's data, modify it, and then obtain administrator privilege and execute arbitrary command.
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 confidenceFlygo's employee management page contains an IDOR vulnerability where the employee ID parameter lacks proper authorization validation. An authenticated general user can manipulate this parameter to access and modify arbitrary employee records, escalate to administrator privileges, and achieve arbitrary command execution.

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 installed Larvata Flygo versionLocate the version file or check the application metadata (typically in config/version.php, package.json, or the application's about/footer section). Compare the version number to 1.91.1.Affected if The installed version is below 1.91.1
-
Confirm employee management module is activeAccess the employee management page within the application using an authenticated general (non-admin) user account. Verify the module is accessible in the navigation menu or direct URL.Affected if The employee management module is present and accessible to general users
-
Check user role configurationReview the application's user role settings or database table that defines user roles (often found in users table with role_id or role field). Determine if general users have any employee record access permissions.Affected if General users have permissions to view or access employee records through the application
-
Inspect API or endpoint authorization logsExamine application logs for access attempts to employee endpoints (such as /employee/show/{id} or /employee/edit/{id}) using non-admin credentials. Look for 200 OK responses on records belonging to other users.Affected if General users successfully access employee records belonging to other users without admin privileges
If the installed version is below 1.91.1 and general authenticated users can access the employee management module, the environment is likely affected by this IDOR vulnerability.
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.
dbcve · scoped1.91.1
Implement strict object-level authorization checks on all employee management endpoints to verify the requesting user has explicit permission to access or modify the requested employee data. Additionally, enforce role-based access controls (RBAC) to prevent privilege escalation and audit all similar endpoints for IDOR vulnerabilities.
Flygo version 1.91.1
- Download Flygo version 1.91.1 or later from the official vendor repository
- Backup the current Flygo installation and database before upgrading
- Install the upgraded version (1.91.1 or later) following the vendor's standard upgrade procedure
- Verify that the employee management page no longer allows IDOR exploitation by testing with a non-admin user account
- Confirm that user privilege escalation is properly enforced and employee IDs cannot be manipulated via URL parameters
