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 · unedited
Smart eVision has inadequate authorization for the database query function. A remote attacker with general user privilege, who is not explicitly authorized to access the information, can access sensitive information.

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 confidence

Smart eVision contains an insecure direct object reference (IDOR) or broken access control vulnerability in its database query function. A remote attacker with basic general user credentials can bypass intended authorization restrictions and query sensitive database information they are not explicitly permitted to access.

MitigationImplement proper authorization checks on all database query functions to verify the requesting user has explicit permission to access the requested data. Enforce principle of least privilege and validate user permissions before executing any database queries.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Smart eVision version
    Locate the installed version of Lcnet Smart eVision (typically found in the product UI under 'About' or 'System Information', or in installation logs/configuration files)
    Affected if The installed version is 2022.02.21 or earlier
  2. Verify access to database query functionality
    Log in with a basic general user account and attempt to access the database query function/module within Smart eVision
    Affected if General users can access the database query feature at all (the vulnerability exists in the function itself)
  3. Test authorization boundaries
    Using a basic general user account, attempt to query database tables or data that should be restricted to higher-privileged roles (the vulnerability allows bypassing intended authorization)
    Affected if A basic user can access database information outside their authorized scope, indicating the IDOR/broken access control is present

A user is affected if they are running Smart eVision version 2022.02.21 or earlier AND the database query function is accessible to general users without proper authorization enforcement.

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 data
Upgrade available Upgrade to a release after 2022.02.21
Interim mitigation

Implement proper authorization checks on all database query functions to verify the requesting user has explicit permission to access the requested data. Enforce principle of least privilege and validate user permissions before executing any database queries.
