CVE-2022-39030
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 · uneditedsmart eVision has inadequate authorization for system information query function. An unauthenticated remote attacker, 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 confidencesmart eVision contains a system information query function that lacks proper authorization controls. An unauthenticated remote attacker can directly access this function to retrieve sensitive system information without any credentials or authentication.

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 the installed version of Lcnet Smart EvisionCheck the product version displayed in the application UI, startup logs, or installation metadata. Common locations include the About section, version info in the web interface, or the installed software inventory.Affected if The installed version is 2022.02.21 exactly, matching the affected version listed in the CVE.
-
Locate the system information query function endpointIdentify if the application exposes a system information or diagnostics endpoint. This may be a web API endpoint, a specific URL path, or a function module. Check the application documentation or enumerate common paths like /system/info, /diagnostics, /api/system, or similar.Affected if The system information query function exists and is accessible via a network-exposed endpoint.
-
Verify if the function is accessible without authenticationAttempt to access the identified system information endpoint directly using a web browser, curl, or similar tool without providing any login credentials, session cookies, or authentication tokens.Affected if The endpoint returns system information without requiring any credentials or authentication, confirming the authorization bypass.
-
Confirm the nature of exposed informationReview the response from the unauthenticated access attempt to determine if sensitive system information is disclosed, such as server details, configuration, internal paths, or other potentially sensitive data.Affected if The response contains sensitive system information that should not be accessible to unauthenticated users.
You are affected if you are running Lcnet Smart Evision version 2022.02.21 AND the system information query function is network-accessible AND responds to unauthenticated requests with sensitive data.

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 robust authorization checks requiring valid authentication before granting access to the system information query function. Ensure all sensitive endpoints enforce proper session validation and role-based access controls.
