CVE-2023-40535
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 · uneditedStored cross-site scripting vulnerability in View setting page of VI Web Client prior to 7.9.6 allows a remote authenticated attacker to inject an arbitrary script.
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 confidenceA stored cross-site scripting vulnerability exists in the View settings page of VI Web Client versions prior to 7.9.6. An authenticated attacker can inject malicious JavaScript code that gets stored in the application and executes in the browsers of other users who access the View settings page.

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 VI Web Client versionLocate the version information for I Pro Video Insight (VI Web Client) in the application's about page, admin panel, or installation directory. Common locations include the web interface footer, a version info file, or the software's system information page.Affected if Version is below 7.9.6
-
Verify View settings page accessibilityNavigate to the View settings page in the VI Web Client interface. This is typically found in the administration or configuration section of the web client.Affected if The View settings page loads and is accessible to authenticated users
-
Confirm authentication requirements for the affected pageCheck the access control configuration for the VI Web Client and specifically the View settings page to determine what level of authentication is required.Affected if Authenticated users can access the View settings page (the vulnerability requires an authenticated attacker to inject the payload)
Your environment is affected if VI Web Client (I Pro Video Insight) is installed at a version lower than 7.9.6 and the View settings page is accessible to authenticated users.
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 · scoped7.9.6
Upgrade VI Web Client to version 7.9.6 or later. Until upgraded, restrict access to authenticated users only and implement output encoding on user-supplied data displayed in the View settings page.
Video Insight 7.9.6 or later
- Identify the current Video Insight VI Web Client version currently deployed
- Back up all Video Insight configurations, databases, and important data before proceeding with the upgrade
- Download Video Insight version 7.9.6 or later from the official vendor download source (downloadvi.com or authorized channel)
- Install or apply the upgrade following the vendor's documented upgrade procedure
- Verify the installed version shows 7.9.6 or later after completing the upgrade
- Test the View setting page in the VI Web Client to confirm the application functions correctly and the XSS vulnerability is remediated
