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.

This is a reflected XSS issue where user-supplied input in the URL is not properly sanitized before being rendered in the web interface.

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.
-
Check installed Lansweeper versionOpen the Lansweeper web console and look for the version number typically displayed in the footer of the main page, or access the 'Configuration' > 'Server Options' page in the web interface where the build version is listedAffected if The displayed version is exactly 7.2.105.2
-
Verify web console is accessibleConfirm you can access the Lansweeper web console by navigating to the server's URL (typically http://servername or http://servername:81)Affected if The web console is accessible and responds to HTTP requests
-
Confirm URL path reflection in web interfaceAccess the Lansweeper web console using a test URL with a script payload in the path (for example, navigate to http://yourserver/<script>alert(1)</script>) and observe if the payload is reflected in the page response without encodingAffected if The URL path is rendered in the page without sanitization and the script executes or is visible in the page source

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 dataUpgrade Lansweeper to the patched version released on or after December 2, 2019 as documented in the product changelog. Input validation and output encoding should also be implemented on the web console as a defense-in-depth measure.
