CVE-2020-29025
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 · uneditedA vulnerability in SiteManager-Embedded (SM-E) Web server which may allow attacker to construct a URL that if visited by another application user, will cause JavaScript code supplied by the attacker to execute within the user's browser in the context of that user's session with the application. This issue affects all versions and variants of SM-E prior to version 9.3
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 confidenceThis is a reflected Cross-Site Scripting (XSS) vulnerability in the SiteManager-Embedded (SM-E) Web server. An attacker can craft a malicious URL containing JavaScript code that, when visited by an authenticated user, executes in the user's browser within the context of their session, allowing session hijacking or other client-side attacks.

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 if Secomea SiteManager-Embedded is runningCheck your systems for the Secomea SiteManager-Embedded web service. This is typically deployed as an appliance or embedded device. Look for the SM-E web interface on common ports like 80, 443, or 8080.Affected if The SiteManager-Embedded web server is accessible on your network and responds to HTTP/HTTPS requests.
-
Determine the installed versionLog into the SiteManager-Embedded administrative interface and navigate to the system information or about page. Alternatively, check the firmware or software version reported in the device management console.Affected if The installed version is any version prior to 9.2c (for example, 9.2, 9.1, 9.0, or earlier).
-
Verify the web interface is externally or internally accessibleConfirm that the SiteManager-Embedded web server is reachable via a browser. Try accessing the login page using the device IP or hostname.Affected if The web interface is accessible and accepts user authentication.
-
Confirm authentication is required for exploitationNote that this is a reflected XSS requiring a user to be authenticated. The attack relies on a victim visiting a malicious URL while logged into the session.Affected if Users authenticate to the SiteManager-Embedded web interface, and the application reflects URL parameters back into the response without sanitization.
You are affected if Secomea SiteManager-Embedded is running with a version lower than 9.2c and users authenticate to its web interface, as the reflected XSS can be triggered via malicious URLs in authenticated sessions.

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 data9.2c
Upgrade SiteManager-Embedded to version 9.3 or later. If immediate upgrade is not possible, implement URL parameter validation and output encoding on the web server to sanitize user-supplied input before rendering.
