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 · uneditedImproper Input Validation, Cross-site Scripting (XSS) vulnerability in Web GUI of Secomea GateManager allows an attacker to execute arbitrary javascript code. This issue affects: Secomea GateManager all versions prior to 9.4.
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 confidenceA cross-site scripting (XSS) vulnerability exists in the Web GUI of Secomea GateManager due to improper input validation. An attacker can inject and execute arbitrary JavaScript code in the context of a victim's browser by submitting malicious input through 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.
-
Confirm Secomea GateManager is deployedIdentify the device or system in your environment running Secomea GateManager. This is typically a GateManager appliance or virtual instance. Check your asset inventory or network documentation for Secomea devices.Affected if The target system is a Secomea GateManager device or virtual appliance
-
Locate the firmware versionAccess the GateManager administrative interface or check the system documentation for the installed firmware version. The version is typically displayed in the main dashboard or system information page of the web GUI.Affected if Unable to determine the firmware version for comparison
-
Compare installed version to affected rangeCompare your installed firmware version against the affected range: versions prior to 9.4.62105402. If your version number is lower than 9.4.62105402, you are in the affected range.Affected if Installed firmware version is lower than 9.4.62105402
-
Verify Web GUI is accessibleConfirm the GateManager web interface is enabled and accessible. Since this is a web GUI XSS vulnerability, the attack vector requires the web interface to be reachable. Check if port 443 or 80 is open and the web service is running.Affected if Web GUI is exposed and version is in the affected range
You are affected if your Secomea GateManager firmware version is below 9.4.62105402 and the web GUI interface is accessible
