CVE-2019-19002
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 · uneditedFor ABB eSOMS versions 4.0 to 6.0.2, the X-XSS-Protection HTTP response header is not set in responses from the web server. For older web browser not supporting Content Security Policy, this might increase the risk of Cross Site Scripting.
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 confidenceThe ABB eSOMS web server (versions 4.0 to 6.0.2) does not include the X-XSS-Protection HTTP response header in its responses. This header instructs browsers to enable built-in XSS filtering. While modern browsers support Content Security Policy (CSP), older browsers rely on this header for XSS protection, making reflected XSS attacks more feasible against users of legacy browsers.

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 ABB eSOMS web server is runningIdentify the eSOMS web server process or service on the system. Check running processes or services for 'eSOMS' or verify the web application is accessible on its expected port (typically 80/443 or configured port).Affected if The ABB eSOMS web server (versions 4.0 to 6.0.2) is running and serving HTTP responses.
-
Capture an HTTP response from the web serverSend an HTTP request (e.g., using curl -I http://<server>:<port>/ or similar) to the eSOMS web server and capture the response headers. This can be done from the server locally or a remote client able to reach the web interface.Affected if You are able to retrieve HTTP response headers from the eSOMS web server.
-
Inspect for X-XSS-Protection headerExamine the captured HTTP response headers specifically for the 'X-XSS-Protection' header. Look for entries such as 'X-XSS-Protection: 1; mode=block' or similar values.Affected if The header is completely absent from the HTTP response headers.
If the X-XSS-Protection header is not present in HTTP responses from the ABB eSOMS web server (versions 4.0 to 6.0.2), the environment is affected by this CVE.

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 dataConfigure the web server to include the X-XSS-Protection: 1; mode=block header in all HTTP responses, or implement Content Security Policy (CSP) as a more comprehensive modern alternative.
