CVE-2025-31975
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 · uneditedHCL BigFix Service Management (SM) is affected by an Information Disclosure – Server Banner issue was identified. Exposed server banners may reveal software versions and system details, potentially aiding attackers in targeting known vulnerabilities.
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 confidenceHCL BigFix Service Management exposes server banners that reveal software versions and system details. Attackers can use this information during reconnaissance to identify specific vulnerabilities associated with the disclosed versions.

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 HCL BigFix Service Management is installedCheck if the application is running by accessing the web interface or reviewing running services on the host. Look for processes or services related to BigFix or port 443/8080 if the web interface is accessible.Affected if The product is present and running on the system
-
Check HTTP response headers for server bannerSend an HTTP request to the BigFix web interface (e.g., using curl -I https://<hostname>/ or similar) and inspect the Server header and any custom headers in the response.Affected if The Server header or other headers reveal version numbers, build information, or system details such as Apache, IIS, or specific version strings
-
Identify disclosed version informationReview all HTTP headers in the response for any version numbers, product names, or system information including X-Powered-By, Server, X-Generator, or custom headers.Affected if Any HTTP header exposes the BigFix version (23.0), underlying web server type/version, or operating system details
-
Verify banner exposure through error pagesTrigger an error condition (such as a 404 or 500 error) by requesting a non-existent page and inspect the error response for version or system information in the body or headers.Affected if Error pages contain version numbers, stack traces, or system configuration details
The environment is affected if HCL BigFix Service Management 23.0 is running and HTTP responses contain version numbers, product names, or system details in any header or error page content.

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 or application to suppress or obscure server banner information in HTTP responses, limiting exposure of version and system details.
