CVE-2025-55272
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 Aftermarket DPC is affected by Banner Disclosure vulnerability where attackers gain insights into the system’s software and version details which would allow them to craft software specific attacks.
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 Aftermarket DPC exposes software version and system information through its banners, allowing remote attackers to perform reconnaissance and identify specific software versions for targeted attacks. This banner disclosure vulnerability leaks critical system metadata that should be suppressed in production environments.

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 Aftermarket Cloud installationLocate and inspect the application installation directory or check running processes for 'aftermarket' or 'HCL' components. Query the package manager or application inventory for Hcltech Aftermarket Cloud version 1.0.0.Affected if Hcltech Aftermarket Cloud version 1.0.0 is installed and running.
-
Inspect HTTP response headers for version disclosureSend a baseline HTTP request to the application's web endpoints using curl -I or browser developer tools. Examine all response headers, particularly Server, X-Powered-By, and custom headers for version numbers, build identifiers, or HCL product strings.Affected if Response headers contain version numbers, build information, or HCL product identifiers that reveal the software version.
-
Check default error pages for information leakageTrigger error conditions by requesting non-existent pages or sending malformed requests. Examine the returned error pages for stack traces, framework versions, or system information.Affected if Error pages display version numbers, framework details, or system metadata.
-
Review web server or proxy configuration for banner suppressionExamine configuration files for the underlying web server (e.g., httpd.conf, nginx.conf) or reverse proxy for ServerTokens, ServerSignature, or similar directives that control banner disclosure. Check if masking is enabled.Affected if Server configuration allows version banners to be displayed, or banner masking is not explicitly enabled.
A system is affected if HCL Aftermarket Cloud version 1.0.0 is running and HTTP responses, error pages, or server configuration expose version or system information that should be suppressed.

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 application and underlying web server to suppress version banners and disable verbose error messages that reveal software stack details. Implement proper banner masking through server configuration or reverse proxy settings.
