CVE-2025-55267
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 Unrestricted File Upload vulnerability, allows attacker to upload and execute malicious scripts, gaining full control over the server.
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 contains an unrestricted file upload vulnerability that fails to properly validate uploaded files, allowing attackers to upload malicious scripts (such as web shells) and execute them to achieve full server compromise.

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 the installed version of HCL Aftermarket CloudLocate the product version information in the system configuration, about page, or installation manifest. Common locations include the admin panel, version file, or system information endpoint.Affected if The installed version is exactly 1.0.0 (the only affected version listed)
-
Confirm the product is HCL Aftermarket Cloud (not another HCL product)Verify that the application is specifically the Aftermarket Cloud component, not another HCL product line. Check product name in license, header, or system identification.Affected if The product is HCL Aftermarket Cloud version 1.0.0
-
Identify if file upload functionality exists and is enabledLocate the file upload module or endpoint in the application. This may be found in the web interface, API documentation, or by scanning for upload-related routes/paths.Affected if The file upload feature is present and accessible
-
Inspect web-accessible directories for unexpected filesSearch web server directories (such as /uploads, /images, /attachments, /media, or web root) for files with extensions like .php, .jsp, .asp, .exe, .sh, or other executable/script types that were not intentionally uploaded by administrators.Affected if Unexpected script or executable files exist in web-accessible directories
-
Review upload directory configuration for script execution permissionsCheck web server or application configuration to determine if script execution is allowed in directories where uploaded files are stored.Affected if Script execution is permitted in upload directories (this would indicate the vulnerability is exploitable)
A user is affected if they are running HCL Aftermarket Cloud version 1.0.0 with the file upload feature enabled and accessible.

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 dataImplement strict file type validation using magic byte verification, store uploads outside the webroot, rename files to prevent script execution, and disable script execution permissions in upload directories.
