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 · unedited
Huang Yaoshi Pharmaceutical Management Software through 16.0 allows arbitrary file upload via a .asp filename in the fileName element of the UploadFile element in a SOAP request to /XSDService.asmx.

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 confidence

Huang Yaoshi Pharmaceutical Management Software through version 16.0 contains an arbitrary file upload vulnerability in /XSDService.asmx. Attackers can upload malicious .asp files by manipulating the fileName element within the UploadFile element in a SOAP request, achieving remote code execution.

MitigationImmediately restrict or disable the XSDService.asmx upload functionality until a vendor patch is available. Implement strict server-side file type validation (whitelist approach), validate file extensions and MIME types, store uploads outside web root, and apply proper access controls.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Huang Yaoshi Pharmaceutical Management Software is installed
    Check for the software in standard installation directories (commonly C:\Program Files\Huang Yaoshi or similar), or look for running processes with names like 'HuangYaoshi' or 'HYSMG'. Check Windows Services or Linux service listings for the application.
    Affected if The software is installed and running on the system
  2. Determine the installed version
    Locate the main executable (often named similar to the product) and check its version properties. Common paths: C:\Program Files\Huang Yaoshi\Pharmaceutical Management\ or check the About/Help section within the application UI for the version number.
    Affected if The installed version is 16.0 or any earlier version (up to and including 16.0)
  3. Verify the /XSDService.asmx endpoint is accessible
    From a system that can reach the application server, attempt an HTTP/HTTPS request to the endpoint: http(s)://<server>/XSDService.asmx . A successful connection returning a SOAP service page indicates the endpoint is exposed.
    Affected if The endpoint returns a valid SOAP service response, meaning it is accessible over the network
  4. Confirm the UploadFile SOAP operation is available
    Access the XSDService.asmx page and look for the UploadFile method in the listed operations. Alternatively, examine the WSDL if exposed, or attempt a test request with the UploadFile SOAP action.
    Affected if The UploadFile method is listed or responds to SOAP requests, indicating the vulnerable function is enabled
  5. Check if the application accepts file uploads without proper validation
    Send a test SOAP request to the UploadFile operation with a benign file extension in the fileName parameter. Observe whether the application accepts and stores the file without rejecting it based on extension whitelist validation.
    Affected if The application accepts arbitrary file extensions (such as .asp, .aspx, .php) in the fileName element without validation

A system is affected if Huang Yaoshi Pharmaceutical Management Software version 16.0 or earlier is installed and the /XSDService.asmx endpoint with the UploadFile method is accessible and accepts files without extension validation.

Mitigation

Immediately restrict or disable the XSDService.asmx upload functionality until a vendor patch is available. Implement strict server-side file type validation (whitelist approach), validate file extensions and MIME types, store uploads outside web root, and apply proper access controls.
