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
A security vulnerability has been detected in Kingdee Cloud-Starry-Sky Enterprise Edition up to 8.2. This issue affects the function BaseServiceFactory.getFileUploadService.deleteFileAction of the file K3Cloud\BBCMallSite\WEB-INF\lib\Kingdee.K3.O2O.Base.WebApp.jar!\kingdee\k3\o2o\base\webapp\action\FileUploadAction.class of the component IIS-K3CloudMiniApp. The manipulation of the argument filePath leads to path traversal. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. It is suggested to install a patch to address this issue. The vendor recommends as a short-term measure to "[t]emporarily disable external network access to the Kingdee Cloud Galaxy Retail System or set up an IP whitelist for access control." The long-term remediation will be: "Install the security patch provided by the Starry Sky system, with the specific solutions being: i) Adding authentication to the vulnerable CMKAppWebHandler.ashx interface; ii) Removing the file reading function."

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

Path traversal vulnerability in Kingdee Cloud-Starry-Sky Enterprise Edition (up to 8.2) allows remote attackers to manipulate the filePath argument in the deleteFileAction function of the FileUploadAction.class component (IIS-K3CloudMiniApp), potentially enabling unauthorized file deletion or access to arbitrary system files.

MitigationImmediately restrict external network access or implement IP whitelisting; apply vendor security patch by adding authentication to the CMKAppWebHandler.ashx interface or remove the vulnerable file reading function entirely.

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 Kingdee Cloud-Starter-Sky installation
    Locate the Kingdee installation directory or check Windows Programs and Features for 'Kingdee Cloud-Starry-Sky Enterprise Edition'
    Affected if The software is installed on the system
  2. Check installed version number
    In the installation directory, look for version information in about dialog, config files, or registry keys under HKLM\Software\Kingdee or HKLM\Software\Wow6432Node\Kingdee
    Affected if The version is 8.2 or lower (including unversioned installs)
  3. Verify IIS-K3CloudMiniApp component exists
    Check for the K3CloudMiniApp folder in the IIS web root (typically C:\inetpub\wwwroot\ or the Kingdee web application directory)
    Affected if The K3CloudMiniApp web folder is present
  4. Locate vulnerable FileUploadAction.class
    Search for FileUploadAction.class within the K3CloudMiniApp directory structure, typically in a bin or WEB-INF/classes folder
    Affected if FileUploadAction.class exists in the deployed application
  5. Confirm deleteFileAction function is accessible
    Check if the web application endpoint for deleteFileAction is accessible (typically exposed via .ashx handler). Test network access to the CMKAppWebHandler.ashx interface
    Affected if The deleteFileAction endpoint is exposed without authentication requirements

The environment is affected if Kingdee Cloud-Starry-Sky Enterprise Edition version 8.2 or lower is installed with the K3CloudMiniApp component deployed and the FileUploadAction.class with deleteFileAction function accessible without authentication.
