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
An issue was discovered in Biztalk360 before 11.5. Because of mishandling of user-provided input in an upload mechanism, an authenticated attacker is able to write files outside of the destination directory and/or coerce an authentication from the service, aka Directory Traversal.

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

BizTalk360 before version 11.5 contains a directory traversal vulnerability in its file upload mechanism. Due to improper handling of user-supplied input, an authenticated attacker can write files to arbitrary locations on the server outside the intended upload directory, potentially leading to remote code execution or service compromise.

MitigationUpgrade BizTalk360 to version 11.5 or later. Additionally, implement strict input validation and canonicalization on all file upload paths to prevent path traversal attacks.

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. Confirm Biztalk360 installation
    Look for Biztalk360 service in Windows Services, check for Biztalk360 application in IIS Manager, or locate the installation directory (commonly under C:\Program Files\Kovai\BizTalk360 or similar)
    Affected if Biztalk360 is installed and running
  2. Identify installed version
    Check the version information in the Biztalk360 UI (typically in the About or Settings section), or look for a version file in the installation directory
    Affected if The version number cannot be determined or is below 11.6.3963.2611
  3. Compare version to affected range
    Compare your installed version against the affected range: versions below 11.6.3963.2611 are vulnerable
    Affected if Installed version is less than 11.6.3963.2611
  4. Verify file upload feature accessibility
    Check if the file upload functionality is available in the Biztalk360 interface (typically under Settings, Administration, or specific operational sections where file imports are permitted)
    Affected if The file upload feature is accessible to authenticated users
  5. Confirm authentication is required
    Verify that the Biztalk360 application requires authentication (local Windows authentication or application-level login)
    Affected if An attacker can authenticate to access the file upload mechanism

Your environment is affected if Biztalk360 is installed with a version below 11.6.3963.2611 and the file upload feature is accessible to authenticated users.
