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
Unrestricted Upload of File with Dangerous Type vulnerability in TalentSys Consulting Information Technology Industry Inc. Inka.Net allows Command Injection. This issue affects Inka.Net: before 6.7.1.

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

Inka.Net before version 6.7.1 contains an unrestricted file upload vulnerability that allows attackers to upload files with dangerous types (e.g., executable scripts) without proper validation. The lack of file type/content validation enables attackers to upload malicious files that can be leveraged for command injection, achieving remote code execution on the affected server.

MitigationUpgrade Inka.Net to version 6.7.1 or later. Additionally, implement strict allowlist-based file validation (extension, MIME type, magic bytes), store uploads outside webroot, disable script execution in upload directories, and sanitize file names.

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. Locate Inka.Net installation and version
    Identify where Inka.Net is installed on the system. Check the application's version information (e.g., version file, about page, or binary metadata) and compare it to the affected range (versions before 6.7.1).
    Affected if The installed version of Inka.Net is below 6.7.1.
  2. Identify file upload functionality
    Locate the file upload feature or endpoint within the Inka.Net application. This may be a web form, API endpoint, or administrative interface that accepts file uploads.
    Affected if The file upload feature exists and is accessible in the deployment.
  3. Verify file type validation is implemented
    Inspect the file upload handling code or configuration to determine if file type validation is performed. Look for allowlists of permitted extensions, MIME type checks, magic byte verification, or content-based validation.
    Affected if No file type or content validation is enforced on uploaded files, or only weak validation (e.g., client-side only or extension-based only) is present.
  4. Check upload directory configuration
    Examine where uploaded files are stored and whether the upload directory is accessible via the web server (inside webroot). Determine if script execution is disabled in that directory.
    Affected if Uploaded files are stored within the webroot and script execution is not disabled, allowing uploaded scripts to be executed.

The environment is affected if Inka.Net version is below 6.7.1 AND the file upload feature is accessible AND proper file validation is not implemented, allowing malicious file uploads that could lead to remote code execution.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Inka.Net to version 6.7.1 or later. Additionally, implement strict allowlist-based file validation (extension, MIME type, magic bytes), store uploads outside webroot, disable script execution in upload directories, and sanitize file names.

Recommended fix Moderate confidence

Inka.Net 6.7.1 or later

  1. Contact TalentSys Consulting Information Technology Industry Inc. to obtain Inka.Net version 6.7.1 or later
  2. Download the upgrade package from official vendor channels only
  3. Backup current Inka.Net configuration and data before upgrading
  4. Test the upgrade in a non-production/staging environment first
  5. Schedule a maintenance window for production upgrade
  6. Apply the upgrade following vendor-provided installation instructions
  7. Verify the upgrade was successful and the file upload vulnerability is resolved
  8. Monitor for any unusual behavior after deployment
Caveat Review vendor release notes for any configuration or functionality changes between your current version and 6.7.1
