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 RemoteFunctions endpoint with missing access control in konzept-ix publiXone before 2020.015 allows attackers to disclose sensitive user information, send arbitrary e-mails, escalate the privileges of arbitrary user accounts, and have unspecified other impact.

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

The RemoteFunctions API endpoint in konzept-ix publiXone lacks authentication and authorization controls, allowing unauthenticated attackers to invoke sensitive functions. This enables disclosure of user PII, sending of arbitrary emails via the system, and privilege escalation to administrator accounts.

MitigationApply vendor patch version 2020.015 or later to implement proper access control on the RemoteFunctions endpoint. If patching is delayed, restrict network access to the endpoint at the firewall level.

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 Konzept Ix Publixone is installed
    Check for konzept-ix publiXone web application files in the web server document root, typically found in directories like /var/www/, /www/, or C:\inetpub\. Look for application files with naming patterns containing 'publixone' or 'ix'.
    Affected if The application is present on the system and is a version prior to 2020.015
  2. Determine the installed version
    Locate the version information file or check the application header/footer for the build or version number. Common locations include a version.txt file, config/application.conf, or the About page in the web interface.
    Affected if The installed version is lower than 2020.015
  3. Verify the RemoteFunctions endpoint is accessible
    Attempt to access the RemoteFunctions API endpoint via HTTP/HTTPS. Common endpoint paths include /RemoteFunctions, /api/RemoteFunctions, or /services/RemoteFunctions. Use curl or a browser to send a request to this endpoint.
    Affected if The endpoint responds without requiring authentication (returns 200 OK or application data rather than redirecting to a login page or returning 401/403)
  4. Check network exposure of the endpoint
    Review firewall rules and web server configuration to determine if the RemoteFunctions endpoint is exposed to untrusted networks. Check if the web application is accessible from the internet or only from trusted internal networks.
    Affected if The endpoint is reachable from untrusted network segments or the internet

A defender is affected if Konzept Ix Publixone version is below 2020.015 AND the RemoteFunctions API endpoint is accessible without authentication.

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.

dbcve · scoped
Upgrade available Upgrade to 2020.015 or later
Fixed in 2020.015
Interim mitigation

Apply vendor patch version 2020.015 or later to implement proper access control on the RemoteFunctions endpoint. If patching is delayed, restrict network access to the endpoint at the firewall level.

Recommended fix Moderate confidence

2020.015

  1. Contact konzept-ix support to obtain the upgrade to version 2020.015 or later
  2. Request the official upgrade package/documentation from the vendor
  3. Follow the vendor-provided upgrade instructions to apply the update
  4. After upgrading, verify that the RemoteFunctions endpoint now has proper access controls
  5. Test to confirm sensitive user information is no longer accessible without authentication
