CVE-2020-27180
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 · uneditedkonzept-ix publiXone before 2020.015 allows attackers to download files by iterating over the IXCopy fileID parameter.
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 confidenceThis is an Insecure Direct Object Reference (IDOR) vulnerability in konzept-ix publiXone before version 2020.015. The application uses a predictable IXCopy fileID parameter to reference files for download without proper authorization checks, allowing unauthenticated attackers to enumerate and download arbitrary files on the system by iterating through fileID values.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify if publixone is installedCheck installed programs or application directories for konzept-ix publixone or publiXone. Check web server configs for any publixone-related virtual directories or applications.Affected if publixone is found and running in the environment
-
Determine the installed versionInspect application metadata, version files, or the application itself for a version number. Compare against 2020.015.Affected if The installed version is less than 2020.015 (e.g., 2020.014, earlier releases)
-
Verify the IXCopy endpoint existsCheck web server access logs for IXCopy requests, or inspect the application URL structure for any endpoint containing IXCopy or file download functionality.Affected if The IXCopy endpoint is accessible and responds to requests
-
Test for unauthenticated file accessSend a request to the IXCopy endpoint with a fileID parameter (e.g., ?fileID=1 or similar pattern) without providing authentication credentials. Observe if files can be downloaded.Affected if Files are returned without requiring authentication or authorization validation
The environment is affected if publixone version is below 2020.015 and the IXCopy endpoint allows unauthenticated file downloads via predictable fileID values.

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.
From vendor data2020.015
Upgrade to pubiXone version 2020.015 or later which includes proper authorization validation on the IXCopy file download endpoint. Until patched, monitor access logs for unusual patterns of IXCopy requests.
