CVE-2020-11595Network attack vector

Unauthenticated upload-path disclosure via API response

Published Apr 6, 2020 · Updated Aug 4, 2024

Information disclosure in CIPPlanner CIPAce 9.1 Build 2019092801 allows remote attackers to obtain the upload folder path via an API request. The affected API response returns the server's upload directory as a UNC path containing its hostname; the public record does not identify the endpoint or handler. No authentication or user interaction is required, and the demonstrated consequence is disclosure of server naming and filesystem-layout details rather than file contents or modification.
