CVE-2020-11594Network attack vector

Server path disclosure via verbose API errors

Published Apr 6, 2020 · Updated Aug 4, 2024

Information disclosure in CIPPlanner CIPAce 9.1 Build 2019092801 allows remote attackers to obtain a server file path via an API request. An unspecified API handler returns a stack error containing the application's full filesystem path instead of suppressing internal exception details. No authentication or user interaction is required; disclosure is limited to path information that can aid follow-on targeting.
