Server path disclosure via readEASFile responses

Published Oct 20, 2021 · Updated Sep 25, 2024

Information disclosure in Oracle Essbase Administration Services before 11.1.2.4.046 and before 21.3 lets remote attackers read server paths. The EAS Console's EssbaseFileObjectCommands.readEASFile operation returns scripts or reports with absolute filesystem paths embedded in the HTTP response. No authentication or user interaction is required; disclosure is limited to path data and does not alter data or interrupt service.
