Product: Open-Xchange Server 6 / OX AppSuite Vendor: Open-Xchange GmbH Internal reference: 35889 (Bug ID) Vulnerability type: Information Exposure (CWE-200) Vulnerable version: 7.6.1 and earlier Vulnerable component: backend Report confidence: Confirmed Solution status: Fixed by Vendor Fixed version: 7.4.2-rev42, 7.6.0-rev36, 7.6.1-rev14 Vendor notification: 2014-12-17 Solution date: 2015-01-13 CVE reference: CVE-2014-9466 CVSSv2: 6.0 (AV:N/AC:M/Au:S/C:P/I:N/A:N/E:F/RL:U/RC:C/CDP:MH/TD:H/CR:M/IR:ND/AR:ND) Vulnerability Details: Publications allow sharing files with external data consumers. Access to those is secured with a random hash and publications allow access to the shared directory or file only. However, since the folder identifier has not been properly taken into consideration when calculating permissions, a user that obtained access to the publication is able to access other files which are not intentionally published by the owner. Risk: External users that have valid access to a publication may access files that are not intended to be shared with them. Solution: Users should update to the latest patch releases 7.4.2-rev42, 7.6.0-rev36 and 7.6.1-rev14 (or later).
