CVE-2016-4027: n/a vulnerability

CVE-2016-4027: An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev10.

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev10. App Suite frontend offers to control whether a user wants to store cookies that exceed the session duration. This functionality is useful when logging in from clients with reduced privileges or shared environments. However the setting was incorrectly recognized and cookies were stored regardless of this setting when the login was performed using a non-interactive login method. In case the setting was enforced by middleware configuration or the user went through the interactive login page, the workflow was correct. Cookies with authentication information may become available to other users on shared environments. In case the user did not properly log out from the session, third parties with access to the same client can access a user's account.

Security readout for executives and security teams

This flaw could leave Open-Xchange OX App Suite login cookies on a shared computer even when users expected them not to persist. If a user does not log out, another person using the same client may be able to access that account. Exposure is most likely in deployments running OX App Suite before 7.8.1-rev10 that allow non-interactive login from shared, kiosk, lab, or otherwise multi-user clients. Treat as a moderate-priority privacy and account-access risk, highest for shared-device environments. Patch during the next planned maintenance window, sooner for kiosks or multi-user workstations. Mitigation focus: Upgrade OX App Suite to 7.8.1-rev10 or a later vendor-supported build.; Enforce the cookie persistence setting through middleware configuration where available.; Reduce or disable non-interactive login paths on shared clients until fixed..
