Open-Xchange AppSuite any version

Connections to external data sources, like e-mail autoconfiguration, were not terminated in case they hit a timeout, instead those connections were logged. Some connections use user-controlled endpoints, which could be malicious and attempt to keep the connection open for an extended period of time. As a result users were able to trigger large amount of egress network connections, possibly exhausting network pool resources and lock up legitimate requests. A new mechanism has been introduced to cancel external connections that might access user-controlled endpoints. No publicly available exploits are known.

XML External Entity (XXE) vulnerability in the CalDAV interface in Open-Xchange (OX) AppSuite 7.4.1 and earlier allows remote authenticated users to read portions of arbitrary files via vectors related to the SAX builder and the WebDAV interface. NOTE: this issue has been labeled as both absolute path traversal and XXE, but the root cause may be XXE, since XXE can be exploited to conduct absolute path traversal and other attacks.

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.

Multiple cross-site scripting (XSS) vulnerabilities in Open-Xchange AppSuite before 7.2.2 allow remote authenticated users to inject arbitrary web script or HTML via (1) content with the text/xml MIME type or (2) the Status comment field of an appointment.

OX App Suite 7.10.1 and earlier has Insecure Permissions.
