Name of the Vulnerable Software and Affected Versions Open-Xchange OX App Suite versions prior to 7.8.2-rev5

Description An issue allows JavaScript code to be executed within a user's context when it is included in ical attachments within scheduling emails. This code can be presented to the user in the E-Mail App, depending on the invitation workflow, and can lead to malicious script execution.
