A vulnerability in the legacy chat component of Mitel MiContact Center Business through 10.2.0.3 could allow an unauthenticated attacker to conduct an information disclosure attack due to improper handling of session data. A successful exploit requires user interaction and could allow an attacker to access sensitive information, leading to unauthorized access to active chat rooms, reading chat data, and sending messages during an active chat session.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
