A vulnerability in the Multimedia Email component of Mitel MiContact Center Business through 10.2.0.10 and Mitel CX through 1.1.0.1 could allow an unauthenticated attacker to conduct a Cross-Site Scripting (XSS) attack due to insufficient input validation. A successful exploit requires user interaction where the email channel is enabled. This could allow an attacker to execute arbitrary scripts in the victim's browser or desktop client application.
