CVE-2019-19371

Estado: ModificadaMedia (6.1)—

A cross-site scripting (XSS) vulnerability in the web conferencing component of Mitel MiCollab AWV before 8.1.2.2 could allow an unauthenticated attacker to conduct a reflected cross-site scripting (XSS) attack due to insufficient validation in the join meeting interface. A successful exploit could allow an attacker to execute arbitrary scripts.
