Recommendation: Plan a near-term fix — a public PoC already exists.

The conferencing component on Mitel ShoreTel 19.46.1802.0 devices could allow an unauthenticated attacker to conduct a reflected cross-site scripting (XSS) attack (via the PATH_INFO to index.php) due to insufficient validation for the time_zone object in the HOME_MEETING& page.
