FusionPBX XSS 7

An attacker targeting an authenticated user can push him to click on a URL of FusionPBX 4.5.7 specially crafted to get javascript code executed in his browser.

In FusionPBX up to v4.5.7, file app\contacts\contact_times.php uses an unsanitized “id” variable coming from the URL which is reflected in HTML leading to XSS.
