FusionPBX XSS 16

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\recordings\recording_play.php uses an unsanitized “filename” variable coming from the URL which is base64 decoded and reflected in HTML leading to XSS.
