CVE-2019-11408
XSS in app/operator_panel/index_inc.php in the Operator Panel module in FusionPBX 4.4.3 allows remote unauthenticated attackers to inject arbitrary JavaScript characters by placing a phone call using a specially crafted caller ID number.
Does this matter?
Lower severity and a low EPSS score (6.87%). Track it; it rarely justifies an emergency change on its own.
Description
XSS in app/operator_panel/index_inc.php in the Operator Panel module in FusionPBX 4.4.3 allows remote unauthenticated attackers to inject arbitrary JavaScript characters by placing a phone call using a specially crafted caller ID number. This can further lead to remote code execution by chaining this vulnerability with a command injection vulnerability also present in FusionPBX.
