CVE-2019-16987

Name of the Vulnerable Software and Affected Versions FusionPBX versions prior to 4.5.8

Description The issue concerns the use of an unsanitized query string variable in the contact import.php file, which is reflected in HTML. This leads to a cross-site scripting (XSS) issue, allowing potential attackers to inject malicious scripts into the application.

Recommendations For FusionPBX versions prior to 4.5.8, update to version 4.5.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the contact import.php file to minimize the risk of exploitation. Avoid using the query string variable in the affected URL until the issue is resolved.
