CVE-2019-16973

Name of the Vulnerable Software and Affected Versions FusionPBX versions up to 4.5.7

Description The issue concerns the use of an unsanitized query string variable in the file appcontactscontact edit.php, which is reflected in HTML and leads to a cross-site scripting (XSS) issue. This occurs when the variable comes from the URL.

Recommendations For FusionPBX versions up to 4.5.7, as a temporary workaround, consider sanitizing the query string variable in the contact edit.php file to prevent XSS attacks. Restrict access to the contact edit.php file until a proper fix is applied.
