Further Details:

A XSS vulnerability exists on the Call Event Logging report screen in the ‘cel’ module. Eg. /admin/config.php?display=cel. An attacker can inject javascript code through the date fields.

The Sangoma and FreePBX team has deemed this a major security issue. We strongly encourage all users of FreePBX versions 13, 14, and 15 to upgrade to the latest version of the cel module. This can be done from the Module Admin GUI or fwconsole. For more information on using Module Admin, please see http://wiki.freepbx.org/display/FPG/Module+Admin+User+Guide.

Sangoma takes security seriously and requests that any future FreePBX security issue be reported at security@freepbx.org.
