The Sangoma and FreePBX team has deemed this a major security issue. We strongly encourage all users of FreePBX 13, 14 and 15 to upgrade to the latest version of the userman 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 request that any future FreePBX security issue be reported at security@freepbx.org.
