Blind SQL injection in ManageEngine Desktop Central, Password Manager
Pro and IT360 (including MSP versions)
Scroll to the bottom for the Metasploit module link; the module will
be submitted to Metasploit proper in a pull request in the next few
days.

>> Blind SQL injection in ManageEngine Desktop Central, Password Manager Pro and IT360 (including MSP versions)
>> Discovered by Pedro Ribeiro (pedrib@gmail.com), 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.
  
#1
Vulnerability:
Blind SQL injection in LinkViewFetchServlet (unauthenticated on DC/PMP
/ authenticated on IT360)
CVE-2014-3996
  
Affected products / versions:
- ManageEngine Desktop Central (DC) [MSP]: all versions from v4 up to
v9 build 90033
- ManageEngine Password Manager Pro (PMP) [MSP]: all versions from v5
to version 7 build 7002
- ManageEngine IT360 [MSP]: all versions from v8 to v10.1.1 build 10110
This affects all versions of the products released since 19-Apr-2006.
Other ManageEngine products might be affected.
  
Constraints:
- DC: no authentication or any other information needed
- PMP: no authentication or any other information needed
- IT360: valid user account needed
  
Proof of concept:
  
DC / PMP:
GET /LinkViewFetchServlet.dat?sv=[SQLi]
  
IT360:
GET /console/LinkViewFetchServlet.dat?sv=[SQLi]
  
  
#2
Vulnerability:
Blind SQL injection in MetadataServlet (unauthenticated on PMP /
authenticated on IT360)
CVE-2014-3997
  
Affected products / versions:
- ManageEngine Password Manager Pro (PMP) [MSP]: all versions from v5
to version 7 build 7003
- ManageEngine IT360 [MSP]: all versions from v8 to v10.1.1 build 10110
This affects all versions of the products released since 03-Apr-2008.
Other ManageEngine products might be affected.
  
Constraints:
- PMP: no authentication or any other information needed
- IT360: valid user account needed
  
Proof of concept:
  
PMP:
GET /MetadataServlet.dat?sv=[SQLi]
  
IT360:
GET /console/MetadataServlet.dat?sv=[SQLi]

      '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.
